Day. Welcome to Five9's second quarter 2019 earnings conference call. Today's conference is being recorded. At this time, I would like to turn the conference over to Ms. Lisa Liguori. Please go ahead, ma'am.
Thank you, operator. Good afternoon, everyone, and thank you for joining us on today's conference call to discuss Five9's second quarter 2019 results. Today's call is being hosted by Rowan Trollope, CEO, Dan Burkland, President, and Barry Zwarenstein, CFO. During the course of this conference call, Five9's management team will make projections and other forward-looking statements regarding the future financial performance of the company, industry trends, company initiatives, and other future events. You are cautioned that such statements are simply predictions, should not be unduly relied upon by investors, and actual events or results may differ materially, and the company undertakes no obligation to update the information in such statements. These statements are subject to substantial risks and uncertainties that could adversely affect Five9's future results and cause these forward-looking statements to be inaccurate.
A more detailed discussion of certain risk factors that could cause these forward-looking statements to be inaccurate that you should consider in evaluating Five9 in its prospects is included under the caption Risk Factors and elsewhere in Five9's filings with the Securities and Exchange Commission. In addition, management will make reference to non-GAAP financial measures during the call. Management believes that this non-GAAP information is useful because it can enhance an understanding of the company's ongoing performance, and Five9 therefore uses non-GAAP financial information internally to evaluate and manage the company's operations. This non-GAAP financial information should be considered along with, and not as a replacement for, financial information reported under GAAP and could be different from the non-GAAP financial information provided by other companies in our industry.
The full reconciliation of GAAP to non-GAAP financial data can be found in the company's press release issued earlier this afternoon and is also available on the investor relations section of Five9's website. Now I'd like to turn the call over to Five9 CEO, Rowan Trollope.
Thank you, Lisa. Thanks to all of you for joining our call this afternoon. We delivered strong second quarter results with $77.4 million in revenue, up 27% year-over-year. Our adjusted EBITDA margin was 18.6%, an increase of 2.7 percentage points year-over-year. Terrific results for the company, demonstrating the strength of our business model. Now our enterprise business is driving the top line, with subscriptions growing at 36% LTM. This enterprise growth is most pronounced with our largest customers, paying more than $1 million in annually recurring revenue that now make up over a quarter of our LTM revenue and are the fastest-growing part of our business, with a CAGR in the 50s over the last three years. I'll now turn the call over to our President, Dan Burkland, to talk about the great bookings quarter we just completed. Dan?
Thank you, Rowan. Our Q2 enterprise bookings grew strongly year-over-year and reached an all-time record by far for any quarter. Our pipeline also reached another all-time high. This quarter, we continue to see larger and larger deals coming in, and more than 60% of deals were influenced by our ecosystem of partners. Now I'd like to share some key enterprise wins for the quarter. The first example is a pharmaceutical company that serves patients during clinical trials for life-saving treatments. They were unable to deliver an optimal customer experience due to several limiting factors and reliability concerns of their then cloud-based solution. They were having service interruptions, had limited integration with their custom CRM, and had a very basic workforce management solution with no intraday reporting, which made staff forecasting very difficult. They also couldn't support the call peaks, which were over 1,500 concurrent calls.
Five9 delivered the best solution to each of these pain points with the end-to-end solution offering, including Five9 WFO powered by Verint for workforce management, quality management, and performance management. This initial order is anticipated to result in nearly $1.5 million in annual recurring revenue to Five9. The second example I'd like to share with you is a financial services company in the automotive sector, which takes calls and inquiries from dealerships and consumers. They were using a premises-based Aspect system, which had become unreliable and had limited integration to Salesforce. They were experiencing excessive downtime, which was directly impacting their revenue. Aspect attempted to migrate the customer to their own cloud solution but discovered that it could not scale beyond 1,000 agents. With Five9's uptime, reliability, scalability, and simplicity of administering the system, we are implementing a complete end-to-end solution to deliver exceptional customer experiences.
This initial order is anticipated to result in over $2.5 million in annual recurring revenue to Five9. The third example is a dentistry company providing orthodontic solutions direct to consumers globally. Their existing solution did not have an elegant way of doing true blending for inbound and outbound calling, nor an easy way to accomplish omni-channel routing with Salesforce. They also experienced difficulties with international dialing, identifying country of origin for digital channels, and a manual process for resetting skills. Solving these challenges, along with finding a partner who would provide them with the consultation and ongoing high-touch optimization, led them directly to Five9. This initial order is anticipated to result in over $2.7 million in annual recurring revenue to Five9. Now, as we usually do, I'll share a significant expansion of an installed base enterprise customer.
This is one of the fastest-growing insurance brokers offering quotes for medical, auto, home, and life insurance, who had been a sizable customer of Five9 since 2016. Since their initial Five9 deployment, the customer has added three additional business units, with the most recent department bringing their contact center seat total to nearly 2,000. With this add-on order of over $1.2 million, it now brings their anticipated annual recurring revenue to $3.4 million to Five9 across multiple U.S. locations. As you can see, we continue to execute upmarket with larger customers while also helping expand our footprint and offerings within our growing customer base. With that, I'll turn it back to you, Rowan.
Thanks, Dan. Terrific examples. Now I'd like to turn to some comments on our business and share with you why I believe that Five9 is set to enjoy many years of '30s level enterprise growth. I'd like to share with you the three key pillars that I see driving that growth. The first pillar is the market, which with a TAM of over $24 billion, is massive. Start with the fact that the transition to the cloud of this big market is in its early innings, at under 15% penetration. Next, we're through the evangelical phase of the cloud, notably demonstrated by Gartner's decision recently to discontinue the Magic Quadrant for on-premises contact center vendors. Finally, the priority of the contact center is on the rise, as company leaders all over the world recognize that transforming their customer service experience is a necessity.
This transformation fundamentally repositions the contact center from a cost center into a business differentiator that is worthy of investment. That's the market. The second pillar is our product. First, Five9 and our product has consistently been included by Gartner in their Magic Quadrant as an industry leader. That's a result of over a decade of experience and investment, working with increasingly larger customers, building out a hardened and versatile platform with a very large surface area of capabilities. This iterative scaling of the product is not something that can be easily replicated by aspiring new market entrants. Next, to further strengthen our product, we have meaningfully expanded our engineering leadership and are increasing our investment in R&D. Our new leaders are Jonathan Rosenberg, our CTO and head of AI, and Dave Pickering, our head of engineering.
On July 15th, we announced Anand Chandrasekaran, formerly from Facebook, as our EVP of Product Management. Beyond leadership, we've been hiring and training more engineers and scaling our team faster than ever before, resulting in a substantial increase in throughput and innovation. That team has been hard at work, and over the last quarter, we've been building out a new software delivery engine, leveraging a blend of our own robust cloud infrastructure and increasingly public cloud from both Amazon and Google. This new engine that we're building is built on the latest PaaS technologies. That stands for platform as a service. Some of these only recently available, which enables us to continue to press our advantage and stay ahead of other cloud contact center vendors who rely on architectures built before this latest wave of technology advancements was available.
Our team has been demonstrating industry technology leadership, most recently leading a collaboration with Google, Cisco, Comcast, and FreeSWITCH on a standards body submission to drive the industry forward. With this new patent-pending technology, we're aiming to make it dramatically easier for consumers to reach an agent by bringing voice calls right from the web browser all the way to the contact center without a phone in the middle, accelerating WebRTC adoption and improving customer experience. On the AI front, we've shared the treasure trove of data we have access to, with 5 billion minutes of customer conversations going through our platform annually. Our AI roadmap has now been validated by our largest and most advanced customers, and we have begun implementation, hiring, coding, and performing AI model evaluation and performance tuning. While it's early days in this market, we are certainly leading the way.
As we mentioned last quarter, we were featured on stage at Google Cloud Next as part of their partnership with Salesforce, a demo that was only possible due to the new delivery engine that I mentioned earlier. That's product. The third pillar is our go-to-market engine, and our results here convincingly demonstrate that our team, led by Dan Burkland, is one of the best in the industry, and we are making progress in this team on multiple fronts. First, the sales team continues to grow and scale. The average tenure of our leadership team continues to increase and is now nearly six years. We're rapidly adding capacity to our field salespeople, which we call sales directors. Next, we announced this quarter the strategic decision to meaningfully and rapidly step up our channel development, opening up a new avenue of long-term domestic and international growth.
We announced new leadership and we have new partnerships. On the leadership front, we hired a vice president and general manager of international sales based in London. Second, a vice president of global channels. Third, a new vice president of professional services. Each of these new hires formerly held leadership positions at large contact center technology companies and will be reporting to Andy Dignan, our SVP of global channels and services, who most recently led go-to-market globally for the collaboration business at Cisco. On the partnership front, we continue to gain traction with system integrators like Deloitte, Accenture, EY, Slalom, and IBM, adding people dedicated to the SI channel. These SIs are becoming a meaningful portion of our revenue as they're often brought in to help enterprises with their digital transformation strategy.
Earlier this quarter at Microsoft Inspire event, we announced a brand-new partnership with Microsoft Teams UC. We met with their partners and global sales organization to develop a joint go-to-market strategy. We're building a tightly integrated contact center solution with Microsoft, which gives their partners a huge opportunity to make further progress in UC and enter into the cloud contact center market. On the CRM front, we continue to have an excellent partnership with Microsoft Dynamics CRM. Finally, the anchor of our go-to-market machine is our customer success and professional services organization. The contact center is at the heart of the customer service technology landscape and is tied into many business systems. The customers need help managing that complexity, and to help them on that journey, we've built one of the largest and most highly rated customer success and professional services organizations in the industry.
These teams deliver rapid, differentiated, and on-site enterprise implementation with the high touch experience that customers really need. These engagements, along with our rock-solid platform, build trust with our customers, which in turn is what drives our DBRR, which on a blended basis was again 107% in Q2. This large experience, long tenured team of seasoned customer-facing experts is a key ingredient in the secret sauce that makes Five9 so successful. We believe no one else in the industry has anywhere near this level of customer-facing expertise, and we believe it will take years to begin to replicate. In conclusion, the stars have clearly aligned for Five9. All three pillars for success are in place. The market is heating up.
We have the right product at the right time and a leading go-to-market machine, and most importantly, a fantastic team of employees who, by the way, voted Five9 as one of the top 25 cloud companies to work for. To expand on our financial performance and guidance, I'll now turn the call over to our CFO, Barry Zwarenstein. Before I do so, I want to take a moment to acknowledge Barry, who was recently honored as the 2019 Bay Area CFO of the Year for small and medium public companies. Take it away, Barry.
Thank you, Rowan. Before going into specifics, a reminder that unless otherwise indicated, all financial figures I will discuss are non-GAAP. Reconciliations from GAAP to non-GAAP results are included in the appendix to our investor presentation on our website. We are very pleased with our performance, with both top and bottom-line results exceeding our expectations. Revenue grew 27% year-over-year and 4% sequentially, driven primarily by our enterprise business, which now makes up 79% of LTM revenue. Enterprise subscription revenue continued its multi-year performance of growing in the 30s, posting growth of 36% on an LTM basis. This enterprise business is highly profitable, generating a 6 to 1 LTV to CAC ratio on a truncated five-year basis. Our commercial business, which represents the other 21% of LTM revenue, grew in the single digits.
We expect continued single-digit commercial revenue growth now that we have lapped the easier 2017 compare. Recurring revenue accounted for 92% of our revenue. The other 8% of our revenue was comprised of professional services. Second quarter adjusted gross margins were 65%, an increase of approximately 120 basis points year-over-year. Second quarter adjusted EBITDA was $14.4 million, representing an 18.6% margin, an increase of approximately 270 basis points year-over-year, demonstrating the profitability of our business model. Second quarter non-GAAP net income was $12.3 million, a year-over-year increase of $5.4 million. Finally, before turning to guidance, some balance sheet and cash flow highlights. DSO for the second quarter was 30 days. Our operating cash flow for the second quarter was $6.8 million, a year-over-year improvement of $1.1 million.
We are optimistic about our potential for continuing cash generation, given our long-term model, our substantial NOLs, and our low DSOs. I'd like to finish today's prepared remarks with a brief discussion of our expectations for the full year and the third quarter of 2019. For 2019, we expect revenue to be in the range of $312.5 million-$314.5 million. GAAP net loss is expected to be in the range of $12 million-$10 million, or $0.20-$0.16 per basic share. Non-GAAP net income is expected to be in the range of $44.7 million-$46.7 million, or $0.70-$0.73 per diluted share.
Consistent with our previous discussions, this bottom-line guidance reflects expected increases in various growth initiatives, particularly in R&D and in go-to-market, to go after this massive market opportunity that is coming towards us. For the third quarter of 2019, we expect revenue in the range of $78 million to $79 million. GAAP net loss is expected to be in the range of $6.3 million to $5.3 million or $0.10 to $0.09 per basic share. Non-GAAP net income is expected to be in the range of $8.8 million to $9.8 million or $0.14 to $0.15 per diluted share. Note that a number of new hires were back-end loaded in the second quarter, and therefore, we expect meaningful uptick in R&D and in sales and marketing spend in the third quarter of 2019. Nonetheless, in the fourth quarter, we expect to again be reporting 20%+ adjusted EBITDA margin.
For modeling purposes, we would like to provide the following additional information. For calculating EPS, we expect our diluted shares to be 64.5 million and basic shares to be 61.5 million for the third quarter of 2019, and 64.2 million and 61.1 million respectively for the full year 2019. We expect our taxes, which relate mainly to foreign subsidiaries, to be approximately $75,000 for the third quarter of 2019 and $130,000 for the full year 2019. Our capital expenditures for the third quarter of 2019 are expected to total approximately $6.5 million-$7.5 million. For the full year 2019, we expect to continue capital expenditures to be between $20 million and $24 million. In summary, we are pleased with our second quarter performance, driven by the strong revenue growth and excellent unit economics.
The importance of customer engagement continues to be a key driver, and Five9 continues to execute extremely well against this massive opportunity. Operator, please go ahead.
Thank you. Ladies and gentlemen, to ask a question, please signal by pressing *1 on your telephone keypad. If you're using a speakerphone, please make sure your mute function is turned off to allow your signal to reach our equipment. Once again, press *1. We'll take our first question from Terrell Tillman with SunTrust Robinson Humphrey. Please go ahead.
Hey, good afternoon. Can you hear me okay?
Yes, Terry, we can. Thanks.
No, thank you. Rowan, I really like that statement or the pronouncement you made about the 30% plus growth in enterprise over a long-term basis, and I wanted to focus on that in terms of, you could see obviously a lot more than we can see. Maybe you could just give us some of the confidence foundational elements on that statement of 30% plus growth on the enterprise side as it relates to maybe the quality of the hires as it relates to sales reps, or how much you've expanded it in terms of that gives you great sales coverage. Just some more on what we really can't see on the outside, which is just the sales team and the go-to-market overall. Where is this confidence coming from? Thank you.
Thanks, Terry. It starts with the market, really. The fact is that this market is huge, right? Customer interactions are absolutely exploding. If you look at Gartner's data, that shows that over the five-year period that we're in, ending by 2022, the interactions in the contact centers are going up by 3.5 times. You have that's sort of underpinning the fact that the contact center is emerging as a strategic priority for businesses all over the world. That was reflected most recently in Morgan Stanley's analysis, where they looked at cloud buying patterns and the fact that customer experience was the top priority for CIOs and other C-levels. You have the fact that we've essentially gotten through the evangelism phase on the cloud. In other words, customers need to upgrade.
It's becoming an increasing strategic priority for their business, and they're convinced that the cloud is the way to go. Gartner, I think I pointed out in the call that Gartner doesn't even have a Magic Quadrant for on-premises contact centers. That's the first thing, $24 billion market, cloud penetration is beginning. The second thing is really about execution and scale, right? We have proven that we can execute on the sales front. We've proven we can execute on the product front. We've got the product that's winning in the market today and scale. The growth you're seeing driven today in the top line is really coming from that enterprise business. We're signing larger and larger deals. We're now highlighting those $1 million deals for you guys. We're seeing that traction. We're seeing the proven execution.
Frankly, in this market right now from a competition perspective, it's really a duopoly. Us and inContact are at the head of this market. That's, of course, in the Gartner report, but we see it in our win-loss, and we see them in the market. While there's noise in the market with new entrants and so on, none of them have a beachhead, and we're definitely not seeing them in the market. Therefore, my conclusion is that this 30s level of growth in the subscription of enterprise business is going to be durable over a long period of time.
Okay. Thanks for that. I guess my follow-up, though, kind of focusing again on go-to-market is also as you look at what you've assembled so far year to date, how do you and Dan feel about the sales capacity you have to execute against your targets this year and really even going into next year, and how much do these emerging global SI relationships play in that as well?
Yeah.
Thank you. Congrats.
Yeah, I'll turn to Dan, but just the intro is, look, we are super happy with the hires we've made. We've had a very stable team with very low attrition rates. The leadership team's been on average around for six years. If you look at the new hires that we just announced running channel and international, Dan and I and the team met with them. These are extremely high-quality candidates. We're attracting the top talent in the industry into these leadership roles. Frankly, getting into channel and international is going to be a big growth opportunity for the company. Attracting people who have done that before and have those relationships is absolutely huge. Dan?
Just to add to that, well said, Rowan. When you look at us bolstering the leadership team with those additional adds, we're preparing ourselves to now go from $300 million to $1 billion. In order to do so, we're going to rely on global channels, the prominent partnerships, but also continuing to really go to market with the best talent. Bringing in expertise, we've got a great management team that, as Rowan said, has been here for six years plus. We're adding to that in the areas of international channels, working with SIs and being able to leverage those relationships that they've had in their past. Folks that come in with the experience of having been there and done that from the $300 million on up is very important to continue our scaling.
Thanks, Terry.
We'll take our next question from Meta Marshall with Morgan Stanley. Please go ahead.
Great. Thanks, guys. Congratulations on the quarter. Just if you could kind of speak a little bit more about kind of the SI channel and you had mentioned that being an important kind of relationship to ramp, but just how long do you think it'll take for those partners to kind of get those businesses running? What type of investment it'll take from your part just to kind of maximize that channel? Second, just any update on kind of some of the trials that are taking place on the AI front would be helpful. That's it for me. Thanks.
Sure. Thanks, Meta. Great question. Along the SI front, let me be clear, it's not how long will it take to get traction and get that going. We've had partnerships for several years. The one large one, the global one is Deloitte, that we've had a partnership for about four years now, and we saw what occurred there and how much they were able to generate for us. They get hired along with the other SIs that we mentioned earlier, the Slaloms, IBM, EY, and Accenture and others, that are being brought into these larger enterprises to help them with their digital transformation strategy and how they should go about moving to the cloud in particular. We get access with them as part of that larger project and get brought in by them.
I think we mentioned on the last quarter call that Deloitte's been generating and is now generating well into the double-digit millions of dollars of revenue for us. We're now replicating that same model across those other partners that I just mentioned. We've applied resources and dedicated resources to working with them. It's just another way for us to expand our footprint, expand our reach, and get access up market. That's been working extremely well for us, and it's very strategic. You asked the second part of your question was with regards to-
AI
AI. I'll turn it to Rowan to let him answer that piece.
Yeah. Meta, that's going well. We've gotten a lot of great input from our customers who have helped us really clarify exactly where they want us to focus. That's around agent assist. That's the concept of the real-time AI recommendations and predictions that are sharing with a live agent on an actual call or messaging thread. We've actually now narrowed in on the definition of the product and a roadmap. We've also recently signed up four of our largest customers to become beta customers on this. It's currently in development and it'll be included in one of our upcoming releases, probably in 2020.
Great. Thank you, guys.
We'll take our next question from Raimo Lenschow with Barclays. Please go ahead.
Hey, congrats from me as well. That's amazing. The first question is, as you think about the $300 million going to $1 billion, a big part of a typical company build out there would be international. You touched on it a little bit, but I just wanted to find out more, like, are there kind of fundamental differences to this market? I know you're building it out, but is there, because you've seen a lot of adoption in the U.S., but slightly less internationally. I just try to understand that. Very congrats on that win. On that note, can you talk a little bit on the gross margins because Q2 65% is, I think, is the highest number I've seen ever in my model. Just a couple of comments on the strength there. Thank you.
Yep. Thanks, Raimo. I'll talk about the international. The traction we're seeing there is not a function of the market in so much as it is just our investment and the fact that we've talked about in the past that it's a huge market in the U.S. and we've really been focused there. As we've started to expand internationally, we see tremendous opportunity. That's why we just hired a new general manager for that business. Structurally, there are some differences in Europe. Obviously, it's a much more fragmented market. The U.S. is much more consolidated. The service providers are much more important in Europe. We'll have a different approach there. Fundamentally, it's a massive opportunity in Europe for us to get started on.
The person that we hired has actually built the contact center business for the market leader, and so we have brought in someone who has that expertise, has the relationships, and it is a really important dynamic there that you have the relationships and that you're on the ground in the country. It's a big move for us. It will require ongoing investment, and that's something that we'll be making over time, but we think we can make the investment as the business scales.
Raimo, with respect to the gross margin, yeah, 65 was one of our highest. Actually, in Q4 2018, we were 65.1. We're actually prouder or happier with this quarter simply because it's very revenue dependent. Q4 is a strong revenue quarter. Q2 is our toughest revenue quarter, and yet we managed to come within spitting distance of the all-time record. The biggest driver for that is our subscription business, which should not surprise you. That is, after all, of our recurring revenue, 92% is the total, 73% of the total. This is what we've been talking about, Raimo, for quite some time. It's the simple mechanics of the subscription revenue driven by the enterprise with the LTM 36% growth rate growing faster than our cost of subscription revenue.
That was taken those margins from the 60s years ago solidly now into the 70s, and a steady way with that durable growth that Rowan talked about into the 80s over time.
Okay, perfect. Well done. Congrats.
We'll take our next question from Sterling Auty with J.P. Morgan. Please go ahead.
Hey, guys. This is Sahil on for Sterling Auty. Congratulations on the quarter. A couple of questions. How would you say the contribution of new versus existing customers was in the quarter? We saw a couple of changes in management ranks. Are all the positions filled now, or are there any other changes that we might expect soon?
Just overall on the management ranks, no other changes. We hired our last executive level reporting to me. That was Anand Chandrasekaran from Facebook, who worked on the Messenger platform there. Now Dan has hired the key set of leaders to drive channels in international. Dan?
Yeah. To answer your question about new business versus existing, yeah, when I mentioned the net new bookings for enterprise was an all-time high by far. We don't disclose bookings, as you know, but that was clearly the case. We continue to get expansions, land and expand opportunities from our base. That's most well reflected in our dollar-based retention rates, which again, we're at 107% on an LTM basis. Very healthy business from both new and existing. Yeah, the leadership team on the go-to-market has just gotten larger and more robust and with better experience. I've never been as optimistic about the management team that we've assembled here on the go-to-market side to be able to take us to the next level.
Great. Thank you.
Yep.
Our next question will come from Scott Berg with Needham & Company. Please go ahead.
Hi, everyone. Congrats on a good quarter. I guess two brief ones for me. First of all, Dan, on the contribution from partners, you mentioned it was 60+% in the quarter. I think that's better than the historical trend of better than 55%. What's the right mix of that going forward with kind of these new partnership initiatives?
Yeah. We have such a plethora of partners that cross over many different industries. Some are directly tied in complementary integrations to ours, like Salesforce and Oracle and the other CRM providers. Some are go-to-market partners that are more on the bringing us into opportunities and expanding our reach. They're so different. Some are technology, some are ISV partners that do an add-on to the solution. Some are true resellers of the solution. It kind of runs the gamut. What we do is we look at those and say, "Where is there a partner involved?" That percentage is, I think, at a very ideal and healthy mark. Sure, we have our own marketing efforts and our own ability to go reach and find new customers and find prospects, but we also rely on that partner ecosystem to find them for us.
That brings our cost of acquisition down, especially as we continue to not only build trust within those partners, but also build reference ability within the customers that they've referred us to. Once we get those references speaking highly, those partners want more and more to recommend Five9 because they trust we're going to deliver for them. It's oftentimes their reputation that's on the line. It's their word that's on the line, and they want to know that who they recommend is somebody they can trust.
Got it. Helpful. My follow-up is for Barry. The percentage of revenues coming from non-recurring was 8% in the quarter. I think that's a little bit higher than the historical trend that I believe is closer to 5%, not looking at my model at the moment. With the even larger movement upmarket with some of these really large million-dollar-plus contracts, are you just finding that you need some more services work there to maybe shift that mix slightly, or should that maybe trend back towards the 5% I'm thinking about?
Yeah. Scott, the trend has been upwards. When we went public five years ago, it was 3%. Most recently it was 7%, now it's 8%. The trend is definitely to continue. I see Dan sitting next to me. We're not on video, but he's nodding his head vigorously, and he's been successful in bringing value to those implementations. We're talking about something that's mission-critical, and people want to be sure that the 6-step implementation process that the team has that go on-site for every enterprise implementation is properly appreciated and remunerated. Dan, you want to add anything?
Sure. Our ability to directly go in and provide these implementations with a very high touch model, Gartner recognizes that as one of our key strengths and differentiators. Enterprise customers require and expect that you're going to come in and very acutely do your research to figure out and design, do your discovery, do your design, your testing, your training, turning them up and then optimizing the system. All those services are so key to getting the customer off on the right foot and having them be able to truly take advantage and accomplish the business needs with the solution. There's nothing more important than that services business, we're seeing that more and more as we move further up market.
I just want to add one last thing, Scott, this is really going back to the earlier question on gross margins. I didn't mention at the time because it's not as material, but it's a gentle tell breeze in that many years ago, we used to have triple-digit negative margins. A result of the improved pricing from Dan and the percentage of the ACV that goes to the one time, those have now steadily improved. Now for the first time, it was a negative in the teens. I believe we can confidently talk about that eventually getting to breakeven and positive with a resulting overall corporate benefit.
Dan, super helpful. Congrats on this quarter. Thanks again, guys.
Thanks, Scott.
Our next question will come from Matt VanVliet with Stifel. Please go ahead.
Yes, thanks for taking my question. I guess as you look at some of the discussions around the partners, and how they can really sort of broaden your reach within customers by offering a better solution and help with the digital transformations, curious how you're thinking about maybe the total wallet share that you currently have with your existing customers and what that long-term opportunity might look like over the next three to five years.
Yeah. We've been seeing a fairly steady rise in our average revenue per user over time, over the time that we've been public. That's something that we see continuing. We've been very successful at selling more. As we move up market, the appetite to buy more in this space is higher. We end up in a really good place as we get these larger and larger customers. Specifically, our partnership with Verint has been going very well, where we sell Five9 WFO powered by Verint. We also increasingly see, and this is where I think the channel comes in and notably the SIs, but the desire of our larger enterprise customers to spend more time integrating the contact center deeply in with their CRM platform is there. That drives services revenue, it drives technology revenue.
Things like MuleSoft and so on are certainly part of that story. Workflow automation and so on. There's just a tremendous amount of touch points, and we see I can't probably directly answer your question around wallet share, but I can say that the overall wallet and pie is growing, and it's growing fairly rapidly. Our access to it, and frankly, our buyers' influence over it is also growing.
Thanks. Barry, as a follow-up, there was a mention earlier about using more of the public cloud resources out there. Obviously, it seems like it's probably for some incremental services, overall, just curious on how that might impact gross margins in the long run, if that doesn't continue to be a larger mix of the infrastructure used overall.
Yeah. Matt, frankly, our motivation on the public cloud underway is not done for margin improvements, though we understand that other companies have benefited from it. We're doing it much more for the nimbleness and the access to the various Platform as a Service advances that we can bring to bear. We haven't been assuming anything material, but it's certainly something that could be positive.
Great. Thank you.
Our next question will come from Jeff Van Rhee with Craig-Hallum Capital Group. Please go ahead.
Great. Hey, guys, this is Rudy on for Jeff. Couple from me. A lot of color on partners. I like it. With the partners, with respect to the actual deploys and implementations, what % of the overall implementations are being done by the partners? Secondly, a lot of people have some concerns with attrition in Salesforce right now. I think you answered this earlier, but I might have missed it. Could you just comment on any changes you've seen in the pace of attrition in Salesforce as well? Thanks.
Sure. Thanks, Rudy. This is Dan. Happy to take that. Looking at implementations by partners. I've been very cautious. While we're signing up some large global companies that are willing to make the investments necessary to be able to put in the quality implementation and have it result in success on the customer side, it's something that we're very cautious about. We've seen folks in the cloud, in our space that have had cloud offerings that have pushed out that responsibility to the channels prematurely, and the channel wasn't prepared or ready to be able to go as deep and as thorough as we can ourselves.
As we're signing up and enabling and going deeper with some of these larger partners, we are very cautious in requiring them to allow them to do OJT over-the-shoulder shadowing of our people to ensure that they, A, take the time to invest the right resources and the time and energy to be able to do the same quality that we could deliver ourselves. For us to monitor and over-the-shoulder on their first implementations. Only then will we actually relinquish and allow them to go the full route. There's very few doing that. We have some that are committed to doing that, and we'll get them trained up over the next several quarters. Again, I'm going to be very cautious because I want to make sure our quality does not degrade whatsoever. That's been a key part of our success.
As far as attrition on the sales front, we have extremely low attrition in the industry. I would put it up against anybody, especially the case for voluntary attrition. Like any organization our size that's growing, you're going to have some folks leave from time to time. Typically, it's either a mutual decision or it's one where we've kind of pushed them out the door to move on. Been extremely low across the board, and that goes for the last four or five years.
Great. Got it. Just one last quick one, if I could. Competitive landscape. Have you guys been seeing Unified Communications players, any increase in the frequency that you guys are seeing them in deals?
I mentioned earlier, this market is really a duopoly at this point. We share our win rates, and it is really inContact and Five9 tend to be in all these big deals. We really haven't seen any real material shift in the competitive landscape on that front.
We'll take our next question from David Hynes with Canaccord. Please go ahead.
Hey, thanks, guys. Nice quarter. The question earlier was asked on public cloud as it relates to the financials. Maybe, Rowan, you could talk on, you hit on a new software delivery engine in your prepared remarks. Just curious, how does that leverage public cloud? Should we think of it as more for international opportunities? What does it do for the product? Any additional color there would be helpful.
Yeah, no, it's actually our engine and technology architecture for our future development is going to be public cloud-based or is public cloud-based. It's not exclusively for international expansion, although that's certainly one benefit. It's more about acceleration and leveraging the massive amount of services that are available in the public cloud today. Five years ago, if you were to build a SaaS service, you would have to deploy. It was not necessarily a clean-cut case to go public cloud because you could leverage open source in your own data center and potentially get better economics. That's really increasingly not the case as Google and Amazon and Microsoft have fleshed out their PaaS layers. That's providing us with leverage on our R&D. It's all about leverage, really.
Yeah.
We talked about increasing the spend in R&D, all of the new capabilities that we are driving, we're really driving towards public cloud. Our AI offer we talked about earlier will be launched on public cloud, many of the new offers that we are bringing to market will be public cloud sort of hosted. Now, we continue to leverage our own cloud infrastructure that we host in our own data centers and colos around the world. There is some benefit there around leveraging the investment we've made as well as the network that we've built up and so on. Our future development and platform is really public cloud-oriented.
Yep. Okay. A follow-up. As you get further into these pilots with AI and the agent assist technologies, how are you thinking about price exploration? Have you figured out what customers may be willing to pay, and any color you could share with us there?
Too soon to tell.
Yeah.
We'll keep you posted though on pricing.
Okay.
Yeah.
Very good. Thanks, guys. Nice quarter.
Thanks. You too.
We'll take our next question from Brent Bracelin with KeyBanc Capital Markets. Please go ahead.
Hey, Brent. You there?
Caller, please check your mute function. With no response, we'll move to our next caller, Jonathan Kees with Summit Insights Group. Please go ahead.
Great. I'm off mute. I want to gradually add my kudos to the congratulations for the quarter and to Barry Zwarenstein. I have a couple topics I would like to ask about. They should go pretty quickly. One, regarding the press release and also the commentary during the call about the partnership with Microsoft in go-to-market and product collaboration. Just curious, does this mean that they are going to be selling your product to their customers, or is it still going to be mainly Five9? Taking a step back, how much of a needle mover is that, first off?
Yeah. Great question, Jonathan. This is Dan. It's a little premature to know the impact of the needle, if you will, if it's going to move the needle and how much. It is a two-way partnership. They will be partnering very closely with us and helping introduce us into their partner and their go-to-market channels to be able to provide Five9 as a contact center solution to go on top of the Teams products that those channels already sell. One of the dilemmas is their channels are out selling Microsoft Teams. It's without contact center. Doesn't have contact center. That hinders your ability to get into certain enterprises that do want to do a full reset, as well as going into their existing customer base that uses Teams and being able to provide contact center.
We see them bringing us more incremental than the other way around. Then, your other question.
The other topic. Yeah. It sounds like a lot of great potential there. The other thing I want to ask about is, regarding the new hire from Facebook. I guess, Rowan, you have pretty fairly predictable MO so far of hiring executives, seasoned executives with specific expertise to come over to Five9 and continue that expertise work. Just curious, this senior hire that you brought in has replaced an existing exec you have in product management and development in contact center. This person who's coming in has messaging and e-commerce background. Rowan, just curious if you can share some light in terms of your product development, roadmap-
Yeah
Beyond AI and AWS and bring in place.
Yep
features you've talked about ad nauseam. Just any new stuff there? Thank you.
I hope you're not tired of it, because I'm going to keep going.
No. By all means, yes, please.
Anand worked at Facebook on the Messenger for Business platform, and the Messenger for Business platform was really targeted at businesses that wanted to engage with their customers through the Facebook Messenger platform. That's obviously a huge draw for businesses, and so many large businesses in the U.S. were engaging with Facebook on that front, and Anand was at the front end of that. I'll speak for Anand here, but the idea here is that customer interactions are exploding across all of the new channels. That's what's driving the CX really up to the top of the priority stack, as Morgan Stanley reported recently, that customer interactions are on the rise. Gartner says they're going to go up three and a half times in the next four years, over a five-year period that ends in 2022.
The customers want to incorporate those new channels into their contact centers, and we felt that bringing Anand in gave us an incredible perspective because he was at the vanguard of messaging for business at Facebook. He's got a powerful vision of the contact center, given his time at Facebook, and he had a chance to interact with a lot of enterprise contact centers and ISVs who were building technology in that space. When Anand and I first met, he really explained his vision around the enterprise contact center business as a huge area of future growth and technology innovation. That's what he was seeing from his lens over there.
From our perspective, we got to have someone who reflected the next generation of preferences, of users in terms of how they want to call in, how they want to connect or get help through messaging and so forth. That really helps us paint a vision. I think Anand's going to help us paint a vision for the future and take us into the future of the contact center. Very, very excited about him joining.
Sounds like he can really help out. Great. Thank you so much.
Yeah.
Good luck, guys.
Thanks, Jonathan.
Thank you.
There are no further questions at this time. I'd like to turn the call back over to management for any additional or closing remarks.
Thanks, operator. In closing, I'm pleased with our strong first half performance. We're making excellent progress on our strategic priorities, led by our increased investments in product innovation and go-to-market. We have a fantastic team in place. There's tremendous opportunity here for Five9, and we look forward to sharing our ongoing progress at our upcoming Analyst Day in New York on November 12th. Please join us there. With that, we'd like to thank everyone and wish you a good day.
