As a reminder, this conference is being recorded. I would now like to turn the conference over to your host, Annie Rosenberg. Thank you, and over to you, ma'am.
Thank you, operator. During this call, we will make forward-looking statements related to our business, including statements related to the expected performance of our business, future financial results, strategy, the potential impacts of the COVID-19 pandemic and associated global economic uncertainty, long-term growth and overall future prospects. These statements are subject to known and unknown risks, uncertainties, and assumptions that could cause actual results to differ materially from those projected or implied during the call. Actual results and the timing of certain events may differ materially from the results or timing predicted or implied by such forward-looking statements, and reported results should not be considered as an indication of future performance.
Please review our filings with the SEC, including our final prospectus and the section entitled Risk Factors therein, filed with the SEC on May 12, 2021, for a discussion of the factors that could cause our results to differ. Also, note that forward-looking statements on this call are based on information available as of today's date. We disclaim any obligation to update any forward-looking statements except as required by law.

We use these non-GAAP financial measures internally to facilitate analysis of our financial and business trends and for internal planning and forecasting purposes.
We believe these non-GAAP financial measures, when taken collectively, may be helpful to investors because they provide consistency and comparability with past financial performance by excluding certain items that may not be indicative of our business results of operations or outlooks.

With that, I will turn the call over to Or Offer, CEO of Similarweb.
Thank you, Annie, and thank you all for joining us here today for our Q4 2021 earnings call. It's great to be here with all of us this morning. We finished off a very strong 2021 with excellent performance in Q4. GAAP revenue grew 51% year-over-year to $40.2 million, exceeding our guidance for the quarter. I am very proud of our team for continuing to execute well and accelerating our growth. During today's call, our CFO, Jason, and I will provide more details around our Q4 and 2021 results and provide Q1 and full-year guidance for 2022. Let's discuss the results. In many ways, 2021 was a game-changing year for us. Most importantly, our growth trajectory has changed. In 2021, our total revenue grew by 47% to $137.7 million.
That represent an increase of 15 percentage points of growth over last year, that was 32%. We ended this year with $165 million in ARR, concluding our third straight year of accelerating ARR growth. As we move into 2020, we are seeing very strong tailwind for the business, an increasing term and rapidly expanding demand for our solution. In light of those favorable condition, we will continue to invest across the business in order to further nourish and grow our customer base, as well as strengthen our product portfolio and data assets. The strength of our customer base has also improved. In 2021, our most significant growth come from our largest and most strategic customer segment, those companies that generate more than $100,000 in ARR.
We grew the total number of those customers by 45%, and together they now represent more than 51% of our total ARR. Overall, we more than double our rate of new customer acquisition versus 2020. We continue to see our customer growth being driven from a diverse set of industries. In 2021, the new logos we added, including amazing global brands like Fiat Chrysler, Intel, 3M, Mondelez, DoorDash, Tesco, CVS Health, and many more. Our customers are more engaged with our solution and more committed to them than ever before. 33% of our ARR is generated from our customers signed to multi-year contracts. This is an 8 percentage point increase from the 25% of ARR last year. Even more significantly, we have increased our customers total lifetime value, with NRR hitting an all-time high.
We closed Q4 with overall NRR at 113%. It's 125% for the critical $100,000 ARR customer segment, both a 12 percentage point improvement over our Q4 2020 numbers. I want to pause here for a second to reflect on what I see as the most important market driver for our business growth. We believe that today the number one mission for every CEO and business leader is to drive growth. The biggest growth opportunities come from the digital world, a place without borders, where it's possible to almost instantly reach and sell to audience at a global scale. In this world, where growth potential is almost unlimited, data is king. To see and capture the growth opportunities, every company is looking for better market data.
They need a complete picture of what's happening in their markets to answer the most strategic growth questions like, how do I grow my demand? How do I grow my product portfolio? How do I grow my market share? How do I grow my audience, and how do I grow my sales? This is what Similarweb does. We give companies visibility they don't have, an insight that guides them to what to do next in order to grow. We believe our proprietary data and growth insight give our customer an advantage in their markets. We believe the value we deliver is outstanding, and that every company that wants to compete and win in the digital world need us. This is why we see a huge TAM and potential for high growth for many years to come.
In 2021, to accelerate our own growth rate, we expanded and improved our product portfolio. In Q2, we launched our Shopper Intelligence solution, and by Q3 we already signed our first seven-figure deal to this product. Shopper Intelligence is highly differentiated solution that give our customer an amazing insight into consumer behavior within online marketplaces. In Q4, we expanded this offering significantly, improving our marketplace insight coverage by adding Walmart, Target, Best Buy, and Chewy on top of our existing support for Amazon Insights. Our goal is to become the market standard in this emerging space and to be an essential growth enabler for every CPG or retail company looking to do business in the online marketplaces. Within our customer base alone, we identified over 700 companies that meet our target profile. The opportunity for this product is huge.
We'll continue to add major enhancements to our other offering as well. In Q4, we enhanced our Sales Intelligence solution by partnering with a leading data provider to add a contact database to our offering. That solution now bring together 400 million-plus contacts with digital traffic and engagement insights and technographic data. We believe this combination of data and insight is ideal for sales organization while targeting digital-first businesses such as e-commerce, publishing, payment, and digital advertising. Now, with just one Similarweb solution, sales representatives can identify qualified accounts, connect with the right decision-makers and influencers, and engage those prospects with a compelling pitch that leverage our proprietary digital insights. Finally, as you may have seen, I'm very excited about today's announcement of a new data licensing agreement with App Annie, a market leader in mobile app insights.
The agreement gives us access to an important set of App Annie mobile application data, which we will incorporate into our platform. We plan to launch a new offering based on the App Annie data and insights in Q2. By bringing together our respective best-in-class data, we believe Similarweb will be able to deliver an even more accurate, more comprehensive view of the digital world, a powerful offering that will improve the insights and competitive advantage we create for our customers. Of course, this means that companies will be able to purchase industry-leading web and mobile web app data and insights from a single source. We believe this will be a very compelling proposition in our markets and a game changer for companies looking to take a unified approach to optimizing their digital strategy across platforms.
In 2021, we also enhance and expand our product offering by completing two acquisitions, SimilarTech and Embee Mobile. Both transactions demonstrate our ability to execute on smart acquisition opportunities and improve our customer value. SimilarTech technographic data is now used across the board in almost every Similarweb product, from our free offering to solution like Sales Intelligence and Investor Intelligence to our API and data feeds. Embee Mobile, which was completed in Q4, has already been used to enhance our offering as well. For example, in Q4, we added a new feature to our Shopper Intelligence solution called Shopper Demographics. This feature enables e-commerce companies to get to know their audience on a deeper level, so they can inform new product development and optimize buyer campaigns.
Going beyond basic identifiers like age and gender, this new analysis segments every category and brand on Amazon according to education level, household size, and income, and employment status. We believe it is a highly different feature in the market, and it would not have been possible without data from Embee Mobile acquisition. Finally, in 2021, we continued to invest in our people, aggressively scaling our organization to support our growth. We expanded geographically in adding new offices in Munich and Northern Virginia, and we're working hard to build out our new Similarweb headquarters, which will be located in the center of Tel Aviv metropolitan area. When it's completed, we believe it will be a significant attraction that will help us to continue to recruit top talent here in Israel.
To summarize, we believe that 2021 was a pivotal year, and we are entering into 2022 with great momentum, including a track record of accelerating growth and growing market opportunities ahead of us. Back in May, we successfully completed our IPO on the New York Stock Exchange. Since then, we have delivered three consistent quarters of strong revenue growth, all north of 45% year-over-year growth, concluding this quarter with more than 50% year-over-year growth. Our story has improved materially since our IPO across all of our business. We continue to add and to improve our product portfolio and offering, both organically and inorganically, expanding our team where we are rapidly increasing our product value and stickiness, resulting in double-digit growth in our net revenue retention.
We believe our combination of consistently strong growth and solid gross margin positions us as a small group of best-in-class SaaS businesses. Most importantly, we are a leader in a large and high value market with a unique opportunity to become a critical growth driver for every company that want to compete and win in the digital world. I'm excited about our progress and opportunity we have going forward. We delivered a strong Q4, capping off a year of tremendous acceleration in our business. We are confident about our growth strategy and our ability to ultimately capture a large share of a very valuable market. I will now turn the call over to our CFO, Jason, to discuss more about our financial results and 2022 financial guidance. Jason?
Thank you, Or. Good morning, everyone. I will now walk you through our Q4 financial results before introducing our guidance for the Q1 and full year 2022. Total revenue for the Q4 of 2021 was $40.2 million, reflecting record 51% year-over-year growth. This increase was driven both by an increase in our total number of customers, which rose by 28% in Q4 to 3,487, also a record high for us, as well as an increase of 18% in our average revenue per customer to nearly $48,000 in Q4. For the full year 2021, total revenue was $137.7 million, reflecting 47% year-over-year growth.
Dollar-based net retention rate, or NRR, was 113% overall and was 125% for our greater than $100,000 ARR customer segment, an increase of 12 percentage points for each of those metrics compared to last year. As you know, substantially all of our revenue is annual recurring revenue, or ARR, with a minimum subscription term of one year. We continue to increase the number of our customers who commit to multi-year subscriptions. As of the end of Q4, 33% of our ARR is generated from customers with multi-year subscriptions, compared to 25% last year. This trend towards increasing contractual commitments, along with our high NRR, reaffirms the value our customers see in Similarweb and speaks to the increasing health and durability of our ARR.
Please note that unless otherwise stated, all references to our expenses and operating results are on a non-GAAP basis and are reconciled to the GAAP results in the earnings press release that was issued earlier today. Our gross profit totaled $30.2 million in the quarter, representing a gross margin of 75.1% versus 78.9% in Q4 2020. The decrease is primarily the result of the acquisition of Embee Mobile, which closed in Q4, whose fixed costs contributed to an increase in cost of revenue. Operating expenses grew to $48.5 million in Q4, up from $25.7 million in Q4 2020, largely reflecting the investment in personnel across the business to support our growth.
The specific components of our operating expenses were Research and Development, $12.8 million versus $6.2 million in Q4 2020. This increase was driven primarily by growth in employee headcount, particularly among employees focused on our newer solutions such as Shopper Intelligence, Sales Intelligence, and Investor Intelligence. As I discussed in Q3, we are already realizing revenue growth from these new solutions and believe that these investments will prove to be meaningful growth drivers in the future. Sales and Marketing was $26.6 million versus $15.4 million in Q4 2020, driven principally by increased investment in sales and account management headcount and marketing activities as we scale to build pipeline and support our plans for growth in 2022.
General and administrative, $9.1 million versus $4.2 million in Q4 2020, which includes $1.4 million of additional costs for the quarter that we now incur as a publicly traded company, as well as additional employee headcount required to support our growing operations globally. As a result, our non-GAAP operating loss for the quarter totaled $18.4 million, better than our guidance, compared to $4.7 million in Q4 2020. For the full year, our non-GAAP operating loss totaled $51.7 million, better than our guidance, compared to $14.9 million in 2020. Free cash flow for the quarter was - $11.5 million, compared to - $1.4 million in Q4 2020, primarily as the result of the investment in employee hiring to drive our growth.
These investments continue to show their value in the acceleration of ARR, customer growth, and higher NRR. Turning to the balance sheet, we ended Q4 2021 with $128.9 million in cash and cash equivalents and no debt. We believe that our cash balance and our $75 million credit facility, totaling $204 million of available funds, provides us with more than enough liquidity to execute on our growth plans and to take us to positive cash flow, which we plan to reach in 2024. Our deferred revenue increased 46% year-over-year to $78.8 million, compared to $53.9 million at the end of Q4 2020.
Our remaining performance obligations, or RPO, increased 60% year-over-year to $137.5 million, compared to $85.7 million at the end of Q4 2020. We expect to recognize approximately 88% of total RPO as revenue over the next 12 months, and we believe these metrics are a good indicator of the health of our business and our revenue streams. As a result of our strong performance over the last three quarters since completing our IPO, as well as the product innovation that we continue to deliver and the market opportunity that we see ahead of us, we are issuing strong guidance for Q1 and for the 2022 fiscal year.
For the Q1 of 2022, we expect total revenue in the range of $41.1 million-$41.5 million, representing 40% growth year-over-year at the midpoint. For the full year, we expect total revenue in the range of $193 million-$194 million, representing 41% growth year-over-year at the midpoint. Non-GAAP operating loss for the Q1 is expected to be in the range of $20.5 million-$20.9 million, and for the full year, between $83 million and $84 million.
This is driven by the investments we are making to continue our strong growth, as well as the investments we are making to further expand our data moats through strategic moves such as the acquisitions of SimilarTech and Embee Mobile, as well as the data licensing agreement with App Annie. This also includes negative impact due to foreign exchange movements, which we estimate at approximately $10 million of additional cost. In light of our strong unit economics and efficient land and expand model, which are reflected in our strong NRR, and in order to capitalize on our strong momentum and market opportunity, we expect to continue to make significant investments in the business through 2022 and 2023 as we execute on our plans to become cash flow positive on an ARR of between $450 million-$500 million in 2024.
As I mentioned, we are in a strong cash position and believe that our available funds provide us with more than enough liquidity to execute on our growth plan until we reach positive cash flow. To conclude, we've executed well since our IPO last year. Our business is performing extremely well across all of our major initiatives, and our financial results and guidance indicate that we're heading into 2022 with strong momentum. With that, Or and I are happy to take your questions. Operator?
Thank you. At this time we will be conducting a question and answer session. If you'd like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate will indicate your line is in question queue. You may press star two if you'd like to remove your question from the queue. For participants using speaker equipment, it maybe necessary to pick up your headset before pressing the star keys. One moment please, while we poll for questions. The first question comes from the line of Brent Thill with Jefferies. Please go ahead.
Hi, this is John Byun for Brent. Thanks for the question. Just two questions. First on the aggressive investment plan for 2022 that you're continuing, if you could go a little bit more detail as to where those things will be focused or prioritized, you know, across OpEx and other investment needs. Then in terms of the ARR for 2024, I mean, that looks like a pretty big growth. Just wondering how you're thinking about the bridge from, you know, last year's 165 to that number 2024. Thank you.
Thanks so much. As we mentioned in the first part of the call, we're seeing a great opportunity ahead of us. The momentum that we're seeing in the business in terms of both unit economics and the revenue growth is pretty big. We see the demand coming in. You're seeing, I think, the guidance that we're giving for the upcoming year, and we see that the opportunity that is ahead of us and the big TAM and our market position is not going away.
Great. Thank you.
Thank you. The next question comes from the line of Bhavan Suri with William Blair. Please go ahead.
Hey. Hey, Jason. Hey, Or. This is actually Arjun Bhatia for Bhavan Suri. Great quarter, guys. If I can ask on the App Annie partnership, can you just give us a sense for how the data assets that you're getting through App Annie differ from Embee Mobile? Are these going to be complementary in the new offering that you're planning to introduce in Q2 here? Or do they, you know, do they both end up feeding into that offering? Just help us understand the difference, how the data differs between the two assets there.
Hi. Of course, it's Or here. It's a great question. First of all, there is a major difference between Embee Mobile data to App Annie data. Embee Mobile data is based more on metered panel. When you have small sample of panel, but a lot of deep data about demographic, et cetera. One example that we discussed here in the earnings, how we're using this data to enrich our shopper solution, about what people are basically the demographic of people of buyers online. Also, Embee Mobile data is more deep you can see in app activity that's a little bit different than the data that App Annie is presenting. There is a major difference and different use case for those assets.
Perfect. Very, very helpful. I wanted to touch on large customer activity. It seems like the deal sizes are getting larger overall, and even amongst your largest customers, the deal sizes are getting larger. Can you maybe just give us a sense for where digital data and intelligence is on the investment priority list for enterprises today? I would love to understand, you know, this 2024 target that you've put out, where enterprise activity and large deals actually flow into how those flow into that, I think it's like a 40%-45% CAGR that you've implied in that 2024 target. Thank you.
Yeah. I think that, you know, as our offering is growing and, you know, we're improving our product, not only the access to the data, the insights we're pulling and our ability to, you know, train and teach our customer how to drive more ROI from the market data we provide, they see more ROI, and then the willingness to pay is go up. You know, if you think about Similarweb, for example, research solution five years ago to compare to what we're giving them today, you know, the ROI is dramatically bigger. You know, we're presenting more deep and more advanced software. It gives more ROI to the customer. He has ability to pay, then the willingness is go up. This is one element. Second is our transition as a company to multi-offering solution.
You know, historically, we used to land only with our research solution. Now we come into the enterprise, and we have this full suite of offering to them. You know, we land with the research, and then we have a nice solution for the marketing organization to help them drive more growth and ROI. We have another offering for the sales organization that we go and help them drive more growth, et cetera. I think all those combination together, it's what you see in the increased ACV. You know, that you see that growing very nicely over the past few years.
Okay. Thank you very much, and congrats again on a great Q4.
Thank you.
Thank you. The next question comes from the line of Sterling Auty with JP Morgan. Please go ahead.
Hi, this is Maya on for Sterling. Looking at the 75% gross margin during the quarter, is most of that coming from the App Annie licensing deal, and just how are you thinking about gross margin moving forward?
Yeah. I will answer part, and if Jason or Rami can also join. The App Annie deal will only go into now for this Q1. The gross margin you're seeing is for Q4, and it's mostly come from the acquisition of Embee Mobile we did that we need to integrate their data operation about managing a metered panel and the headcount involved. This acquisition was, you know, to strengthen our moat around our data moats. We are very bullish around that. I think all those move that we're doing to increase our data acquisition and building more moats about our uniqueness of our data is very, very strong, smart, strategic move. As the company grow, on their own, the long-term model will bring the company to the 80% gross margin that we're targeting. Th is is my thoughts around it. Jason, you want to add anything from your side?
Yeah. I think, like you said, Or, it's you know, the App Annie licensing agreement will only go into effect in 2022. Just as a reminder, most of the costs that we have in our cost of revenue is our fixed costs. Therefore, as we integrate you know, Embee Mobile and then see the revenue that comes in, we get a lot of leverage out of those fixed costs, both on the data side as well as on the personnel.
Okay, great. Just, if I can add a follow-up. Between now and those fiscal 2024 targets, do you see that 125% retention rate for the top bucket of customers, as a target retention rate between now and then?
Oh, of course not. We are only getting started, as I like to say.
Okay, great.
I think, like, we're excited about the performance that we've had this year and the transformation that you've been seeing from 2020 into 2021. We like the momentum. Like Or said, you know, there's a lot of business to be done over the next couple of years.
Great. Thank you.
Thank you. The next question comes from the line of Jason Helfstein with Oppenheimer. Please go ahead.
Hey, guys. Thanks. Just on Embee, because I think, you know, I'm not sure how much we will all have that factored into our gross margin for the quarter. I guess how fast, you know, would you expect the gross margin to recover as you scale those costs? I mean, again, like, by the end of this year, would the gross margins be back to historical levels? I guess on top of that, and maybe the answer is no, how are you thinking about the impact of App Annie this year on revenue, gross margins, and EBITDA? I guess, I don't think you did, but maybe opine on, you know, the deal, the timeline, the terms, why not buy them? Anything you want to share? Thanks.
Sure. Let me maybe I'll start with the financial questions that you had. I think that's exactly right. We're expecting to see gross margins start going back towards the end of the year, back to the same historical levels that you've seen. I think this is consistent with what we've done in the past. When you look back, you know, let's go back to 2018, 2019 and 2020, you saw gross margin go from 54% to 71% to 77% to 78% this year, as we added in additional data sets and increased our data moat and then leveraged that as we grew and accelerated our revenue. I think that's the same thing you'll see here. In terms of the impact of App Annie, the App Annie deal, all of that is baked into the guidance that we have given earlier today.
I guess I'm asking, like, if we wanted to think about how much of the guidance is App Annie versus not App Annie. Then Or could answer the other question. Thanks.
Yeah. We're feeling very comfortable with the guidance that we've given and are looking forward to a strong year.
Okay. Or, just any more color on, like, the length of the deal, the terms. Do the terms get more favorable over time if you sell more of it? Why not do, you know, why partner and not acquire?
I will try here to talk carefully because we have, you know, an agreement here with App Annie that I'm not hundred percent sure what we can disclose or not disclose, but the term is that it's a fixed price that we pay. This is a great motion. We have a really great relationship with the App Annie management and highly respect, and we're very excited that we're able to put in place this partnership together and strengthen the relationship. You know, start working together and time will tell.
Okay, thanks. I had to try.
Thank you. The next question comes from the line of Patrick Walravens with JMP Securities. Please go ahead.
Oh, great. Thank you. Congrats on the 51% growth, you guys. First of all, Jason, I emailed you about this during the quarter, but when I was using the product, which we do, in January, you know, there was a message that popped up that said, "We're having issues with the app analysis section. It began in January, and we expect to have it resolved sometime in February." Can you talk about what that was? W as that related to the App Annie data?
Yeah. I will talk about it. First, what happened is that it was a bug in our R&D team. One of them deploy a code in a Friday night that will create a bug and then cause a little bit of mess and just took them time to recover. They discovered after two days, and then until they fixed it. This is what around that is just very stupid mistake here. That's this thing has nothing to do with the App Annie deal, as you can probably think. This conversation relationship with App Annie has been going on for many many months and this dialogue, so there's no relation between those two.
Okay, great. Then Jason, can you maybe. If you look at the operating income or really operating loss guidance versus the street, it's for 2022, it's a $35 million delta. Can you bucket that for us? You know, a third this, a third that, or half this, half that, just roughly how does that $35 million break down?
Yeah. It's the bulk of that is what you will see in both our R&D and our sales and marketing, which is really focused on making the investments in order to, like I said, to really focus on growing the business. The thing that we've seen, we had the conviction when we started 2021 that we had hit an inflection point, that the business was solid. Remember at the end of 2020, we're effectively a cash flow breakeven business. We know how to manage a business that's cash flow breakeven.
What we saw in front of us was this, with this big TAM and this big opportunity, and what we're seeing today is strong, is those strong unit economics and the efficient land and expand model, which you're seeing in it ultimately in not only revenue growth, but the strong NRR. That's the proof put to us that our conviction was right, and therefore we are continuing to invest in order to grab the TAM that we see ahead of us. Like I would tell you is that, you know, we know where we're going. You'll see the breakdown.
You know, we could take offline and go through each line, but it's mostly focused on headcount and marketing activities to continue to grab that TAM. On the flip side, on the R&D and building out the data moats, it's the kinds of things that strengthen our product set that is the exact factor that drives that higher NRR, having more products and solutions to sell into our existing install base as well.
Okay. I know you mentioned, but can you just remind me what the FX, I mean, the shekel is super strong, right? That's the issue. Of that $35 million-
Right. Yeah, exactly.
Stays FX.
We said about $10 million of that is in FX.
Wow. Well, almost a third of the-
Yeah.
-of the-
Correct.
This is just FX. Okay. All right. Great.
Exactly. In the absence of an FX change, this would be an even stronger guidance as you pointed out.
Okay. Thank you.
Yes.
Thank you. The next question comes from the line of Ryan MacWilliams with Barclays. Please go ahead.
Thanks for taking the questions. I'm pleased to hear about the opportunity ahead for Similarweb. Or, you know, how can Similarweb benefit from Amazon retiring Alexa.com in May? Do you view this primarily as a source of new logo growth, or do you think this could be a meaningful revenue opportunity? Thanks.
I think it's a great thing for Similarweb in basically two elements. One, from traffic and awareness. Alexa.com, which was a website owned by Amazon, was a big source for ranking digital assets, and it was attracting, I think this website is attracting till today a few million visitors that will need to find a new home to get this ranking statistic, and they will come to us as we would be the only place to get this data. This is one, a lot of tofu, you know, awareness traffic that will come to us.
Second, I think there is a great amount of book of business that will look for a new home and a new alternative. I don't know how much to expect. I don't have the numbers. I you know, it was a decent business that ran for, I don't know, maybe 20, 25 years. I don't know exactly. I can assume you have a lot of customers, but I think Similarweb is the right place to come to get an alternative. I think we're going to have some benefit. I don't know how much.
Perfect. Then maybe for Jason, two-part question here: If you quantified what Embee Mobile meant for revs for this quarter and then into the guide for next year. You mentioned targeted investments to support new products. What does that investment look like for Shopper Intelligence to capitalize on the early momentum there? Thanks.
Hey, thanks, Ryan. So the Embee standalone contribution to Q4 of 2021 revenue was not meaningful. Was not material. Y ou know, one of the things that as Or mentioned and we talked about when we announced the acquisition last quarter was that the data moat that creates and the enhancements that it enables us to do on our existing solution set is pretty impactful. As Or mentioned in his remarks earlier, for example, we were able to enhance Shopper Intelligence and give now demographic data that we couldn't do before because now that we were able to leverage that data that we get from Embee Mobile.
We're pretty excited about what that does to all of our existing products, and the net retention that'll drive, that you'll see ongoing for the sales into the existing customer base, as well as new sales to new customers as well. The investments, on the investment side, like I said, we don't break down, you know, for one solution to another solution where the headcount is going. It's you know, we look at Shopper Intelligence as an example, as a very early days of their growth, of that product's growth. We for sure, you know, we'll see within the guidance that we've given today, some nice contribution from that product specifically.
Appreciate the color. Thanks, guys.
Thanks so much.
Thank you. The next question comes from the line of Tyler Radke with Citi. Please go ahead.
Hey, good morning. Thanks for taking the question. Wanted to ask you just about what you saw in the quarter in terms of, you know, seasonality. I think if I look at the net new ARR contribution, last year, Q4 was your biggest quarter. This year, it looks like Q3 came in ahead of Q4. Anything to call out from a seasonality perspective? Would you expect with accelerated sales and marketing investments that ARR growth should accelerate next year as well? Thank you.
Yeah. Hey, Tyler, thanks for the question. Yes, we're seeing, you know. Last year was an outstanding Q3. With this year, Q4 was great and really strong performance. A good end. You know, I think it exceeded all of our expectations, both what we had guided to and I think what you guys had expected. We're pretty proud of the results in Q4. More importantly, the momentum that we see going into this year, which is part of the guidance that we have updated and issued now for 2022.
I think that what we're already starting to see is favorable unit economics from the investments that we've already made in the sales and marketing teams that hopefully you guys are seeing in terms of both the revenue growth and the net retention numbers. I think the NRR numbers are, again, really outstanding. The customer growth and the other metrics that we talked about, when you look all across the board, the customer lifetime value of our customer base is going up.
Net retention is going up. Pricing is going up. Number of customers are going up. Number of customers who are expanding to being $100,000 customers or more are going up. That is now representing 51% of our overall revenue. When you look at that, we're feeling, you know, that we're seeing from where we sit, a really strong performance and ROI on those investments that we've made. We anticipate that we are going to continue to see that as part of our investment plan.
Thanks. Just a follow-up. I guess, as we think about your, you know, long-term guidance here in 2024, 2025, like, as you think about the, you know, investments you need to make on the data acquisition side, I mean, do you feel like with this App Annie partnership and Embee, you've completed the portfolio? You know, I guess what gives you the confidence that you can go out and make these margin, multi-year commitments given just the rapidly evolving landscape and obviously some of the investments that you've made recently? Thank you.
First of all, I think it's a good question. I think that, so from our side, thinking about data modeling with this move with Embee and App Annie and partnership, we fully cover everything around mobile aspect that I think we'll probably not going to have a lot of, you know, more expenses down the road to increase this area. I think around everything around data expenses, I think we're in a good place right now. I think looking that into the future, I don't think we increase it anymore. Jason, maybe you have anything to add there?
Yeah. I think, Tyler, one other thing that you were asking was about, like, where do we get the confidence to go into these multi-year, you know, investment agreements? I think that the other thing that was a big standout this quarter were two metrics. One is that today, 33% of our ARR is now, you know, contract under multi-year agreement. It's not only cost to some degree, but it also a third of our ARR is already contracted on multi-year agreement. You see that not only that, but you see it also in the 60% growth in the RPO. We have, to some degree, a great visibility into the revenue that we see going forward. That gave us the confidence that we need in order to raise the Street's expectations as to what we think Q1 as well as the full year of 2022 will look like.
Thank you.
Thank you. Ladies and gentlemen, we have reached the end of question and answer session, and I would like to turn the call back to Or Offer, Co-Founder and CEO for closing remarks. Thank you.
Thank you, everyone. I really appreciate you coming and spending the time. As I said before, we are just getting started, and we are very excited going into Q1 and 2020 with this great momentum. We'll have an amazing year. Thank you.
This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
