Thank you, Billy, and welcome to everyone joining us today. Let me start off by saying that I'm extremely pleased with our results for both the fourth quarter and full year. 2021 represented the strongest year of growth and profitability in the company history. During the fourth quarter and full year, we continue to validate our strategy of being an end-to-end tech and business platform with a focus on CTV, video and data, and continue to experience strong market adoption of our products. We remain encouraged by the results we are generating. We believe that our strong balance sheet, profitability and cash flow will enable us to maintain continued growth both organically and through potential M&A, while adding value for our shareholder through the $75 million share buyback we announced today.
I will begin by giving an overview of our results and strategy, followed by our Chief Financial Officer, Sagi Niri, who will review the highlights of our Q4 and full year 2021 financials. We will then open the call up for questions. For the three months ended December 31, 2021, we generated contribution ex-TAC of $88.6 million compared to $74 million in Q4 2020, representing 20% organic growth and adjusted EBITDA of $54 million compared to $39.1 million in Q4, which reflect 1.4x growth. These results were highlighted by continued growth in advertising spend on CTV, which increased 47% during Q4 2021 compared to Q4 2020, and greater adoption of our self-service and various tech-enabled programmatic offering.
The greater adoption of this technology solution supported our ability to generate strong profitability. The efficiency of our platform, our end-to-end strategy and the growth we achieved in this segment drove a 53% Adjusted EBITDA margin in Q4 2021 on a reported revenue basis and a 61% margin on a net revenue basis. We believe this margin represent the best in class for our industry. For the 12 months ended December 31, 2021, we generated contribution ex-TAC of $302 million compared to $184.3 million during the full year 2020, reflecting organic growth of 64% and Adjusted EBITDA of $161.2 million compared to $60.5 million during the same period last year, reflecting 2.7x growth.
These record results reflected the best year in Tremor history and serve as an indicator that customers prefer our offering, which provides simplicity and enhanced data through our differentiated end-to-end technology and business platform. Full year growth for Tremor in 2021 was also driven by increased CTV spend across our platform, which increased 108% compared to 2020. While we also continue to see the necessity of our managed service offering, we are currently seeing and expect to continue observing core growth driven primarily by our self-service solutions and programmatic offering. We believe the key to our continued growth and success in our differentiated end-to-end technology and business platform, which is comprised of a demand-side platform, data management platform, supply-side platform, and most recently, a CTV ad server.
Our strong focus on product development and every acquisition we have successfully integrated over the last few years has driven us towards creating the platform we have today, with the ability to service a wide variety of customers across all screens. We believe end-to-end is the most efficient model in the industry as customers desire simplicity, better data to enhance their retention targeting efforts, and to move towards supply path optimization. Because we maintain relationship with both advertisers and publishers, we are able to connect with them directly in the most efficient way while providing better insulation against future privacy changes. Customers leveraging us for their end-to-end buying needs also enjoy strong pricing advantages because we consolidate all transaction fee within one ecosystem to maximize advertiser budget going to the publishers.
Our end-to-end model also helped enable us to generate strong 2021 customer net retention rate of 150.3%. We believe these strong retention rates offer evidence that our model is working well and fulfilling our customer holistic needs. Furthermore, we believe this model is better for Tremor and its shareholders, as it enable maximum revenue opportunities and profitability through the cost efficiencies we achieve from splitting costs across both sides of our platform while owning our global server infrastructure. CTV and video remain key growth driver for Tremor as we saw 27% and 80% of our contribution ex-TAC respectively generated in these segments as of the end of 2021, as revenues grew 118% and 69% respectively during the year.
According to eMarketer, U.S. advertising spend on CTV is projected to grow at approximately 24% CAGR through 2025, while U.S. ad spend on video and CTV combined is projected to grow at a roughly 17% CAGR through 2025. We believe our footprint in this fast-growing segment should result in strong continued growth for Tremor. We have also taken steps to enhance and differentiate our offering within CTV, as evidenced by the recent acquisition of Spearad, our exclusive global ACR data partnership with VIDAA, the launch of Programmatic TV Marketplace, and the launch of our content-level targeting solution. Tremor is also well-positioned for challenges within the industry due to its robust data footprint, end-to-end technology and business platform, and focus on CTV. Privacy changes has been a significant theme in our industry, particularly around IDFA changes and cookie depreciation.
In addition, last week, Google announced a multi-year initiative to build the Privacy Sandbox on Android, which will limit sharing of user data with third parties and operate without cross-app identifiers. Tremor is well-positioned to address all of these changes due to our end-to-end operating model, as our DSP and SSP share the same audience graph, which eliminates data loss when syncing platforms. Our exposure to cookies from a revenue standpoint is also relatively low, which allow Tremor and its customers to remain well-positioned for privacy changes compared to other industry peers with higher level of third-party cookie exposure. We are confident that this combination of factors ensure we remain able to meet our customers' needs.
Regarding challenges associated with supply chain constraints and inflation, we saw evidence of lower advertising spend during Q4 2021, which have continued to this point in Q1 2022 in certain sectors, such as automotive, due to a chip shortage. However, these issues have been offset by increased demand in other segments, such as CPG. Our highly diversified customer base across our end-to-end platform has helped offset any significant adverse impacts to our business. We achieved a lot during Q4 2021 that help us to strengthen our offering within CTV. In October 2021, we strengthened our CTV and data capability through a unique and meaningful partnership with VIDAA, a subsidiary of Hisense, which provide us exclusive global access to ACR data starting later this year.
The partnership is expected to accelerate our U.S. and international growth. We anticipate this growth will mainly start in the second half of 2022 in key markets such as Canada, Australia, the U.K. and Germany. This powerful data partnership, which we will utilize for targeting purposes, provides access to VIDAA's distribution. We believe VIDAA currently reaches approximately 20 million smart TVs worldwide, and we expect this reach to grow to more than 40 million TVs in the coming years. VIDAA is the operating system for major OEMs that include Hisense, Toshiba and others. This partnership makes Tremor the only end-to-end technology platform with this type of exclusive data outside of the walled gardens. VIDAA has also proven that its relationship with Tremor extends deeper than data.
In January, VIDAA selected Unruly as its strategic SSP to enable global access to all its video and native display media, while also integrating our newly acquired CTV ad server, Spearad, to enable better control over the CTV ad delivery with granular ad pod control and targeting. In October 2021, we acquired Spearad, which provides Tremor with a global CTV ad server and header bidder featuring a robust user interface with advanced tools for ad pod monetization. We anticipate that the addition of the Spearad technology will allow us to capture a large segment of global CTV inventory through both current and future media partners, while providing added benefits to help those partners better control their inventory and maximize revenue opportunities.
Like the VIDAA partnership, we anticipate the addition of Spearad will open greater opportunities internationally, and we have already seen adoption of the technology by partners such as VIDAA. We forecast that the main contribution from this acquisition will start during the second half of 2022. In October, we increased our investment in CTV by announcing the launch of our Programmatic TV Marketplace, which is centralized platform for planning TV campaigns. The launch enabled advertisers to gain access to a diversified marketplace that feature premium TV-centric supply and curated PMP packages. Advertisers also gained the ability to leverage an efficient planning process to help improve and streamline cost, inventory, and reach, while gaining greater transparency into what inventory is included in each package. In December, we introduced in our SSP, Unruly, a content-level targeting solution which provides a new contextual solution for buyers amidst growing privacy regulations.
Content-level targeting allows buyers to tap into traditional linear TV buying tactics with granular targeting options like genre, rating, and show title within digital CTV and over-the-top environments. We believe this solution successfully positions Tremor and its customers for future changes in privacy. 2021 was an amazing year for Tremor from a business win perspective, and I will go over the major wins and highlights from both the fourth quarter and full year. As we mentioned, in the fourth quarter, we significantly enhanced our offering and innovation within CTV through our partnership with VIDAA, the acquisition of Spearad, and the launches of Programmatic TV Marketplace and content-level targeting. Our SSP, Unruly, significantly increased its reach and added 42 new U.S. supply partners during Q4 2021 across critical growth verticals in sports, entertainment and lifestyle, as well as OEM and Multicast Video On-Demand businesses.
This comes after Unruly added 35 new U.S. supply partners during Q3 2021. Our Unruly controlled offering has received amazing feedback from premium partners in the CTV arena. During Q4 2021, PMP revenue from this self-service platform for publishers saw an increase of 184% compared to Q3 2021. Tr.ly, our in-house creative studio, was heavily involved in many deals we promoted with customers and empowered campaigns while enhancing engagement in a meaningful manner. During 2021, creative requests through Tr.ly increased 74%. Tr.ly generated about 21,000 unique video creative and created CTV relationships and spending trends with our customers. Tr.ly is a differentiator for us as not many DSPs or SSPs have a creative studio in-house. This power house drives higher levels of campaign spend to our platform.
For example, new and existing clients who hadn't yet booked a campaign in 2021 spent an average of 301% more on their first campaign when leveraged Tr.ly creative solution. Our data-driven creative studio has experienced strong and growing adoption and combines two of our greatest advantages, our robust data footprint and our ability to provide all-screen creative solution to better support our advertisers' needs in connecting with consumers. Last year, we also recognized that large video advertisers were looking for complementary omni-channel solution to their video campaign, which drove us to launch the ability to run display and audio campaigns in our DSP. Additionally, we launched our TV Intelligence solution, enabling in-house TV retargeting and measurement solution that provide advertisers the ability to reach and engage TV viewing audiences at scale with data-driven video creative.
This solution received a further boost with our video data partnership, the launch of Programmatic TV Marketplace, and the launch of our content-level targeting solution, which also enhanced targeting capabilities for customers. Finally, we successfully executed a dual listing on the Nasdaq in June. We generated $134.6 million in cash proceeds, net of issuance costs, and enabled strong exposure to U.S. markets, greater access to capital, and increased access to broader investor base. Today, we are also very pleased to announce a $75 million share buyback program, which allow us to retain significant value to shareholders and take advantage of the opportunity amidst macro pressure that many companies within AdTech have been under recently.
We increased our cash balance by $270.3 million to $367.7 million as of the end of 2021. Our strong balance sheet and cash generating business enable us to implement this buyback, while we also continue to evaluate opportunities to acquire companies and continue to invest in technology, sales, and marketing. Finally, since our last earnings call, we have delivered on our promise to engage more proactively with the U.S. and international investment community. In November, we presented a Q3 update for U.K. investors and participated in RBC Global Technology Conference. In December, we participated in Raymond James Technology Investors Conference, and in January, we participated in Needham Annual Growth Conference. We also conducted a significant number of institutional investors meetings and participate in NDRs with numerous banking and IR partners.
Finally, we recently launched our inaugural quarterly IR newsletter, which we intend to update each quarter to make investors more aware of main developments at Tremor. Please subscribe on the investor relations tab on our website. It is now my pleasure to turn the call over to Sagi to review our financial results.
Thank you, Ofer. We were excited to see another record quarter of revenue, profitability, and strong business momentum closing out a fantastic 2021 and moving into the first quarter of 2022. Today, I will review highlights of our Q4 and full year 2021 performance, as well as some of the key financial and operational drivers for the quarter and year. Tremor International achieved an outstanding record quarter in Q4, with revenue and Adjusted EBITDA propelled by continued organic revenue growth. Q4 2021 net revenue increased 20% to $88.6 million, compared to $74 million in Q4 2020, all of which was driven through strong organic growth. This growth was particularly impressive when considering the higher levels of political spend from the U.S. election cycle across AdTech during Q4 2020.
CTV spend on our platform grew 47% in Q4 2021 versus Q4 2020, and we are well-positioned to continue this growth as more business is increasingly being transacted through programmatic platforms. We also continue to generate very strong Adjusted EBITDA and margins while investing in the critical areas of our business that can drive future growth. For Q4 2021, we generated Adjusted EBITDA of $54 million, which reflected 38% growth from Q4 2020, and Adjusted EBITDA margins of 53% out of reported revenue and 61% out of net revenue. For the 12 months ended December 31, 2021, net revenue increased an impressive 64% to $302 million, compared to $184.3 million in the full year 2020 period, all of which was driven through strong organic growth.
We focused on being highly competitive in the CTV and video space. As a result of the enhancements we made to our offering during the pandemic, CTV spend on our platform grew 108% in 2021 versus 2020, while our video net revenues grew 69% from $143.4 million during 2020 to $242.6 million during 2021. We continue to generate very strong adjusted EBITDA while investing in the critical areas of our business that can drive our future growth.
Costs were lower than expected, driven by a postponement of our return to office, lower marketing spend, and reduced travel and entertainment costs. During 2021, we generated full year Adjusted EBITDA of $161.2 million, which reflected 166% growth from 2020, and finished the full year with Adjusted EBITDA margin of 53% as a percentage of contribution ex-TAC. The significant growth and profitability we achieved during 2021 was driven by our data-driven end-to-end technology and business platform with a focus on the key growth segments in the market, CTV, video, and data usage. Our growth exceeded market expectation and proved once again that our strategy is working and our product and services adoption is accelerating. We believe we have a competitive advantage with our end-to-end platform versus point solution.
We have developed a highly profitable business model with high efficiency around operating costs, leading to operating leverage and economies of scale. Tremor is able to achieve significant profitability due to our ability to split costs across both sides of our end-to-end platform while maximizing revenue opportunities. We also achieve cost efficiencies as we own and operate our global server infrastructure, which results in significantly lower costs than we were to operate exclusively on third-party cloud services. As we mentioned previously, we believe we have best-in-class industry margin in operational profitability, and we for Q4 and full year 2021 generated Adjusted EBITDA margin of 61% and 53% out of net revenues, respectively.
Turning to our cash flow, we generated net cash from operating activities of $48.7 million for Q4 2021 versus $23.5 million in Q4 2020, an increase of 107%. For the twelve months ended December 31, 2021, we generated net cash from operating activities of $170.1 million versus $35.2 million in the twelve months ended December 31, 2020, which represent a 384% increase. As of December 31, we have $367.7 million cash and cash equivalent with no debt. We also experienced 98% free cash flow conversion during the quarter and for the full year 2021.
Non-IFRS diluted earnings per ordinary share is $0.27 for Q4 2021 versus $0.20 in Q4 2020, an increase of 35%. Eighty-three cents for the twelve months ended December 31, 2021 versus $0.28 for the twelve months ended December 31, 2020, which represents a 201% increase. As we look ahead, in order to continue achieving strong organic growth in the business and monetize our new partnership and acquisition, we intend to increase our investment in product and R&D as well as sales and marketing.
Finally, I now turn to our outlook. As a reminder, we expect that return to office, marketing and travel costs will add approximately an incremental $1 million per quarter in operating expenses this year. For the first quarter of 2022, we expect net revenue to be at least $73 million, and Q1 2022 adjusted EBITDA to be at least $33 million. This guidance underscores that our efficient end-to-end model focused on CTV is helping us achieve excellent growth and profitability. We believe that our growth profile and efficient end-to-end model, which enables strong profitability, investments for growth, and a healthy balance sheet, position Tremor to continue taking advantage of a rapidly growing digital advertising and CTV market, both in the U.S. and internationally. With my remarks completed, I'll turn the call back to Ofer.
Thank you, Sagi. To summarize, Tremor had a very strong finish to 2021 in what was a transformational year for the business as we achieved strong organic growth without contribution from acquisitions. We believe our data-driven end-to-end technology and business platform focused on CTV and video reflects the preferred model that our customers desire through the simplicity, insulation from privacy changes, supportiveness of industry trends, and ability to maximize returns. The 64% contribution ex-TAC growth and customer adoption we achieved during 2021, and the fact that we are seeing others in the industry attempt to replicate this structure only enhance our confidence that the model is working. This model also benefits shareholders as it enables significant profitability and cash generation, which allow us to expand our investment in technology, sales and marketing to grow the business organically while evaluating future M&A opportunities.
We also look forward to returning value to shareholders through a $75 million buyback we just announced. Tremor also continued to fulfill its promise to enhance and expand its CTV data and video capabilities, which now accounts for 80% of our net revenues and 91% of our programmatic net revenues. Our exclusive global ACR data partnership with VIDAA will enable targeting within highly desirable data sets and accelerate our international growth around CTV as we look to monetize the unique and meaningful partnership in the second half of 2022. We are also extremely pleased to have VIDAA select Unruly as a strategic SSP and integrate Spearad, which positions Tremor well for future U.S. and international growth with an aggressively growing partner for years to come.
Our recently acquired CTV ad server and header bidder Spearad allow us to capture a greater portion of CTV inventory globally with current and future media partners. The launch of Programmatic TV Marketplace and content-level targeting furthers our innovation and differentiation within CTV, while providing better insulation against privacy changes. Finally, we look forward to continue to engage with both U.S. and international investors through continued participation in conferences, tech demos, and NDRs with firms that cover Tremor. We believe we have a compelling value proposition for investors and remain excited for additional future opportunities to tell our story. Operator, we will now open the call to investors' questions.
We will get to our questions and answers in just one moment. Our first question is from Matt Swanson of RBC Capital.
All right, thank you guys so much for taking my questions and congratulations on a strong finish in, you know, what's been kind of a challenging environment here. You know, Ofer, I think you did a great job of explaining kind of the lack of risk from some of the signal loss, but kind of flipping that. You know, based on all the new offerings you have, whether it be the Programmatic TV Marketplace, content-level targeting, the creative suite, and obviously both your, you know, data sets coming from VIDAA and then the data you get from a full stack, what do you think the potential is for signal loss to actually be a catalyst for the company and to be something that, you know, becomes more about market share gains than risk, especially kind of in the wake of SPO?
Hi, Matthew. It's a great question and a great point to discuss. I think that what we understand, what we see now in the marketplace is that everybody is preparing, of course, for this loss of signals in the market. I think that Tremor in general is better suited to deal with it because of our basically heavy reliance on CTV and growing on CTV and mobile and less on cookie-supported businesses. That's one. The second thing is the end-to-end solution that we spoke about and the data that we are able to gather from partnerships that we do. I think that this can become like a potential advantage in the future. I hope that all the other companies and all our peers are of course preparing themselves also for this situation.
I think as we mentioned also in the notice, that we are well situated in this situation in order to tackle it in the coming years when all this regulation and changes in security will come into effect. I think that when people are now viewing and looking for partners for long term, they can rely basically on Tremor to be that partner for the long run.
Yeah. No, no, absolutely. Sagi, kind of thinking through guidance, it was helpful to get the context around the supply chain and the inflation concerns in Q1. We also have VIDAA coming on in the second half as well as, you know, expectations for a return of a lot of political spend. Can you give some context on how that might kind of work out in terms of full year seasonality? Does this feel like maybe more of a back half loaded year?
Yes. Hey, Matthew. Thanks for the question. I think, again, as we said previously, we don't have like real concentration on any vertical. Supply chain issues of course affecting, you know, the macro globally. I think that we are well-positioned in order to increase some other verticals that are not affected from that issue. We did it in the past and during 2021 and probably we'll do it in 2022. Regarding VIDAA, I think, again, as Ofer mentioned, it kicks in in the first of May. It will give us a lot of exclusive ACR data which we can execute for the first time outside of the U.S. internationally. We are very excited in doing that and take our international activity much further and scale it up in 2022.
Again, we are waiting for that as well as our clients and publishers and partners and it will happen.
One more thing to add to Sagi is Spearad that we acquired in last October that is in the first quarter now is being integrated into Unruly. We believe that it will make its major effect starting from the second half of this year, because as we know, these cycles of integrating ad servers and header bidders are taking longer time than usual business. We believe that it will start affecting the business more key in the second half of the year going forward.
All right. Thank you guys.
Our next question from Laura Martin of Needham.
Hi there. Great numbers, you guys. You should be really proud of these. Congratulations. I have a couple. Thirty-eight percent of your net revenue came from third party DSPs, is my recollection, and I'm really interested in The Trade Desk announced OpenPath and whether that has a positive or negative impact on Tremor as the largest DSP tries to squeeze out some of the supply path optimization. Can you comment on that?
For sure. Thank you, Laura and I. I think that The Trade Desk move will create a few things in the marketplace from what I understood until now. One of them is that publishers basically will have to. Sorry, I will rephrase it. I will rephrase my answer. I think that when you look at that, publishers already got more than one way to connect to a bidder to sell their traffic. They will make the effort and open more channels to work with an SSP if they have an advantage of doing that.
Unruly and Tremor, in this case, got a lot of inputs to bring and a lot of value to bring to publishers, like additional data, unique and exclusive demand that we bring from our DSP when we sell it and from self-serve and from PMPs and so on. I believe that in this case, when publishers that are working with us and they will switch to other platform and other systems in order to connect to us in order to get our demand from The Trade Desk, and I think that we have no issue with that because we really bring value. In cases that an SSP doesn't bring value to these publishers, I think that the publishers will not connect to this SSP anymore.
Basically, I think that this move of The Trade Desk is basically reinforcing and accelerating of the supply path optimization. As a company that so much advantages to work with working with publishers, that we deliver them so much advantages, I don't think that we have any issues connecting them, and we already know that we can connect through Prebid and other means in order to run campaigns on them, even through The Trade Desk for The Trade Desk. For us, it's a no issue, or even in some cases, because the number of SSPs that will work with The Trade Desk will lower, it will give us some advantage.
Yeah. I think just to add to Unruly, we are very happy from the announcement of The Trade Desk because it's validating our end-to-end solution. We are happy that others seeing the advantages in that as well.
Yeah.
Super helpful, really. Thank you. Then my second and then my last question will be about. I'm really excited about the bottom-of-funnel advertising opportunities for CTV, and so that naturally takes you to the e-commerce convergence with CTV. I'm interested in your thoughts there. One of your competitors said that not to have an e-commerce strategy in 2022 is like not having a mobile strategy 10 years ago. Okay, that's hyperbole. My question is, when you think about CTV over the next year or two, do you agree with him that e-commerce and bottom-of-funnel is gonna be a big growth driver for CTV ad revenue?
Thank you, Laura, for that. I just want to remind you that in our previous conversation, we spoke about it, and I mentioned that I think that the big volumes of CTV media will be fulfilled also by performance-related campaigns. Which by doing that, we mean, of course, lower funnel and e-commerce is a very big part of that, but there are also, you can sell products or services through performance. So for sure, we do that. It's we sure think that this will be a very major player. I agree with the statement that you just said that if you are not building a lower funnel or an e-commerce strategy around CTV, probably you are missing something very big.
We agree to that, and we believe that CTV will open also to performance advertising and performance video because it's happened in other verticals, if you remember, that we spoke about in the past, and I think that it will happen also in CTV. We know that, and we are getting ready for that. This is something that is on our plate for a long time.
That's super helpful. Thank you, guys, and great numbers. Congratulations.
Thank you.
Thank you.
Thank you.
Our next question from Mark Kelly, Stifel.
Hey, great. Thank you very much. I appreciate you taking my questions. I had two quick ones. First one is on the increase in R&D for this year. I guess, is there a component of that that's kinda one-time in nature to get ready for this upcoming VIDAA partnership? That's the first one. The second one is, can you remind us what political was in Q4 of last year, just to give us a better sense of, you know, the growth ex political? Thank you.
I will start by saying that we are putting a lot of emphasis in the last two years on technology and innovation, mainly in CTV. You can see also when we spoke about all the things that we've done in the past year, and we spoke about TV marketplace, and we spoke about content-based targeting, and we are talking about, of course, Spearad and the integration of Spearad into our technology and tech stack, full integration, basically, not just connection. When we are talking about the VIDAA of course to build it and to integrate it into our ecosystem. All of that, of course, is innovation and things that enhance our capabilities around CTV.
We are proud of that, and I think that in this ecosystem that we are living now, we need to invest in technology and innovation around CTV because this is a major part of our future and a very big revenue source already of today's revenues for us. It's 25% already of our business. I think that we will keep innovating and building tools around CTV, and Sagi can talk about one-time and about the political now.
Yeah. Again, to add to what Ofer said, I don't think it's a one-time like increase in R&D and product, which we are doing, you know, all the time, and we are doing it also in marketing and sales. It's an increased investment in those fields, as Ofer said, because we are a technology company, and we need more and more components in order to scale our business up. By the way, it's not related to VIDAA. We've done it before, and probably we'll do it more in the future. VIDAA as well is investing a lot, you know, on their side, to develop some tools in order to help them and us to facilitate their ACR data and their inventory.
Regarding political spend, I don't have the exact number or the absolute number we did in Q4 and a little bit in Q3 2020. It wasn't like very material, but we did to some extent a couple of millions of dollars on that as well.
Okay. Very helpful. Thank you both. I appreciate it.
Thank you.
Our next question from Andrew Boone of JMP Securities.
Hi. Good morning, and thanks for taking my questions. Two, please. The deck talks about a 74% increase in creative requests in 2021. Can you talk about the drivers just behind the greater use of creative? And then just I know you mentioned the competitive differentiation in your prepared remarks, but can you just talk a little bit more about that of whether that's truly an on-ramp for new customers, whether it just drives more spend? Like, how should we think about that?
About the creative requests. Yes. I think that the pandemic, in general, created a situation that creative is getting much more stage in this business because people want to control better the how they engage with their customers because there is a lot of sensitivity and a lot of things that happened, not just the pandemic, but also in the world in the last two years, a lot of social unrest that was related to you know, in the U.S. and in other places as we see today. People want to control the way they engage with their clients and potential customers.
I think that what happened in the last two years is something that is like transformational in many ways because advertisers and clients are looking to get, like, better creative response and better options in order to run their campaigns. I feel that I was asked in the past, and I think that when I'm thinking about it again and again, I think that this is something that will stay for this pandemic, meaning that people will like to control more of their messaging. Targeting is part of that, and we're already doing a lot around data, and we are signing a lot of unique and exclusive data partnership in order to enhance this targeting capability. But on top of that, you can see a lot of importance now around the messaging and in order to create more efficient creative.
We saw a very big trend in the last two years, but mostly in 2021, that people are using this solution that we provide. We are unique in that because we don't know a lot about a lot of other SSPs or DSPs that are using or providing these capabilities to their clients. We are doing that as part of the package when we are offering to the clients and the customers to run with us.
That makes a lot of sense. That's my second question. I wanted to touch on the contextual tools that you're talking about. Are you seeing more demand for this for advertisers as there are greater privacy announcements? Like, where are we in terms of the adoption curve for contextual tools more broadly across digital advertising? Thanks so much.
Thank you. Yes. We saw that when we announced this solution, we got a lot of people that approached us, asked for more information and to get to know more about the product because they want to test it and use it. I think that it shows that people are taking into account that there will be changes around privacy, and they need to adapt and to learn about more tools that are capable of using in order to run basically in the marketplace also after these changes will occur.
We already engaged with a lot of clients and customers around it, and I think that it will just enhance because we just saw now Google also added this, sandbox issue with Android, which is of course creating more, let's say, requests from people to find solutions for targeting and so on and so. I feel that it's the right solution in the right time. Together with the other advantages that we got, and we spoke with Matt before about end-to-end solution and the fact that we are mostly running on CTV and mobile, and we are using, you know, audience graphs, which are
Shared by the DSP and SSP and so on. We are providing them like peace of mind that we are here to stay, and we can provide them solutions also in the future.
Thank you so much.
Our next question from Andrew Marok of Raymond James.
Thanks for taking my question. You've talked in the past about your focus on programmatic revenue versus non-programmatic. Over the last couple quarters, we've seen the non-programmatic accelerate while programmatic came in at about 11% this quarter. What are some of the moving pieces that went into the dynamic in 4Q, and how should we be thinking about the growth in the respective lines into 2022? Thanks.
Again, I think as we said in the past, you know, performance is where we grew, and it's our. We are proud of that. Having said that, we are not investing a lot in that activity. It's like a activity that we did a lot in the past, and it's a. We are calling it like a legacy. Again, we are not aiming to grow this part of the business, but we are not angry if it's happening. In 2021, what happened, we estimated that this activity will decrease by 30%, but it increased instead. Going into 2022, I think that the aim is, you know, to keep this activity on a flat basis. This is what we are aiming.
By the way, the beginning we wanted to estimate it as a decrease, but we saw the number, we saw the trend, so we are keeping it flat.
Understood. Thank you.
This concludes our question and answer session. We now turn the call back to Ofer Druker for closing comments.
Thank you. Thank you, everyone. I think as I said, we had a very exciting year last year, and we finished it very strongly. Thank you for your support and your interest and for the questions. I hope to see you soon in our additional calls that we'll have during the year. Thank you very much.
Thank you, ladies and gentlemen. This concludes today's conference. Thank you for participating. You may now disconnect.
