Analyst · William Blair
Thank you, Rami, and welcome, everyone, joining the call today. Just before I start reviewing Q1 results, I want to address the announcement we made this morning. Today is a symbolic day for me. Today is exactly 5 years since our IPO and running Similarweb as a public CEO. This is also my 19th year of service since start working on Similarweb in June 2007. My promise to myself and to my wife was always that when I reach 20 years of service, I will realign my priorities and spend more time with my family. This moment is about to be reached as I enter my 20th year leading Similarweb next month. Similarweb has been my life work. I founded this company nearly 20 years ago. And as I approach that milestone, I believe this is the right moment to begin identifying the leader who will take the company forward. The Board and I are fully aligned on the timing and the process, and we have intentioned a search with a leading executive search firm. I will continue to serve as the CEO through the conclusion of the search and the transition period with my successor, with the leadership transition expected to be completed by mid-2027. I remain fully focused on the execution of our strategy for our shareholders, our customers and our employees. We came out with a great Q1 results and have a very strong confidence for this year's performance. There is no change in our strategy, our operation or our financial outlook. I'm proud of the business we have built and confident in what lies ahead. With that, let me turn to our first quarter 2026 results. I'm super proud of the performance of the whole Similarweb team during an eventful first quarter that included a month of conflict in the Middle East. Once again, we demonstrated our ability to deliver and the resilience of our business. Turning to the highlights of the first quarter. Revenue and operating profits came in the top end of the guidance range. We delivered 10 quarters of positive normalized free cash flow. Our NRR has stabilized, and we expected these metrics to improve in 2026, driven by execution of our customer expansion playbook. Gross retention trends in the quarter were excellent. The pipeline of the commercial opportunities is very strong, growing and providing confidence for the remaining of the year and beyond. AI-related revenues continue to expand and adoption of our AI solution is growing. First quarter performance provides a solid base for 2026, and we have decided to raise the lower end of our guidance for 2026 to reflect increased confidence. Turning to our results. Revenue grew 10% year-over-year to $73.9 million at the top end of our guidance range. We are starting to see tangible returns on the investments we made in the sales force and product portfolio in 2025. Sales productivity increased for the third quarter in a row, and this has contributed to the best Q1 increase in ARR since 2022. We reported non-GAAP operating profit at the top end of our guidance range. We generated $6.6 million in normalized free cash flow in the first quarter, reinforcing our commitment to profitable and durable growth. Net revenue retention for all customers was 98% and 103% for customers above $100,000. We are very encouraged that those metrics have stabilized in the first quarter and that gross retention continues to improve. We are focused on driving an improvement in NRR, specifically in the upsell motion in 2026 by executing our customer expansion playbook and leveraging our diverse product portfolio. Demand for our GenAI data and solution is truly amazing. Our AI revenues continue to expand, and we are engaging with more AI native companies as well as companies of all sizes that have realized that they need to understand what's happening in the new digital world. During the quarter, we signed one of the large LLM contracts that were pushed back from the fourth quarter of 2025. We continue to progress on the second and third deal as well as on multiple deals for our unique digital data and view of the digital world. We believe we are well positioned to be an AI winner with multiple commercial opportunities across data, product and distribution partners, and we are excited about the potential. Let me run through our AI data and product strategy, how we power the ecosystem, build AI-first solution and expand distribution at scale. First, we are powering LLM and AI agents. We are seeing strong traction in licensing our data directly to leading LLM companies for both pre- and post-training use case. At the same time, autonomous agents require trusted, structured digital intelligence to operate efficiently. That's exactly what we provide. Our data is built for both humans and agents, and we see accelerating demand for both. Second, we are building our own AI native solution. With GenAI Intelligence, we are helping brands to improve their GenAI visibility and sentiment. We are seeing strong market validation on this front, including recognition of our leadership by G2. We believe our data provides an important competitive advantage in this new market, and we are on a journey to become a market leader in this category as well. Last quarter, we launched Similarweb AI Studio and the response from the customers has been truly amazing. AI Studio is an AI-powered interface that allows users to ask business questions in plain language and multiple languages and instantly receive actionable insights. What used to take time and specialized skills can now happen quickly and easily across all of our data sets. AI Studio expands the number of users who can leverage Similarweb, increases engagement, enable faster and smoother insight generation and unlock a new consumption-based monetization model. We are seeing strong adoption and utilization across our customer base, AI Studio represents a huge shift in how users interact with Similarweb data. Third, we are expanding distribution at scale. Through partnership with leading LLM and agent platforms such as Manus and through MCP integration, we are embedding Similarweb directly into AI ecosystem. We want to meet our users where they are and increasingly, research and decision-making is happening inside the new AI platform. Last quarter, we shared that our MCP was available in Claude. And today, I'm super proud to share that we have launched MCP integration with ChatGPT. This integration is the same as our MCP Cloud Connector, providing seamless access to our data and tools. Claude and ChatGPT are 2 of the largest AI platform in the market. And today, hundreds of our customers can plug in Similarweb data directly into them, building automation, powering agents and asking complex question on the fly and receive insight, recommendation and action wherever they choose to work. Yesterday, we announced an expansion of our partnership with Manus, which we told you about last quarter. This partnership has been a big success, and we are glad to expand the data Manus user can access and also enable our customers to connect to Manus via an MCP to generate even more valuable seamlessly combining our data and Manus tools and capabilities. This ecosystem partnership unlocking new customers, expand our TAM and position our digital data as critical ingredients for AI-driven research and decision-making. Our AI pipeline is expanding rapidly with a healthy combination of large deals and continued expansion across our enterprise customers. We're excited about the potential this rich pipeline of opportunities provide. Our mission is to help companies win in the digital world, and we gain more market share. As part of this mission, we continue to develop and launch innovative products that empower our customers with the tools and capabilities of more than [indiscernible] 650 online stores and marketplaces. Retail Intelligence gives brands, sellers and retailers a unified view of shopper behavior, digital shelf performance, product mix, availability and pricing across fragmented e-commerce channels. It also adds keyword optimization, competitive benchmarking and digital shelf automation. As AI reshapes product discovery and retailers expand marketplace and retail media networks, Retail Intelligence help customers understand where demand is forming, how brands are winning and which action can improve sales performance so that they can win in a highly competitive e-commerce market. Also during March, we also launched Similarweb Ad Intelligence, leveraging the synergies with the Admetricks, which we acquired in 2024. Ad Intelligence delivers a unified view of paid media across search, social and display and soon LLM ads, revealing who investing, what's bringing more traffic and who gaining share across every channel and region and help brands understand paid marketing ROI. The solution addresses the most severe pain points advertising face today, knowing what competitors are spending and where, if ad spending is generating the decent return and helping advertisers identify where they are overspending, underspending or missing opportunities across channels. Until now, advertisers had to rely on fragmented data that leads to inefficient ad spend and wasted budget. With this product, we empower brands, agencies and publishers to work smarter, helping them to spot growth opportunities, benchmark performance and optimize spend across every channel and market. To summarize, during the first quarter, we have taken action to improve our performance. We are sharpening our go-to-market strategy, refining processes and building scalable playbook to drive cross-sell and expansion. We are seeing encouraging signs of improvement across the business, and this has increased our conviction in 2026. We believe that we are well positioned to capture long-term AI-driven opportunities. Our AI-first portfolio is scaling, ecosystem partnerships are expanding, and we are targeting high-growth segments like LLM companies, large big tech players and OEM with our own dedicated go-to-market.
