Similarweb lifts 2026 outlook as founder Or Offer plans mid-2027 exit
Founder and CEO Or Offer will step down by mid-2027, while the company raises full-year revenue guidance to $307 million–$315 million and pivots reporting metrics toward enterprise clients.
Similarweb Ltd has reported its first-quarter 2026 financial results, highlighting increased sales productivity and resilience in its business model. The company raised its full-year 2026 revenue guidance to between $307 million and $315 million, reflecting management’s confidence in a second-half acceleration. Concurrently, Founder and CEO Or Offer announced his intention to step down by mid-2027, triggering an external search for his successor.
The firm attributed its Q1 performance to tangible returns on 2025 investments in its sales force and product portfolio. Sales productivity has increased for the third consecutive quarter, contributing to the strongest Q1 increase in Annual Recurring Revenue (ARR) since 2022. Net Revenue Retention (NRR) has stabilised at 98% overall and 103% for large customers, while gross retention reached a new two-year peak.
Strategic priorities are shifting towards the AI ecosystem, with data being licensed directly to Large Language Model (LLM) companies for pre- and post-training. The company successfully closed one large LLM contract that had been delayed from the fourth quarter of 2025, with two additional major deals still in the pipeline. New product launches, including Retail Intelligence and Ad Intelligence, aim to capture market share in fragmented e-commerce and paid media channels.
Similarweb is also pivoting its reporting metrics to focus on customers generating over $25,000 in ARR, which accounts for 86% of total ARR. This shift is designed to better reflect the company’s identity as an enterprise-focused organisation. Multi-year contracts now represent 64% of total ARR, up from 52% in the prior year, a metric management views as a key indicator of revenue durability.
Operational diversification continues with the expansion of the R&D centre in Prague to mitigate currency headwinds from the Israeli shekel. For the second quarter of 2026, the company assumes 6% year-over-year growth, acknowledging a difficult comparison against the prior year which benefited from a one-time revenue pull-forward. Or Offer will remain active as CEO through the transition period to ensure no disruption to current strategy.
