What SimilarTech does

SimilarTech is a B2B technology intelligence platform founded in 2014 in Tel Aviv, Israel, that tracks web technology adoption across more than 100 million websites, 20 million companies, and 4 million mobile applications. Acquired by Similarweb in April 2021, it now operates as a wholly-owned subsidiary brand within Similarweb's broader digital intelligence suite. Its core product set comprises five technology-intelligence tools — Competitor Technologies, Website Technologies Checker, Company Technologies Checker, Search Companies by Technology, and Contact List by Technologies — that allow sales and marketing teams to identify companies by their technology stacks, monitor competitor technology changes, and build prospect lists from technographic signals. The underlying asset is a proprietary web-crawling data engine that maintains 10 years of historical data, indexes 5 billion search terms, crawls 10 billion content pages, tracks 250 million display ads, and monitors 235 million product SKUs.

The platform is integrated with Similarweb Sales Intelligence, which extends the offering to territory planning, lead scoring, lead enrichment, prospecting, account-based marketing, buyer intent signals, and value selling. Two generative-AI agents — Meeting Prep and Sales Outreach — automate meeting brief generation and personalized outreach messaging using digital signals, account insights, and buyer intent data. Distribution is hybrid: a freemium suite of free tools (Website Traffic Checker, Company Profile Checker, Technology Checker, Top Websites) drives top-of-funnel engagement, a Chrome extension supports mid-funnel prospecting, and enterprise subscriptions convert users to paid plans. Named customers on the marketing site include Adidas, The Economist, AliExpress, Google, Booking, and Walmart. Revenue is generated through recurring SaaS subscriptions; specific pricing is not publicly disclosed but follows a freemium-to-enterprise upgrade path within Similarweb's broader go-to-market.
