What BuiltWith does
BuiltWith, founded in 2007 and headquartered at One International Towers in Sydney, Australia (operating as BuiltWith® Pty Ltd), is a privately held website profiling and technology intelligence platform. Its core product crawls and fingerprints the technologies deployed on websites, tracking 113,002+ web technologies across 478 million+ domains with 41 years of historical data dating back to 1985. The platform is complemented by a portfolio of sub-products: Trends.BuiltWith.com (adoption analytics), eCommerce Product Lists, Keyword Lists, BuiltWith Ask™ (natural-language query), Top Sites rankings, Technology Investor and Public Companies analytics, downloadable Datasets, Browser Extensions, and CRM Integrations. The LeadsEye™ add-on pairs homepage screenshots with monthly technology spending metadata to support visual lead qualification.
The company monetizes primarily through tiered self-serve SaaS subscriptions starting at $295 per month, with annual billing options and a free tier for basic lookups that drives top-of-funnel acquisition. Distribution is global and product-led, supported by SEO, an affiliate program (whose data is cited by Statista and similar publishers), localized sites in 10 languages, and an API plus Model Context Protocol (MCP) server exposed through Composio for AI-agent access. The go-to-market targets B2B sales and go-to-market teams, sales-intelligence professionals, technology market researchers, and investors/financial analysts.
BuiltWith operates with approximately 11 employees and an estimated $22.6M in annual revenue, implying revenue per head of roughly $2M — an unusually capital-efficient profile enabled by its proprietary technology-detection pipeline and bootstrapped, 18-year operating history. The company has not raised institutional funding per the available record; co-founders Gary Brewer and Andrew Rogers lead the business.

BuiltWith competitors and assessment
Company assessmentBroad incumbents
- ZoomInfo: ZoomInfo is the largest B2B sales intelligence and technographic data provider, with a much broader contact/company database. After acquiring Datanyze (a BuiltWith direct competitor), ZoomInfo is the dominant incumbent offering comparable web technology data alongside contact data, sales engagement, and intent.
- Clearbit (HubSpot): Clearbit, now part of HubSpot, provides company-level intelligence and enrichment APIs including technology detection and firmographics. It overlaps with BuiltWith's API and enrichment use cases but is embedded inside HubSpot's broader CRM/marketing platform.
Direct peers
- Similarweb (SimilarTech): Similarweb acquired SimilarTech in 2018 to offer web technology detection and lead generation. SimilarTech directly overlaps BuiltWith's core product on website technology profiling, though with substantially smaller technology coverage (~8,000+ technologies vs. 113,000+).
- HG Insights: HG Insights provides technographic data and account intelligence for B2B sales and marketing teams, with deeper focus on enterprise technology spend analysis. It directly competes with BuiltWith's technology spend metadata and alternative financial data offerings.
- Apollo.io: Apollo.io offers a sales intelligence platform combining a large B2B contact database with company-level technology and intent data. It overlaps with BuiltWith in serving SMB and mid-market GTM teams with technographic and lead generation capabilities at a lower price point.
- 6sense: 6sense is an account-based orchestration platform that combines technographic, firmographic, and intent data. After acquiring Slintel (a BuiltWith-style technographic provider), 6sense directly competes in the same technographic + lead intelligence category.
- Demandbase: Demandbase provides account intelligence, technographic data, and ABM orchestration for enterprise B2B sales and marketing teams. It overlaps with BuiltWith on technology-based account identification and prioritization.
- Wappalyzer: Wappalyzer is a website technology profiler that identifies CMS, frameworks, analytics, and other tools on websites. It offers browser extensions and APIs comparable to BuiltWith's technology lookup and toolbar products, though smaller in scale.
- Datanyze: Datanyze was a direct technographic intelligence competitor to BuiltWith before being acquired by ZoomInfo in 2018. It remains a useful benchmark for BuiltWith's historical competitive positioning in the lead-generation-by-technology category.
- Slintel: Slintel provided technographic and buyer intent data for B2B sales teams before being acquired by 6sense. It was a category competitor with comparable technology-tracking capabilities focused on SaaS buying signals.
