For sales and marketing teams prospecting by tech stack, BuiltWith is a website-technology profiler that identifies which tools, frameworks, and analytics platforms any site runs, then turns that into lead lists of companies using specific technologies.

BuiltWith occupies the technographic data layer of GTM, turning a company’s web stack into a prospecting and account-research signal. Its presence is steady in operator workflows built around identifying which technologies target accounts use, then combining those findings with firmographic, hiring, funding, and other public signals. It appears in discussions of tech-stack displacement, tighter outbound targeting, account scoring, and enrichment workflows run through coding agents or GTM orchestration tools. The company’s VAT API extends that domain-to-company-data workflow beyond its established technology profiling product.

Business Profile
BuiltWith started in 2007 as a side project built by Gary Brewer to identify the technology behind any website, run in spare evenings before Andrew Rogers joined as co-founder a few years later. The company has stayed self-funded and deliberately small, based in Sydney and run today by a team of four, reporting $31 million in revenue for 2026. That combination, a lean team supporting a widely used prospecting and technographic-data product, has become part of BuiltWith's own story, cited often as an example of how far a bootstrapped, tightly run software business can scale.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
BuiltWith makes its technology-detection data available through an API, MCP, SDKs, and a CLI, giving agents and developer workflows multiple ways to run technographic lookups and build prospect lists. Its recent product messaging also includes a VAT API that converts domains into company registration data. The public surface is built around programmatic access to website-technology and company data rather than a separate agent application.
