The definitive technology graph for revenue teams.
Technology stack detection for every website—accurate profiles, verified contacts, and 20-year intelligence that powers precise targeting.
Our mission.
At TechnologyChecker.io, we believe every go-to-market team deserves accurate, actionable technographic intelligence. We built GTM stacks at B2B companies and kept hitting the same wall: knowing who to contact required knowing their technology stack—and doing that at scale was painful. Traditional solutions were either shallow, stale, or disconnected from contacts and workflows. We engineered a detection and enrichment platform purpose-built for revenue teams, combining crawler engineering expertise with GTM operations experience to deliver the web's most comprehensive technology graph.
