Technographic intelligence — find companies by the technologies they use, with API and bulk export.
BuiltWith identifies the technologies installed on any website — analytics, ads, CRM, payment, hosting, frameworks, the full stack. The platform is the standard reference for technographic prospecting: "show me everyone using Shopify Plus + Klaviyo + Recharge" or "show me everyone who churned off Mailchimp." Used heavily for competitive displacement and tech-stack-driven outbound.
