BuiltWith is the original technographic intelligence platform, tracking the technology stacks of 673M+ websites globally. It's the foundational source for understanding what CMS, analytics, marketing tools, payment processors, and infrastructure any website runs — used by sales teams for targeting, by marketers for competitive research, and by developers for market analysis.
Product Overview
BuiltWith crawls and fingerprints websites continuously, detecting the presence of JavaScript libraries, pixels, frameworks, CDN providers, CMS platforms, email service providers, and thousands of other technology signals. This creates a real-time map of the global web's technology landscape. Sales teams use it to find companies running specific competitor software (for displacement) or complementary tools (for integration-led prospecting). It covers both current and historical technology usage, so you can see when a company switched from one tool to another.
RevOps Jobs-to-Be-Done
- Technology displacement targeting — Find all companies using a specific competitor platform and build outbound sequences offering migration or displacement. KPI: Build highly targeted displacement lists in minutes rather than weeks of manual research
- ICP refinement by tech stack — Validate your ICP by filtering prospects based on the tools they already use — target only companies using complementary or integration-partner software. KPI: Improve outbound conversion by targeting only stack-aligned accounts
- Market intelligence and sizing — Quantify the total addressable market for a specific technology category by seeing how many companies use tools in that space. KPI: Validate market assumptions with real adoption data
