No tracking. No scoring. No idea which leads are hot or where they came from.
Point your form to our URL and get instant lead capture with automatic UTM tracking, device detection, IP geolocation, and AI-powered lead scoring.
Basic users: just a POST URL. Advanced users: drop in our SDK script for full telemetry. Both take under 2 minutes.
