About Radar

AI prospecting tool that finds, ranks and contacts local businesses in France

Radar is an AI prospecting platform for marketing agencies and freelancers who sell to local businesses in France. What it does Find: a national database of French local businesses built from OpenStreetMap, Overture Maps and the SIRENE registry. Users search by trade and area, or browse a map. No overlap: each business is assigned to one user only (reserved 21 days, 45 after first contact), so no two users chase the same lead. Prospect: AI-written briefs and outreach emails (Claude), sent from the user’s own domain with gradual volume ramp-up. Call: AI voice calls through Vapi, with a scheduled autopilot, inbound callbacks and live transfer to the user during their availability. Book: built-in calendar, meeting confirmation with .ics, iCal sync, and an AI prep sheet sent before each meeting. Convert: a shareable mini-audit page per business with verified findings, three priorities, the agency’s offer and a booking slot. Improve: a weekly AI coach report, per-user stats, and an admin dashboard for the whole group. Compliance and security Shared do-not-call list (HMAC hashes) applied across all users. Per-user data isolation with Postgres row-level security. No Google data stored (Places API removed for terms-of-service reasons). Stack: Next.js, Supabase (Postgres, Auth, pgcron), Vercel, Claude API, Vapi, Leaflet. Test suite with Vitest. Business model: users bring their own Claude and Vapi keys, so running costs stay limited to hosting. Currently offered free to students of a French marketing training program; no revenue yet. Status: live in production since September 2026. The voice-call autopilot is built and deployed but has not yet been validated on real calls.

What's included

All related design work, Source code, All related data

The national business database (about 590,000 records) and the import scripts to rebuild or refresh it. It comes from open data, so the buyer must keep the licence obligations: ODbL attribution for OpenStreetMap, plus the Overture Maps and SIRENE licence terms. Full documentation (README, NOTES, AGENTS.md) and the database migrations. User accounts and personal data are not included (GDPR). The buyer starts with an empty user base. The current branding (“Building Society”) is not included; the product is delivered under the Radar name and logo.

Reason for selling

I build several products in parallel and want to focus on the ones that already generate revenue. Radar is technically complete but needs someone with the time to take it to market.
