I built an AI coach so solo founders can practice sales calls before burning real leads (€19.99/mo, FR-first)

Hey IH 👋

Solo founder here. I built ClosR because I burned my first 5 sales leads in a week — panic on the price objection, monologuing, never asking for the close. Each lead cost me €50 in ads. Painful.

The market’s “solution”: €3,000 closing courses that are 90% theory. Or burn more leads.

What ClosR does: an AI coach that simulates realistic sales calls. The AI plays a prospect — hesitates, interrupts, throws objections like “it’s too expensive” or “I’ll think about it.”

You speak out loud. You panic at first. After 30 simulations, the words come out automatically.

After each call you get detailed feedback by phase (qualification, presentation, objection handling, close) and by skill (active listening, asking for the sale, silence handling).

Stack:

• Frontend: Vite/React on Vercel

• Backend: Node.js on Render

• Voice: OpenAI Realtime API

• Auth + DB: Supabase

Pricing: Free first simulation, then €19.99/month. No commitment.

Where I’m at: ~5 paying users so far, building distribution via TikTok organic. Just launched the website with proper SEO/GEO foundation this week (17 pages, llms.txt, structured data).

Why French market first: Best simulators (Hyperbound, Second Nature) are English and €50–200/month for teams. Nothing for solo French entrepreneurs at small price points.

Happy to answer anything. What would make you try it (or NOT try it)?
