The AI Coach for in person sales reps.

Coach is the AI sales coach for in-person sales teams. Reps record every meeting, and our AI figures out what your best closers do differently, then coaches everyone else to do the same, with precise, personalized feedback after every meeting. Managers finally see 100% of what happens in the field: Coach flags who's stuck and why, so they only step in when it matters, and can coach 5× more reps. And every meeting feeds one sales brain, so leadership finally gets answers to the questions that used to be guesswork. They finally see the game of their team not just the scoreboard. Our bet: in the AI era, in-person sales will only matter more. It may end up being one of the last truly human jobs. Our conviction: any motivated rep can become a great one, meeting after meeting. The results so far: +32% average lift in conversion rate. COΛCH, post-game video analysis for field sales reps. YC S26

COACH: The AI coach for in-person sales reps
See original launch post

Hey everyone, we're Mathieu, Thomas and Nicolas, two brothers and a best friend building COACH.

TL;DR: We're building the best coach for in-person sales ever built: reps record every in-person meeting from our app, and our AI turns it into precise, personalized coaching. And it works so well that 5 months in, thousands of reps already run on COACH, and we're live with the top 5 in-person sales companies in France, lifting conversion rates by 32% on average.

The Problem

85% of sales in the world happen face-to-face. And in-person selling is brutally hard: a rep alone in someone's living room, reading signals, handling doubts, feeling the exact moment to push.

The best reps catch what no playbook can teach. That's why 20% of them bring in 80% of the revenue, and nobody knows what they're doing differently. The only way to find out is to physically be there: a ride-along, a full day, 100 km of driving to watch a single meeting. It doesn't scale.

The Solution

COACH's AI learns how to close customers for your business, and closes the gap at every layer of the sales org:

  • Every rep gets a personal coach: they record every in-person meeting from our mobile app, in-home, showroom, door-to-door, and walk out of each one with personal, precise feedback and a clear path to the next close. Our AI learns from your top 20% and coaches everyone to perform like them, starting each day with a morning brief on their weakest point. 90% improve on it in their first week.
  • The company gets a sales brain that learns how to close its customers: every meeting feeds it. Why is one region closing twice as much as another? Which objection is killing deals this month? Leadership just asks, COACH has the answer.

Thousands of reps already run on COACH, live with the top 5 in-person sales companies in France, where we've lifted conversion rates by 32% on average, and dozens of reps 3–4×'d their numbers. We're now growing fast in the USA, where our first customers are switching from virtual ride-along platforms to COACH.

Every rep gets a coach. Your company gets a brain.

The Team

At 18 and 21, we built Alsace Test: a 44-rep field sales team that did €3.5M in 14 months. Alsace made us fall in love with in-person sales, obsessed, actually.

And one thing was driving us crazy: same product, same material, same training, and one guy closed 4× more than the others. We were driving 2,000 km a week just to watch reps sell.

So we asked them to record themselves. Suddenly, without moving, we were listening to 10 hours of meetings a day. That was COACH before COACH.

In an AI-driven sales world, we're deeply convinced Zoom sales and call centers will soon be replaced by AI agents. Face-to-face selling will be the last human job on Earth. We're betting on it.

Our Ask

If you run 5+ field sales reps, let's talk, we'll show you how to make them superhuman.
