COACH on the record
What they shipped
- From its YC profile: 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. (source)
- Its own site describes it as: "AI Coach gives every field sales rep personalized coaching after every meeting, helps managers prioritize coaching opportunities, and turns customer conversations into actionable sales intelligence." (source)
