In their words: Coach is the AI sales coach for in-person sales teams. Reps record every meeting, and the AI figures out what the 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 five times more reps. And every meeting feeds one sales brain, so leadership finally gets answers to the questions that used to be guesswork. The results so far: +32% average lift in conversion rate.
