Welcome back to AI for Founders, I'm Ryan Estes.

What happens when your most reliable teammate isn’t an app… it’s a voice that calls you at exactly the right moment? Today we’re meeting the founders of Commitify, an AI accountability coach with personalities—Life Coach, Zen Master, Slay Bestie, Hype Beast, Drill Sergeant, and CEO—that literally ring your phone to snap you back into flow. The tension: real friends have boundaries and bias, therapists have calendars and copays, and apps are drowned in notifications. Commitify bets the future is UI-less voice with long-term memory that feels like a friend and works like a coach.
In this episode, you’ll learn why they chose phone calls over screens, how they design agent personas that motivate without being cringey, what “memory” should and shouldn’t remember, the wild origin story (a 100-hour hackathon sprint), pricing by calls per week, and how they’re hunting for a true ICP before scaling. This one’s for founders, builders, and product people who want big retention with small surfaces—and anyone exploring AI that actually changes behavior, not just creates content. Let’s get into it.
