Catalyst is a social accountability platform for people who are serious about their goals. No confetti. No badges for showing up. A system built on the one thing that actually changes behavior: consequences. HOW IT WORKS Set a goal that matters. Catalyst breaks it into daily tasks. Then you prove your execution every day with a Daily Reflection: what you did, what you didn't, and what happens tomorrow. Your reflections become your track record. THE CYCLE When you're ready to make it real, start a 30-day Cycle: - Commit a Participation Fee — from $50 to $500. It's non-refundable. - Submit a Daily Reflection every day for 30 days. You get two lives — miss two days and the Cycle fails. - Complete all 30 days and you earn every dollar back as a Completion Bonus. - Quit or fail, and the money is gone. The only way to see that money again is to earn it. That's the point. THE MASTERMIND Every Cycle places you in a mastermind group of up to 10 people at your commitment level, in it at the same time as you. They see your reflections. They notice when you go quiet. Accountability you can't mute. THE FEED No influencers. No motivational wallpaper. A feed of real people doing real work, one day at a time — and posting proof. WHO IT'S FOR People with money on the line behave differently. If you need a gentle nudge, this isn't your app. If you're done negotiating with yourself — welcome.
