Gauntlet

Gauntlet bets your friends money on Strava challenges and it actually works because nothing motivates you quite like knowing someone will Venmo you $50 in USDC if you skip your Tuesday run. John Morrow and his maker team figured out that the gap between wanting to be fit and actually being fit is pure financial fear, which is exactly the kind of insight that makes you want to root for them. The product is lean, the mechanic is simple, and honestly? This is the kind of obvious-in-retrospect startup that makes you wonder why no one built it sooner. It's low-key incredible as a product wedge — every runner you know is already tracking their miles, so the hard part (getting people to obsess over stats) is already done.
