Could you have built the giants?

We test AI on this benchmark — now it's your turn. Make the real, pivotal calls famous founders faced, or run your own startup quarter by quarter and try to reach product-market fit before the runway runs out. At the end: would you have done the right things to win?

Founder’s Gauntlet Build a Startup<br>Step into the founder’s chair<br>You’ll face a series of real, pivotal decisions from the world’s top startups — Slack, Airbnb, Stripe, Netflix and more — with the outcome hidden, exactly as the founders saw them. Every call moves your trajectory-to-PMF meter. Make the wrong ones and you run out of runway. How far can you get?<br>Choose your run<br>Quick5 decisionsStandard8 decisionsMarathon12 decisions

49 real decision points in the deck. Every run — and the order of every answer — is shuffled, so there’s no pattern to game. You start under-funded, and a couple of wrong calls end the run.
