Practice the decisions that built
(and killed) every company you know.
Branching decision drills based on real startup moments. You make the calls, you see the consequences, you score across product thinking, business judgement, and founder instinct. Two new drills every week.
Airbnb Survival 2008
You are one of three co-founders of a year-old marketplace startup. The product lets travellers pay to stay in strangers' spare rooms or on their couches — verified hosts, verified guests, your platform handles the bookings and takes a cut. Two of you are designers; the third is the engineer who rejoined the team two months ago after a brief detour at another company.
