They kicked off by locking down retention before chasing growth. For the first 20 weeks they never ran a single acquisition campaign until weekly retention hit 90 percent. That meant fixing every user leak early. They tuned their product and experience so people came back on their own, rather than pouring money into ads and hoping for the best. Every step was grounded in hands-on learning. The founders spent hours on personal onboarding calls with their first 50 users. They stuck a credit-card wall on day two to make sure people were actually willing to pay. Instead of polishing a perfect app in isolation, they launched a rough version to 30 users within a week. Every feature request and bug fix came straight from real conversations, not from an ivory-tower roadmap. They stayed small, deliberate and data-driven. Headcount stayed at two for far longer than felt comfortable. Every Friday they shipped code. They tracked burn rate and runway on a whiteboard each week, aiming to be “default alive.” They fired misfit customers early, choosing ten super-fans over a thousand lukewarm users. Honest conflict between co-founders was non-negotiable—speed of resolving problems mattered more than politeness. That discipline got them past three near-deaths and into 1,000 paying customers.
