AI tools is the most crowded category on the site, with the highest variance in outcomes. Half of these founders got to $10K MRR in under three months on a thin wrapper, then watched the underlying model shift and lost half their users overnight. The other half built defensibility into the workflow — vertical-specific data, integrations, domain-specific UX — and grew more slowly but kept their users. The playbooks below show both patterns. Look for the unfair advantage section: the durable winners almost always had domain expertise that the model alone couldn't replicate. If you're building in AI and feel like everyone is shipping the same thing, the data here points to the moves that compound past a viral launch — and the ones that decay the moment GPT ships an update. The first 100 users is the easy part. The next 1,000 is the question.
