I built a thing today, The Niche AI Playbook. It's an intelligence report and interactive tool that makes the case for going vertical in AI. The short version: horizontal AI apps are in a race they can't win. The same labs powering your product are also your biggest competitive threat, and every model update commoditizes another layer of wrappers overnight. The data is pretty clear, vertical SaaS is growing 2.5x faster, CAC runs 40-60% lower, and churn is dramatically better because you're embedded in workflows people actually depend on. The hard problem in AI has shifted from how do I build it to what do I build, and the answer is always narrower than you think. Go run the niche positioning tool and find out if you're building a moat or a wrapper.
