The moat was never the model.
It's the boring distribution, the workflow you slot into, and the data nobody else has.
I learned this the hard way with DocsGenie — a gorgeous RAG demo that solved a problem people didn't pay to solve. WhatsBoard is uglier and far more useful, because it lives inside a workflow people already run every day.
If your product dies the moment the model gets 10% better, you didn't build a product. You built a feature.
