Is 99% of the market wrong? A new AI startup playbook: serve only the top 1% of experts

Take chess as an example. We all assume the market must already be filled by the biggest chess-playing websites, and newcomers have no chance.

But a chess grandmaster went out and started his own company. He said the big site serves casual players like us, the 99% of ordinary people.

For the world’s top professional chess players, however, the tools on that site are basically unusable.

What do professional players need? They need to immediately search all the “Sicilian Defense” games a given opponent has played over the past ten years. When watching live matches, they want deeply professional data analysis, not beginner explanations.

So he simply built a platform only for professionals. He never intended to serve ordinary hobbyists like us.

That move is brilliant.

It is like opening an ingredients store that only Michelin chefs can enter. If you first serve the pickiest and most influential 1% well, the remaining 99% of enthusiasts who want to learn something real will desperately want in.

At that point, what you are selling is no longer features. You are selling access to a circle.

Looking across these examples, you will find that the technology itself may not be the most important thing. What matters is whose problem you use it to solve. Are you solving the future cost problem of infrastructure, the efficiency problem of how we get information, or the professional problem of top experts?

That is far more valuable than empty talk about AI changing the world.
