You're right; execution and defensibility are much more important than merely having an idea. One thing I’ve learned is that a good moat often comes from distribution, community, or even data feedback loops more than tech itself.

I now focus less on what no one has ever done and more on what people have done, but can be improved for a specific group. Niching down creates natural defensibility.

I Would love to hear more about your approach to building a moat if you're ever up for a brainstorming session!
