Lesson from a failed startup: the real problem is marketing, not building

A solo founder reflects after his last startup got zero traction despite going exactly as planned technically, and commits to a different approach next time: build something that solves a real problem. He identifies what he sees as the actual bottleneck for most solo founders — not building the product, but finding early users afterward. Building has a clear finish line, but finding the exact group of people on the internet who need your product does not.

Founders keep searching blindly until they either get a result or, more often, give up quietly after not trying long enough, convincing themselves no result exists. As a consequence, many never actually find out whether their product could have succeeded, simply because they lacked the reach or know-how to find the right users.
