I am not sure this is true. If so, we'd be building a world that serves people who start tech startups and leaving out huge markets of people who are not this customer. Instead, I think you need to understand whether there's a real opportunity. If you have the problem yourself, that's one data point, but it is also possible to have humility and learn from other people who have needs. What doesn't work is trying to serve people who aren't you and also you don't listen to or understand.

Possible, yes. Although, it will cost you lots of time and money getting what you need second hand. Those 'other people' don't care how much runway you have, or when your next release is, or what meetings you have coming up. They WILL slow you down. Succeeding with a startup is a game of squashing risks, and that's a massive risk to have out of the gate.
