If you are building an MVP, and you’re pre-seed, pretty much everyone is working for free so don’t ever try and get all the details right.
Detail work for just about everyone, is drudge work.
Tweak that other thing.
You want to burn through developers faster than you can convince them to work for free?
Give them drudge work.
You want your developer to stick around?
Give them interesting problems full of green field code and they’ll stick around (and make fast progress) almost indefinitely.
You’re building an MVP, the moment you try and make any one detail perfect, you’ve immediately failed at building your MVP.
