I am a founder and also a software engineer. When I have my founder hat on, our dev team doesn't always like it because I will be like "people, we need to build this feature fast. Sorry I can't give you the whole wireframe. let's figure this out together based on the high level scope I can provide for now and we will figure it out". That's tough but in a startup, we gotta ship. The worst part: we will sometimes de-prioritize the whole thing after coding for a week. It is suddenly not that important. I try to not do it all the time but it happens and I would rather do it than not. Thoughts ?
