So you want to be a founder … but you’re not the “idea” guy?
It’s OK. This happens all the time.
Don’t look for ideas, then. Look for an idea co-founder. Look for someone that lacks your skills (engineering, sales, marketing, whatever you are good at) that is hyper-creative and can create something from nothing.
Usually it’s really just one person on the founding team that really has the “idea”. The others refine it. That’s ok. One is enough.
