I ran into the same issue. Of all the people I've met who end up being successful startup founders I never guessed correctly they would end up successful (a couple even became unicorns) and the cofounders I picked turned out to not so great.
From my experience ex-FANG guys are helpful when it's time to raise money but they rarely have the skills needed in a startup environment.
My approach now is to partner up with people I have a lot of history with and that I know they get things done, even if they're all technical. We're figuring out how to become the founders we need.
We are also not a fan of the entire "startup", high risk, high reward thing. It's too much risk, hassle and stress and you can live comfortably with a smaller profitable business.
