Yeah, for one of the startups I founded, my mantra was "build a great business and a great product". But I didn't think I had the bandwidth to do both, I wanted help on the business side so I could focus on the product, so I hired a team to "build a great business".

But I wish I had read the bits about cofounders and exec teams.

The number of pitched battles I had about management processes in my pre-revenue, pre-customer, barely-there startup took so much of my time, while I was just trying to get the product out the door so we could sign people up.

I definitely chose the wrong parters... and it definitely sunk the company.
