Mistake. A "co-founder" with what sounds like ZERO experience that is shy to do sales and get his hands dirty is almost certainly going to be a failure. These type of people are a dime a dozen and it sounds like you want to bring him in just cuz you like his personality. BIG MISTAKE. If you ask me, bring in another technical guy and/or pay someone to help you with some market validation via sales (or do it yourself) Trust me on this (you probably won't).. i've learned this the hard way. I've been a solo founder three times in both successful (30k customers) and unsuccessful startups.
