It sounds like you moved from a tech co-founder to a biz / tech founder. Is this a fair summary? Would be curious to hear more!
There are a lot of good resources about the biz side of things for consumer internet startups, so learning about that has not been too difficult.
However, I do try to hire more out-going people to complement me. IE, I push my team to connect with people at meetups more than I push myself :P
There are talented people out there and I've found it is possible to recruit those who complement me without making everyone co-founders.
Once the startup has gotten some traction, recruiting and everything else get easier. If you have a tech background yourself, you may not need co-founders to get to that stage.
Thanks for the positive response!
