My advice would be to team up with others in the VC/angel community. You may be the type that VC's like to put in as the CEO of a heavily technical group. If you don't have the technical savvy yourself, you may be putting your nest egg at serious risk.

In the past month there was a thread about becoming an angel investor. One of the key points was to spread your investment over 10 or so companies. Going that route improves your chances of finding a winner and finding a good fit as a CEO.

SV is a good move. There's a good community of like minded folks.
