Ive been investigating the grunt fund [0] concept lately and plan to use it with my current startup to bring on a partner. I think it would go along way to ease your concerns.
Not sure why this got downvoted, I didn't know about this book / site and just spent an hour watching a talk he gave at Stanford (he posted it on his site). I see some problems with his method but it looks like a step in the right direction.
I probably got downvoted because i failed to mention im not affiliated with this concept so it appears as though im self-promoting. So just to be clear i have no affiliation with it and just learned about it last week and read the book over the weekend and think this approach has a lot of merit.
