I certainly plan to wait until I find someone that seems like a good fit. But once I get past "developer-heavy" phase of building a prototype I'm going to need someone to help grow my company- and quick. At that point it seems far-fetched that the "perfect" partner will materialize. I may have to settle for merely "good". Perhaps I'll make it past the point of needing a cofounder at all and will instead be able to go directly into hiring salaried employees. Of course, getting this far on my own would also be pretty lucky.
