You are not alone. ;)
I got burned last summer by bringing people on board too early. I'm the hacker-type.
The other people were the kind whose strengths too were different from mine. One was a high-powered client-interfacing guy, who has since taken a full time job as an IA, after the failure of his own Web 2.0 startup (all in under a year!). The other, and the troublemaker, was a high-powered marketing person who wanted to fasttrack the branding campaign before I even had a product or clients. We'd all worked together well in the context of a larger company, but we couldn't reconcile our directional aspirations for a startup.
So this year, I'm alone. In Northern Virginia's technology corridor. I would love a hackerly co-founder, or at least someone to bounce my ideas off of. All my friends from CS classes keep moving to the West coast to work for the Googles and Microsofts of the world. I have a feeling my YC application this year is going to be rejected simply because I'm a sole founder.
The application certainly makes it seem that this is the case.
I suspect this YC app field sends you to /dev/null. In the html, the select's name is "badness" !
It could be fairly interesting to see if a couple of technical people, working on different products, could act as one company. Both parties get the benefits of having someone to look over their shoulder (as they have a financial stake). You also get the sum of both sets of secondary skills and contacts. The downside would be a split in focus, but that should be no worse than the two working individually.
Kind of a more-intensive, tech version of the Tuesday Night Music Club.
First rule: no bringing your girlfriend, even if she is Sheryl Crow.
