This is a _profoundly_ bad idea. Cofounders should have a strong personal relationship before they start a company. They need to actually _know_ and _trust_ each other. I'd rather start a company without a co-founder than bring in someone I don't know as an even remotely equal partner.

Most people are in Startup School haven't even started or have no idea. SUS is a perfect place to start on a small project with other people. From our experience at YC, getting a cofounder is the single best thing to improve the odds of your startup.

That could be at the same time true on average and not true for the specific case where the founders don't know each other all that well (and therefore don't trust each other much more than you'd trust a stranger). If you have stats on the latter case, I'd be curious to see them. If not, consider collecting the stats from this experiment.

Maybe people are "good by default" and all that, but I do have some very early stage startup experience (VPEng), and both the founders and the employees have enough trouble trying to not get screwed even without such additional complications. Money and egos always find a way to ruin everything.
