Sam Altman’s advice for solo startup founders

We prefer two or three person founding teams, but we are not religiously opposed to solo founders and we funded a number of solo founders that have gone on to be successful. Although in all of those cases they got a co founder at some point after we funded them. So I believe, like Dropbox and Instacart, at the moment we said yes to funding them. Didn't have a co founder, but either before our program started or quickly after, both of them did. We're not like totally opposed the issue. The two issues, One, there's like a lot of work and it's really hard for only one founder to do it. And two, is that the psychological toll of being a sole founder? Even people that think they're really tough manage to underestimate this. So look, it's definitely possible. Although if you made a list of the sort of 10 billion plus dollar tech companies and looked at how many of those didn't have co founders by say six months in, it's a pretty short list. I guess it's definitely worse to have a co founder, to not have a co founder and then have a bad co founder. So what we really hate is when people bring on a co founder because they think we'll like it. That ends in heartache 100% of the time, literally 100% of the time. But I think start working on an idea without a co founder but never stop looking for one. If you're a solo founder and the biggest companies seem to generally have had two or three founders almost always, I actually can't think of a single one that had a real sole founder.
