It wasn&#x27;t a very important comment, but I would say that there are some people who get a &quot;high&quot; from collaborating with many people on problems (working really hard with a small team), and some people who get a &quot;high&quot; from learning things on their own and applying them, with the help of experts.<p>One person you could take as an example is the Pinboard founder.  If you read all his blog posts, I wouldn&#x27;t call him a &quot;collaborative&quot; person.  Is he a highly intelligent, productive, and respected member of society?  Yes.  Collaborative?  No.<p>My impression is that cperciva is like this, but I could be wrong.  I&#x27;m more like this too, as mentioned.  But you still need community if you&#x27;re in this camp.<p>I think there is potential for higher overall growth when you have the right team, simply because there are too many things for one person to do, requiring many different types of expertise.  Though there is not necessarily higher &quot;per capita&quot; return.<p>But growth compounds, so that explains why YC prefers co-founders over solo founders.  But YC also acknowledges that there is a big downside to working with teams: co-founder disputes are one of the biggest, if not the biggest, reason for startups failing!
