Paul Graham is a great guy but he is now more an investor than an entrepreneur (or at least that is how he functions with Y Combinator). We should therefore realise that when he says that he prefers to invest in companies with more than one founder, he is saying this from the perspective of an investor.

And from the point of view of an investor, it makes a lot of sense to have more than one founder. You invest about the same amount as you would with a single founder business but you get double or more the passionate people working desperately to make the business work.

From the point of view of a founder, however, things are very different. Get in a cofounder and you have immediately halved your stake and possible payout. You have also lost a lot of control. You are no longer in complete control of the company - many decisions now has to vetted by your cofounder. Not necessarily a bad thing but there is something to be said - from a self-actualisation perspective - for having complete responsibility for your destiny.
