OK, no. I appreciate the support for single founders, but this isn't a supporting argument.<p>> If books can be written by one person and become successful. Why can’t startups?<p>Because books and startups have nothing in common? Lots of successful endeavors are done by a single person, but that doesn't put the efforts of a single person vs. a team on the same footing, /especially/ as the problems increase in difficulty. Here's a better example:<p>"If children can be raised by one person and become successful, why can't startups?"<p>Sure. There are many children who have been raised by single parents and have become very successful. But that doesn't mean /statistically/, this is as easy as having both parents.[0]<p>The point that is being made counter to this is very simple: Yes, starting a startup can be done by one person. As can a lot of things. But statistically speaking, there are more successful startups that have multiple founders than single founders. You already provided the pie charts in support of this argument! Now to be fair, correlation does not prove causation, but the point is generally: Starting a startup is hard. Understanding the needs of your customers and both developing a solution to meet these need and reserving time to convince them that you've met their needs (selling) is very, very hard.<p>One of Ryan Carson's arguments (#2) was in essence that having no co-founders means you can top-down dictate leadership. I don't know about you, but I'm not always right. I've never actually met anybody who's always right. Having a team who's on equal footing with you allows you to vet concepts before they catastrophically destroy your company.<p>To paraphrase Chris Rock: Yes, you can do it without a [co-founder], but that doesn't mean it's to be done.<p>A good co-founder will almost always make your business more successful. And that's all there is to it.<p>[0] <a href="http://www.human.cornell.edu/pam/outreach/upload/parentalconflict.pdf" rel="nofollow">http://www.human.cornell.edu/pam/outreach/upload/parentalcon...</a>
