I started a business in college, by myself, and it had revenues of about 6 million by the time I hit 25. I'm now 30 and on my second business, which I also started and am now running by myself. Why don't I elaborate on some upsides to your little list? * You are the only one. That means if something goes wrong, you can't shift the blame. Not even subconsciously. It's always your fault. This guarantees problems get fixed and they get fixed fast. * You are the only one. That means you don't have to get approval or dilute your ideas. It gets implemented. Now. If you're spouting bullshit, the market will filter and you will adjust, fast. * You are the only one. You have to do everything. That means you understand every aspect of your business, because at some point, you did it. This helps you make effective decisions. * You are the only one. etc etc etc You get the idea. I can go on forever and you can go on forever listing wonderful things about co-founders. One way isn't better than another. They are different and the path you take depends on your goals. If your goal is to build a business that grows into hundred-million+ entity so you can cash out or where you can garner a cult following (i.e. Steve Jobs/Bill Gates/Larry Ellison/etc), you need a co-founder. On the other hand, if you want a business where you can pour your unmitigated passion into, where it becomes a place that not only supports you, but where your ideas take form, a co-founder will just get in your way. To dumb it down, if the #1 goal on your list is money or status, bring somebody else on. You won't be able to compete by your lonesome. However, if the #1 goal on your list is the freedom to do things the way you want to do them ... the only way to accomplish that is to remove as many obstacles to that as possible. That means no co-founders, no investors, none of it. A structure where you don't have to check with anyone before you do something. This, by the way, explains why most investors are completely against companies with no co-founders. It's not in their interest. The goals of the company do not align with their goals.
