From you own point of view it is much better to be the only boss - share nothing, nothing special. From the point of view of any investor, investing in a single-founder is a much higher risk. In case of any accident the second founder could be of some use, where in a single-hero case it would be a guaranteed lose. Another issue is that smart investor would try everything in his power to engage all co-founders in a competition, a standard manipulation about position and respect. Very useful technique. So, it seems possible to do things alone, and a lot of people do, but investing in a single-founder startup is too risky - there is a single point of failure.)
