I'm a single founder and can only say the experience is rather grinding.<p>I'm all up for the "If you don't help, at least don't get in the way" motto. I decided to pursue my current venture without a cofounder precisaly because I didn't find enough people that had both the skills and (understandably) the willingness to quit their nice paying jobs.<p>For me, it doesn't really make sense to have people aboard unless they add some real value to the two core functions of what a startup needs to do: building something and sell it. It's fine if you can't build it, but you better be damn good at selling it. Photo ops and "vision, mission and values" statements don't really justify a position on a bootstrapped startup that's trying to get a product out (this obviously varies, having well connected co-founders may make a lot of difference, some people are well worth their pay just because of their business karma).<p>The big problem of a solo venture, IMO, is that you find yourself doing these two roles simultaneously, which can be exhausting. It is for me, at least. I can do both rather well, but after a while I start finding it difficult to focus on designing a system for scalability, designing its database, reflecting on security, writing and testing Android code, building prospects lists and getting their contacts, getting meetings and attending them, fine-tuning your sales pitch and getting the man to write out a check. And I left out all the menial work that still has to be done.<p>By the end of the day, you're in agony not only because of that feature that is taking too long to build, but also for not getting enough customer meetings, because of not having enough positive answers and, mostly, because launch is (or should be) just around the corner and there's still a lot of stuff to be done and no one except you to take responsibility for it.<p>It's an emotional rollercoaster, so having the right partner seems like a good move.
