I've been a single founder since 2005 and I can relate to these findings.

Some parts of my business are on a complete auto-pilot and will continue to function even if I'm not around. The main part of it though, won't. That's the problem I see with my solo ventures.

I'm currently looking to automate what's left of the business processes so that I don't lose the company due to unforeseen circumstances. Not sure if I'll succeed.
