I think you already know the answers to many of the questions you've asked here (including the post title, which can be easily answered with a 'Yes' with several examples).

I am a single founder. And without going much into the topic itself, I would suggest:

1. Several accelerators and investors play safe, and common world statistics go against single founders. These accelerators are not the ones to blame for it.

2. You have to convince them that you're an exception to the common statistics they see everyday.

3. A good way to do this is to show that you can build a worthy team (but I guess you're not yet at that stage).

4. You didn't make Point 2 happen with this accelerator. Try again, elsewhere?
