I'm also backed. I'm working on Squally, a PC game to teach low-level comp sci.

My two cents:

Other accelerators are under pressure to only fund companies that will be "top of their batch" come demo day.

This often means rejecting small projects, solo founders, and pre-traction companies.

However, Pioneer welcomes these companies with open arms. Make no mistake, it's still hard to get in. It took me ~8 months of sustained effort before I was accepted.

But once you're in, you're in the company of helpful people who are just as hard working and talented, and have access to valuable mentorship.
