Yeah sure. We initially wanted to build something to compare the equivalence of two programs written in different languages and for this we started out using KLEE. Unfortunately, we found it didn't quite satisfy our needs and then changes we wanted to make didn't really fit with their architectural model. We also felt like it wasn't as amenable to parallelisation as we would have liked. The core technology is using an SMT solver just like KLEE, but our hope is that Symbolica will be more scalable and easier to use for larger problems.

DeepState looks interesting, we had seen this before and other stuff from trail of bits, but admittedly we haven't used it ourselves. Our impression is that it seems like more of a frontend to various symbolic execution / fuzzing backends. So maybe it's something we should consider integrating with too.

We hadn't come across ForAllSecure before, so thanks for pointing them out. They do appear to be similar, but their focus seems to be on large commercial/enterprise projects in sectors like defence and aerospace. So maybe I'm wrong, but I don't think they have an offering for individuals / smaller teams.

On the logo point, as another commenter pointed out it's the mathematical forall symbol, so I guess we just both had the same thought when it came to coming up with a logo.
