Let's push them to disclose the amount of equity, and if it's pre or post money SAFE, etc. I'll try to email them, not an expert but have a bit of experience with a few trad startup accels including YC.

It's on-site only the first 8 weeks I'm guessing? It's not entirely clear, but if it's the case then I don't think it's too bad.
