I hear you, and I appreciate the advice. There is a vesting cycle that's yearly, but ultimately it all depends on them selling them the company a few years from now (2023 or so).

While I fully expect them to sell, I expect them to stab me in the back so hard that the shares are effectively worthless.

I've been learning ruby in my spare time, so hoping to transition to a job that uses that in their stack eventually. I think I'm going to take a long break though, I'm very burnt out from the entire experience.
