If they are Delaware C corporations and you own at least one share, you have a legal right to demand access to the cap table.

It was registered in Delaware but it was an LLC.

I'm not a lawyer so I don't know if an LLC would have to comply in the same way.

I do know that there was an operating agreement and we had a very strange meeting at one point where the CEO and the financial guy told us that we had the right to see the operating agreement. Someone who left shortly after must have hired a lawyer and demanded that.

I did see it the operating agreement but not the cap table. When I left the company I did not even know what a cap table was so didn't even know that it was a thing that existed. I only found that reddit post a year later. I'm post that link so that people don't make the same mistakes I did. There were a lot of other questions I should have asked before joining both startups.
