> help me determine what % of the company I'd be getting in this stage?
Just ask them what % of the company you'd be getting at this stage. They should absolutely tell you that; that's the high order bit of equity compensation negotiations. If they don't tell you up front they're wasting your time.
Early-stage startups need mutually trusting relationships in the team. If they don't trust you enough to tell you, or you don't trust them enough to believe their answer, equity comp numbers are not the issue here.
