Yep, it's incorporated. It's his idea, and he's driving everything, so I have no qualms with him having the lion's share of stock. I have plenty of my own useful experience I'm bringing to the table of course, and will be working in a mainly product, slightly technical role.

This isn't his first company (hence why I'm happy to follow along and learn from his experience), but the amount of equity offered seems very low. 0.013% of all outstanding shares vesting per month.

Thanks for the links.
