I have always been curious about a different approach. Let's say that I interview you and a few other people, and then match you in a party with someone whose skills and character are complementary to yours. Then I match both of you with an idea that suits your party's combined skill set and also has a chance of making money. You're welcome to pivot and try something else after reasonable time and effort was put in. Everything else is boilerplate like 49/51 equity split and vesting schedule so you can focus on delivering maximum value.
