You are not allowed to offer any type of equity in your venture in exchange for support, or any expectation or future financial return (so no revenue splits). StartSomeGood is a donation-based crowdfunding platform.
Other no-nos: loans, lotteries, raffles, sweepstakes, and coupons/discounts on future goods or services. Like a chaperone at a middle school dance, we don’t make the rules, we just enforce them.
