Hey, It's not necessarily more a deterrent than giving cash back. 1. we are not yet legally allowed to give money back to our users (but we're working on it) 2. some behavioral economic theories actually suggest that cash is less an incentive than other more altruistic incentives. Once our give back to consumers will be active- I'll guess we'll be able to put our theories to the test- hope this answers your question
Mutual insurance companies exist in New York. Are you not legally allowed to give money back solely because you decided to incorporate as a benefit corporation?
