The card hasn’t launched yet, but the startup claims they’ve added 150,000 people to the wait list, in part because of the incentives to refer new business. It’s set to launch in 2018.

Zero says that the bank it’s working with is FDIC-insured and Galen insists that it has “structured the product very carefully in order to be fully compliant with all rules and regulations.”
