“jFloat users come together and pay the majority of their premiums into collective pools of 100 people called “floats,” which consist of extended family members and like-minded people who fill out a survey on the company’s website. The cohort can approve or deny people membership. When a member needs to pay a claim that’s below a certain amount (which founder Kim Miller would not share), the money comes out of that pool. About 80 percent of a member’s premium goes to the pool, and 20 percent goes to a reinsurer – insurance purchased by an insurance company – to handle claims that go over the maximum amount. Miller would not share reinsurance partners.
