Born from a 2018 effort by Ezra and Jacob to stop students from losing dorm keys, Keyper makes silicone phone wallets that combine a card pocket with a snug key holder. Rayna joined the team in 2019, and the company now produces custom-logo Keypers for organizations and collegiate designs sold through more than 300 universities. Its patent-pending product has surpassed 100,000 custom Keypers made.
