We’re on a mission to unlock more rewarding relationships between merchants and their customers, starting with changing the way we pay for things online. Backed by Sequoia, Index Ventures, and Forerunner, as well as the founders of Affirm, Warby Parker, Allbirds, Casper, and DoorDash, Catch is a new payment service that allows both merchants & consumers to save money by cutting out credit card processing fees. Everyone wins – except the big banks. We’re a fully distributed, tight-knit team with hubs in SF, NYC and LA. Building a diverse team is paramount to our success and fostering a healthy company culture, and we’re committed to an equitable interviewing process for all candidates.
