About the Company

Chime

Runs a mobile banking app with no monthly fees

Chime runs a mobile banking app for everyday Americans, with accounts held at federally insured banks and no monthly or overdraft fees. It made its name by releasing direct-deposit paychecks up to two days early, and in 2019 it introduced SpotMe, which covers small overdrafts without a fee. Members spend with a Visa debit card or the Chime Card, a credit card backed by their own deposits that builds credit, and get part of their pay before payday through MyPay. Chime makes most of its money from the swipe fees merchants pay when members use its cards, plus charges and interest on instant transfers, pay advances, and small loans. Chime was founded in 2012 and is based in San Francisco, California.
