Chime is dedicated to helping our members lead healthy financial lives. That’s why we offer an award-winning bank account that doesn’t charge unnecessary fees, gives members early access to their paychecks, and helps them save money automatically. Hundreds of thousands of people use the Chime mobile app and debit card to make purchases, track spending, save for the future, and more. Our members love Chime and use it daily.

We believe the big banks fail to help their members achieve financial health - and in many cases work against it, charging hundreds of dollars in hidden fees and pushing products that drive people into debt. We don’t think it needs to be this way, so we’re out to beat them.

We have one of the most experienced management teams in Fintech. We have raised over $100M in funding are backed by Menlo Ventures, Omidyar, Crosslink, and others.
