We are bringing a better way to send, spend, invest, and save to anyone who has ever sought an alternative to the traditional banking system.
Loved by customers and pop culture, we’ve consistently held the top spot for finance in the App Store for many years, seeing more engagement with millions of followers across social media in a day than most brands see in a year.
