About Affirm

Affirm was founded by PayPal co-founder Max Levchin with the goal of offering customers fast and easy access to financing purchases on the internet. With the core of the financial infrastructure built using technology from the 1970s, Affirm believes the financial industry is in desperate need of reinvention. Affirm's mission is to fix this problem. They use modern technology to re-imagine and re-build core components of financial infrastructure from the ground up. The result: less expensive and more transparent financial products.
