Build the world’s fastest Identity and Checkout products

Company Mission

Our mission is to make buying online faster, safer and easier for everyone. Fast Login and Fast Checkout enable a one-click sign-in and purchasing experience that makes it easier for people to buy and merchants to sell. The company’s products work on any browser, device or platform to deliver a consistent, stress-free purchasing experience. Fast is entirely consumer-focused and invests heavily in its users’ privacy and data security. Headquartered in San Francisco but open to a globally remote workforce, we are a founders-led, privately held company funded by Stripe, Index Ventures, Susa Ventures and other world-class investors.


We want to simplify integrations for merchants both on and off e-commerce platforms to unlock Fast Products that have not been available outside of the Fast ecosystem.

External Integrations helps Fast rapidly expand our network of merchants. We started the Fast Checkout revolution by enabling merchants on BigCommerce, WooCommerce and will be expanding to a lot more, and quickly! This team owns the services which help the Fast domain logic talk to external partners. Whether that be at a platform level like BigCommerce and WooCommerce or how Merchants directly integrate with Fast using Fast API’s, and/or SDK’s. This team also owns how we get Updates from any of the merchants on their orders and the infrastructure behind it.
