The story

Fast was founded in San Francisco as an online login and checkout solutions company designed to provide users with a secure, frictionless shopping experience. The company raised through Series B before shutting down in April 2022 after failing to raise additional capital. The product focused on one-click checkout across merchants, competing with Shop Pay and similar solutions. There is limited public evidence of an active embedded finance stack beyond the core checkout product.
