Knot

Knot is a New York merchant connectivity platform that lets banks, fintechs, and card issuers move their customers' cards on file across hundreds of online merchants - automatically. Through APIs like CardSwitcher, TransactionLink, AccountUpdater, and SubscriptionManager, Knot helps issuers win the top-of-wallet spot, cut payment declines, and surface SKU-level spending data, all without users manually re-entering their card details at Netflix, Amazon, PayPal, and more.
