About Knot
Knot’s mission is to empower consumers and businesses alike with connected merchant and banking experiences. Knot is like “Plaid for merchant connectivity.” We are building the platform connecting merchants to the many applications that consumers and businesses interact with everyday. Our flagship CardSwitcher product allows consumers to instantly update & manage their cards on file with online merchant accounts (e.g. Netflix or PayPal). Newer products like TransactionLink support the retrieval of item-level transaction data, while Shopping enables native purchasing and checkout capabilities for any app. We are building many new products on top of our novel merchant connectivity platform and we hope you choose to come build them with us!
Founded in 2021, Knot was founded by two brothers and Thiel Fellows - Rory and Kieran O’Reilly - and today powers connected online payment experiences for hundreds of thousands of consumers. Companies like American Express, PayPal, OnePay, Current, BILT, Step, and more choose to embed Knot’s SDK in their apps to power best-in-class experiences for their customers.
Knot is proudly backed by a select group of investors, including Nava Ventures, 8VC, American Express, Plaid, and co-founders & CEOs of prominent companies like Twitter, Warby Parker, Allbirds, Casper, Intercom, Deel, Italic, DraftKings, and many more.
