Protect the person behind the transaction.

Coffr, LLC is a company focused on one narrow problem: the unprotected exchange of bank details that sits underneath nearly every B2B payment.

Every year, businesses lose billions of dollars to a single failure mode. A finance team receives an email, from a real vendor, or one that looks close enough, with new bank details. They update the record. The next invoice pays a stranger.

The mechanism is not sophisticated. It works because the layer underneath it, how two companies exchange the numbers that route a payment, was never designed to be verified. Voided checks travel as PDF attachments. Routing numbers get pasted into email bodies. There is no signature, no provenance, no way for the receiving side to prove what was sent.
