Column is a nationally chartered bank that operates its own developer API, so the entity holding deposits and the entity serving the API are the same.
It offers bank accounts, a ledger, ACH and wire origination with direct Federal Reserve access, card issuing with BIN sponsorship, and loan origination. Because Column is the bank, onboarding runs through the bank's own risk and compliance process.
