CRB

CRB (Cross River Bank) is a New Jersey-chartered, FDIC-insured bank and financial technology infrastructure provider founded in 2008 and headquartered in Fort Lee, New Jersey.

Cross River is known for powering leading fintech partners including Stripe, Coinbase, Affirm, Upgrade, and Intuit, and was surfaced in the API Evangelist network as a Battery Ventures portfolio company.
