One Banking Relationship. The Full Fintech Stack.
Issuing, acquiring, lending, and embedded finance. Programs that work better because they share a foundation.
Let's TalkCard Issuing
Celtic is one of the largest issuers in the United States, operating across Visa, Mastercard, and American Express with a partner roster that includes some of the most recognized names in fintech. We know what complex programs look like and what it takes to run them successfully at scale.

Merchant Acquiring
Celtic's acquiring program is built for ISOs, PayFacs, and platforms with established portfolios and proven vertical expertise. We don't hand you a list of approved categories. We talk about merchant risk directly with partners who know their business. Fewer surprises, more durable programs, and a growth-oriented bank that excels at navigating complexity.
Embedded Finance
Accounts, lending, disbursements, and the broader suite of financial services modern fintechs need to fully serve their customers. Our embedded finance programs complement our issuing and acquiring programs — giving your customers access to the full financial services stack through a single banking relationship.
Lending
Celtic is one of the most experienced consumer and commercial lending partners in fintech — powering credit card programs, point-of-sale financing, term loans, and revolving credit for some of the most recognized names in the industry. For partners building lending into their platform, we bring the regulatory infrastructure, underwriting expertise, and scale to match.

Not a platform. Not a vendor. A bank built for operators.
