Sponsor Bank 101: Everything Fintechs Need to Know Before Signing a Contract

Banking as a service, community banks, and fintech partnerships are changing how small businesses access financial products. Tedd Huff, CEO of fintech advisory firm Voalyre and founder of Fintech Confidential, along with Stephen Bishop of amBaaSsador and Fintech Confidential, Confidential Informant, sits down with Lindsay Borgeson, President of Partner Banking at Core Bank, to unpack how a community bank in Omaha, Nebraska built a full BaaS platform from scratch without a top-five bank playbook to follow.

The BaaS space has had its share of high-profile failures. Consent orders, compliance breakdowns, and program manager implosions have made headlines for all the wrong reasons. Core Bank took a different approach. They spent time reading every consent order before writing a single line of code. They went to their regulators, both the FDIC and the state, before building anything. They presented their strategic plan, invited regulators back multiple times outside of formal exams, and built a reputation for transparency before they ever onboarded a single fintech client.

"We are not the biggest name in BaaS," Lindsay admits. "Yet, we certainly aim to be a well-known, respected name, but for the right reasons."

That mindset shaped everything about how CoreX, their BaaS brand, was built. They did not try to bolt new capabilities onto an existing tech stack with bubblegum and duct tape. When their initial technology partner did not work out, they stopped, went back to the board, and interviewed over ten vendors before selecting Core Bank as their Side core and Oscilar for transaction monitoring. They later added Cobalt Labs for AI-driven compliance workflows. Each decision was made with long-term strategic alignment in mind, not speed to market.

The compliance model at CoreX offers two paths. Fintechs can choose managed compliance, where the bank handles transaction monitoring, KYB, and KYC. Or they can run customized compliance if they have the internal muscle to own those functions themselves. Either way, the expectation is the same: compliance is not a phase, it is a constant. Lindsay puts it simply: "Compliance first. I should probably consider removing it because it's compliance always."

What makes CoreX different from other sponsor banks is the focus on who they want to serve. Their ideal customer profile centers on fintechs that support small businesses, particularly vertical SaaS platforms in industries Core Bank already understands. Construction, real estate, property management, unions, aviation, medical, and hospitality are all sectors where the bank already has deep expertise on the traditional side of the house. That knowledge transfers directly into how they evaluate fintech partnerships.

The "dinner test" came up more than once. If you would not want to sit down for a meal with a potential partner, you should not get into a contract with them. When things go wrong, and they will, the quality of the relationship determines whether both sides can work through it or walk away bitter.

For fintechs considering a community bank partnership, the advice is direct. Know what matters to you before you start talking to banks. Do not compromise on compliance or risk management just because someone promises speed or a lower price. And if a bank says they can have you live in three months and profitable in twelve, something is off. Building this correctly takes time.

For community banks thinking about entering BaaS, the message is just as clear. Do not dabble. This is not a side-of-desk project. It requires dedicated people, a separate tech stack, a documented risk appetite, and full alignment from the board down. If your executive team is not excited about it, you will not have the patience to do it right.

"It's not for the faint of heart," Lindsay says. "But it is really a great avenue for community banks to thrive."
