Credit unions might be about to eat big banks’ lunch in the business banking world.
And according to new research from Cornerstone Advisors and Nymbus, it’s not just wishful thinking — it’s a genuine, data-backed opportunity sitting there like a piñata waiting to be cracked open.
The report, titled “Winning the Business Banking Market: A Strategic Blueprint for Credit Unions,” surveyed 1,249 business owners and senior executives. The headline stat? Eight out of ten would seriously consider jumping ship to a financial institution that actually builds products for their specific industry. Not “sort of works for them.” Not “good enough.” But actually designed with their business in mind.
Right now, credit unions serve as the primary business banking provider for just 5% of the market. That’s a rounding error. But here’s the kicker — most credit unions are operating way below their member business lending caps. Translation: they’ve got capacity to spare and a market that’s practically begging for alternatives.
The Big Banks Are Vulnerable (And They Know It)
Nearly half of the businesses surveyed said they’re somewhat likely to switch their primary banking provider in the next year or two. Twenty percent are already actively looking. These aren’t loyal customers — they’re hostages waiting for a better option to show up.
“Businesses in this segment are not loyal to the big banks. They stay because, until recently, they had no real alternative,” said Ron Shevlin, chief research officer at Cornerstone Advisors and the report’s lead author. “That is the opening for credit unions. The ones that build genuine expertise in a specific industry, and back it with the right digital experience, will offer something the megabanks and the fintechs cannot easily copy.”
Shevlin makes a crucial point: anyone can match interest rates overnight. But deep industry knowledge? That takes years to build — and it’s a competitive moat that actually holds water.
What Businesses Want (Hint: It’s Not Complicated)
The report identifies what it takes to win these business customers, and spoiler alert — it’s not rocket science.
First up: digital experience. A whopping 41% of businesses said a digital platform that’s as good as or better than their current bank’s is the number-one requirement for making the switch. Nobody’s asking for bells and whistles here — just a banking platform that doesn’t feel like it was designed during the first Bush administration.
Second: actual industry expertise. Three-quarters of businesses find it believable that a credit union could develop deep knowledge of their specific industry. But the report is clear — this means more than slapping together a few generic products and calling it “industry-focused.” We’re talking distinct brands, dedicated expertise, sector-specific go-to-market strategies, and technology that can actually support all of it.
The All-in-One Platform Dream
Here’s where it gets interesting. Nearly three-quarters of respondents said having banking, payments, invoicing, cash flow forecasting, and accounting and payroll integration in a single platform would be extremely or very valuable. A third would consider switching financial institutions just to get it. And more than 7 in 10 said they’d actually pay for a platform that reduces the time and complexity of managing their business finances.
Translation: businesses are drowning in disparate systems and they’re willing to vote with their wallets for someone who can simplify their lives.
Michigan State University Federal Credit Union (MSUFCU) gets it. They built their business banking brand, Pillur, on exactly these principles, using the Nymbus platform to focus on what business owners actually use day-to-day.
“We wanted to make sure we had both a product mix and an actual service mix that made it usable,” said Ami Iceman-Haueter, MSUFCU’s chief experience officer. “You can do the day-to-day management of your business from our platform without needing to log in and out of several different systems.”
That’s not a feature — that’s a legitimate competitive advantage.
The Nine-Part Blueprint for Success
The report doesn’t just identify the opportunity — it lays out a nine-part blueprint spanning strategic, go-to-market, and technology initiatives. Key recommendations include:
- Pick a single vertical and build genuine capability to serve it (not surface-level lip service)
- Convert existing member business owners before chasing shiny new prospects
- Lead with cash flow management instead of loans
- Choose technology actually built for business banking, not consumer cores with business features awkwardly bolted on
“This research confirms what many of us already sense: business banking is a massive opportunity, and credit unions are well-positioned to capture it,” said Jeffery Kendall, CEO and chairman at Nymbus. “The opportunity is real, it’s sized, and it’s winnable. My call to every financial institution leader: stop letting legacy cores hold you back, and start treating business banking as the strategic priority it is.”
The Bottom Line
The small and midsize business banking market is underserved, frustrated, and ready to move. Credit unions have the capacity, the community trust, and now a clear blueprint for winning. The real question isn’t whether the opportunity exists — it’s which credit unions will stop treating business banking like a side hustle and start building something that actually competes.
Because the businesses are ready. The question is: are the credit unions?
