The 80/20 Rule for Loan Growth Technology Decisions

Vector 3D pie graph or chart with Pareto principle – 80/20 rule. 80 % of outputs or outcomes result from 20 % of inputs or causes – effort and result.

Big banks spend tens of billions annually on technology. JPMorgan Chase alone allocated $17 billion to technology in 2024, according to its annual report. Community banks and credit unions operate with a fraction of those resources, yet some are proving that disciplined investment decisions matter more than raw spending power.^[1]

The Framework That Changes Everything

Benjamin Maxim, CTO at Michigan State University Federal Credit Union, articulates a decision framework that every community FI leader should internalize: if a partner gets you 80% of the way there in two months versus two years building internally, the math favors buying.^[1]

This isn’t a blanket endorsement of outsourcing. Maxim reserves building for capabilities that are “truly differentiating”—tools that don’t exist in the market or that the institution could develop more easily on its own.^[1] The key is honest assessment, not institutional pride.

According to the Conference of State Bank Supervisors’ 2025 Annual Survey of Community Banks, 75% of institutions under $10 billion in assets outsource core platform services, and two-thirds outsource customer-facing technology like mobile banking and automated account opening.^[1] The industry has largely accepted that commodity infrastructure belongs with specialists.

But loan growth technology? That’s where paralysis sets in.

The Hidden Cost of “Someday” Initiatives

Most community FIs approach prescreen marketing—FCRA-compliant firm offers of credit using bureau data—as a “someday” initiative. The regulatory complexity feels daunting. The credit bureau integrations seem expensive. The compliance requirements appear overwhelming.

So the initiative sits on a strategic plan, year after year, while competitors capture the loans your institution should be closing.

Consider the opportunity cost. According to TransUnion, total consumer debt in the U.S. reached $17.7 trillion in Q4 2024, with credit card balances alone hitting $1.21 trillion.^[2] Your members and customers are borrowing somewhere. The question is whether they’re borrowing from you.

When a megabank sends a preapproved credit card offer to your best member, they’ve already done the underwriting. They know that member qualifies. They’re making a firm offer backed by bureau data. Meanwhile, your institution waits for that member to walk in and ask for a loan—an increasingly rare occurrence in digital-first banking.

Applying the 80% Rule to Prescreen

Prescreen marketing is the perfect test case for Maxim’s framework. Ask yourself three questions:

Is this capability truly differentiating? FCRA-compliant prescreen campaigns require bureau integrations, compliance infrastructure, and regulatory expertise. This is table stakes for competing, not a proprietary advantage.
Could we build it more easily ourselves? Building compliant prescreen infrastructure means establishing credit bureau relationships, developing complex workflows, creating firm offer documentation, coordinating campaign execution, coding optimization, and maintaining ongoing compliance. For most community FIs, this is a multi-year project requiring specialized talent.
What’s the cost of delay? Every month without prescreen capability is another month of losing loans to competitors who are proactively targeting your members with firm offers.

The math typically favors buying speed. A partner with established bureau relationships, proven compliance frameworks, and tested campaign infrastructure can have you in-market in weeks rather than years.

What “Buying Right” Looks Like

Not all partnerships are created equal. Maxim’s experience at MSUFCU offers guidance on what to look for:^[1]

Negotiate early-adopter terms. Fintech partnerships work best when you can influence how the technology develops.
Retain control over customization. MSUFCU built its own digital banking platform partly because vendor options lacked flexibility and the per-user fee model would have become unsustainable.^[1] Look for partners whose economics align with your growth.
Demand API-based integration. Modern platforms with open architectures let you plug in solutions without overhauling your core—a critical difference from legacy integrations.^[1]

For prescreen specifically, the right partner handles the regulatory complexity while giving you control over targeting, messaging, and member experience.

Data Modernization: The Prerequisite You Can’t Skip

One caveat applies to any technology investment: data modernization is the unglamorous prerequisite that makes AI and automation payoffs possible.^[1]

Prescreen campaigns are only as good as your ability to match bureau data against your member file, segment effectively, and measure results. If your data infrastructure consists of siloed systems and manual exports, start there. The best prescreen partner in the world can’t overcome bad data.

The Differentiation Opportunity

Here’s what megabanks can’t replicate: your relationship context. You know which members have direct deposit. You know who just paid off an auto loan. You know the small business owner whose line of credit expires next quarter.

When you combine that relationship intelligence with bureau-powered prescreen capabilities, you’re not just matching megabank tactics—you’re beating them. A preapproved offer from an institution that knows you will always outperform a generic mailer from a distant brand.

Community banks and credit unions will never win the spending war. But disciplined technology decisions—knowing when 80% from a partner beats 100% built over two years—can close the capability gap faster than most executives realize. The institutions that apply this framework to loan growth technology won’t just survive the competitive pressure from larger players. They’ll take market share back.
