According to PYMNTS.com, Zest AI has secured a strategic investment to expand its automation initiatives and scale its AI lending intelligence platform, LuLu. The company’s machine learning models enable lenders to achieve, on average, a 25% increase in approvals and a 20% reduction in defaults. Zest AI boasts more than 50 patents, 650 proprietary credit models, and nearly 300 customers, including credit unions and large banks. The funding round was led by Citi Ventures and credit unions like Truliant Federal Credit Union and SchoolsFirst Federal Credit Union. SchoolsFirst’s CEO stated the technology more than doubled their instant approval rate. Zest AI introduced its LuLu Strategy model in May 2024 and launched an AI-powered fraud detection solution in August 2024.

Why This Funding is a Big Deal
This isn’t just another tech funding round. Look, the fact that the investors are the customers themselves—major credit unions and Citi’s venture arm—is incredibly telling. They’re not just betting with someone else’s money; they’re investing in a tool they already use and see delivering real results. When a CEO says a platform “more than doubled” their instant approval rate, that’s a game-changer in the slow-moving world of finance. It means they’re approving more good loans, faster, without taking on more risk. That’s the holy grail for lenders.
The Competitive Squeeze is On
So what does this mean for the rest of the lending tech market? Basically, the pressure is now on for everyone else. Zest AI is using this cash infusion to scale up fast, and with claims of a 25% approval lift and 20% fewer defaults, the value proposition is stark. Legacy credit scoring systems and slower underwriting platforms are going to look ancient by comparison. The winners here are the financial institutions that can adopt this tech quickly. The losers? Any lender still relying purely on traditional FICO scores and manual processes. They simply won’t be able to compete on speed, efficiency, or risk management.
The Secret Weapon: Fraud Detection
Here’s the thing that often gets overlooked: the fraud detection piece. Zest AI’s CEO, Mike de Vere, said their AI can consume “trillions of points of data” to spot fraud patterns, which is “so far beyond where a human can be.” In an era of increasingly sophisticated financial crime, that’s not just a nice-to-have feature; it’s a critical defense. This capability, launched just in August, instantly flags income inconsistencies and both first-party and third-party fraud during the loan decision process. That directly protects the bottom line. It’s a powerful one-two punch: approve more good customers while simultaneously weeding out the bad actors more effectively.
What Comes Next?
With this war chest, Zest AI is positioned for a major land grab. The CEO cited “regulatory support for AI, intensifying competition and the need for efficiency” as the driving forces. He’s right. The regulatory environment is slowly warming up to AI in finance, and the race is on to see who can automate the most intelligently. I think we’re going to see a wave of consolidation in this space, with Zest AI potentially acquiring smaller players or facing off against other well-funded AI lending startups. The traditional boundaries of credit are being redrawn by algorithms, and Zest AI just got a lot more ink for its pen.
