"A huge portion of America and a huge portion of people around the world are essentially by design cut out of the formal financial system."
"People know they should be doing it, but they just don't necessarily have the solutions in place right now to be doing it."
Cash flow underwriting, explainable AI, and credit risk analytics are reshaping how lenders approve borrowers and price loans. Tedd Huff, CEO of fintech advisory firm Voalyre and founder of Fintech Confidential, sits down in Las Vegas with Jamie Twiss, CEO of Carrington Labs, and Kasey Kaplan, Carrington Labs' Chief Product and Commercial Officer, to break down how machine learning models trained on bank transaction data are outperforming traditional credit scores. Jamie spent years building credit risk models inside banks before serving as Chief Data Officer at a global top 50 institution. Kasey built his career across payments, program management, and lending. Together they launched Carrington Labs out of the mission-driven lender Beforepay to tackle the blind spots that credit bureaus have ignored for decades.
The core tension is straightforward. Tedd pointed to a LexisNexis report showing that over 50 percent of loan applicants cannot produce a reliable credit score, and he pressed on who gets hurt the most: self-employed workers, gig earners, younger borrowers who avoid credit cards, and anyone new to a country. These groups get filtered out by a system that only measures past engagement with credit products. Lenders lose business. Borrowers lose access. The economy loses capital deployment that could be productive.
Carrington Labs trains its models on billions of lines of bank transaction data, pulling behavioral signals that standard bureau scores miss entirely. The examples are specific: when a cash crunch approaches, does a borrower cut discretionary spending 21 days out, seven days out, or three? When an obligation hits, do they move money around to meet it, or let a direct debit bounce against an empty account? Do they shift from Safeway to Costco when balances drop? These behavioral patterns are, according to Jamie, enormously predictive of willingness and ability to repay.
The natural pushback from compliance teams and risk officers is that AI in lending means black box decisions that regulators will reject. Tedd framed the concern directly:
"They can't afford AI tools to be a black box. They can't do it for compliance. They can't do it for payments, they can't do it for lending."

Carrington addresses this head-on by splitting their workflow at what they call a "control point." Upstream of that control point, AI and generative models do heavy lifting during feature generation and model creation. A human reviews every feature and signs off before anything goes into production. Downstream of the control point, everything is deterministic: same input, same output, fully explainable. Kasey shared a telling example; some lenders they've encountered were literally calling the OpenAI API with borrower data and asking ChatGPT whether to approve a loan, then getting different answers at different times. Carrington's architecture avoids that by keeping final decisions within reproducible, auditable machine learning models.
For lenders dealing with high decline rates and rising acquisition costs, the commercial case goes beyond approval percentages. Carrington builds personalized models per lender, per product, and per customer segment, using that lender's own data. A wage advance carries a different risk profile than SMB lending or auto leasing, and the same borrower can look very different across those products. Off-the-shelf models are available for lenders with no existing data, and the system shifts to custom models as performance signals come in. Kasey compared the approach to e-commerce personalization: instead of generalized risk bands, lenders get probability of default percentages for each individual borrower, which maps directly to unit economics and lifetime value.
Tedd also pushed the conversation toward a shift most lenders have not made yet: moving from point-in-time underwriting at origination to ongoing, recursive underwriting throughout the life of a loan. He raised a scenario where rising fuel costs, with gas in Las Vegas ranging from $5.29 to $6.29 a gallon at the time of recording, start compressing discretionary income in ways that a one-time credit check would never catch. Carrington's cashflow servicing capability can detect that kind of early distress, flag when spending patterns change, and help lenders adjust credit limits on products like credit cards. Jamie described a scenario where a lender with 100,000 credit card holders could identify 5,000 showing emerging stress and 30,000 performing well enough to support meaningful limit increases.

Open banking access remains a pressure point, especially in the US where institutions like JP Morgan have moved to charge for data access. Jamie argued that restricting customer data sharing signals a lack of confidence and pushes consumers toward less secure methods like emailing bank statements. Tedd connected that to a broader pattern he has seen across fintech, noting that email has become a workaround when API-based data access gets blocked, essentially a regression to less secure channels. Kasey added nuance about compliance costs for smaller institutions and differences in regulatory frameworks between the US and Australia, where restrictions on derived data are tighter.
Looking ahead five years, Jamie predicted credit will become embedded in financial life, with AI agents seeking and deploying capital on behalf of borrowers while lenders use far richer data sets for more precise decisions. Kasey expects regulation to catch up, friction to drop across applications and access to capital, and consolidation among smaller institutions that cannot fund the shift. Both signaled that non-financial companies closest to customers, like retailers, may eventually step into lending if the decisioning, origination, and servicing tools become accessible enough.
Tedd closed the conversation by distilling three takeaways that cut across the full discussion: lending is not a simple yes or no decision, siloed data can still produce strong outcomes without consortium sharing, and the industry is still in the early innings of what this technology can do. For treasury managers, CFOs, and compliance leaders evaluating AI tools for lending, this conversation lays out the operational line between generative AI and explainable machine learning, the commercial math behind personalized scoring, and the practical steps to move from bureau-dependent underwriting to cashflow-based decisioning. The specifics on behavioral features, model retraining, and lifecycle monitoring make the case that this is an operational shift already producing measurable results for lenders globally.
TLDR:
Credit scores have barely changed since the late 1980s, and over half of loan applicants still cannot get a reliable one. Tedd Huff, CEO of fintech advisory firm Voalyre and founder of Fintech Confidential, sits down with Jamie Twiss, CEO of Carrington Labs, and Kasey Kaplan, Chief Product and Commercial Officer, to unpack how cash flow underwriting using bank transaction data is giving lenders a sharper, fairer way to assess borrowers. They break down why behavioral signals buried in everyday spending habits predict repayment better than bureau scores, how to use AI upstream while keeping lending decisions fully explainable, and where the real margin gains hide across origination, limit sizing, and post-origination servicing. Jamie and Kasey also share where they see AI-powered lending heading over the next five years, including the rise of embedded credit and agent-driven borrowing. If you make, manage, or evaluate lending decisions, this one is worth your time.

Key Highlights:
Millennials Are Rejecting Credit Cards
Younger borrowers watched their parents drown in debt, and now they avoid credit products even when they can afford them. Traditional scoring systems penalize that restraint, leaving responsible earners with weak credit files and fewer lending options.
Lending His Own Net Worth Daily
Carrington Labs proves confidence in its models by running a large portion of its own capital through the same decisioning system clients use. That alignment, lending significantly more than the CEO's personal net worth every single day, gives partner lenders a level of assurance most vendors cannot match.
AI Agents Will Apply For Loans
Within five years, AI agents are expected to seek, compare, and deploy credit on behalf of consumers without a single traditional application form. The shift from manual applications to embedded, agent-driven borrowing could make today's origination process feel as outdated as a fax machine.
Thousands Of Useless Model Features
Some lenders brag about having thousands of features in their credit models, but many are just the same metric repeated across different time windows. Grocery spend at seven days, 14 days, 30 days, and 60 days adds volume without adding predictive quality, and that brute force approach loses to a handful of well-designed behavioral features.
Fault Tolerant Versus Fault Intolerant AI
A quality issue in AI-generated marketing copy is forgivable; a quality issue in a lending decision is not. Financial leaders need to classify every AI use case by its tolerance for error before selecting the architecture behind it.
Informal Loans Between Friends Exposed
Bank transaction data can reveal whether a borrower received money from a cousin, whether that transfer was a loan or a gift, and whether it was repaid before or after the next paycheck arrived. That granularity of behavioral insight sits in the data most lenders already have access to but never examine.
Car Retailers May Become Lenders
Non-financial businesses sitting closest to the customer and the transaction data stream are evaluating whether they should originate credit themselves. If decisioning, limit setting, and servicing tools become accessible to smaller operators, lending could spread well beyond banks and fintechs.
$20 Billion AI Lending Market By 2037
AI-powered loan origination is projected to hit $20 billion within the next decade, and most of that growth will come from lenders replacing point-in-time bureau pulls with ongoing, data-rich decisioning. The lenders who wait for the market to mature risk losing both margin and market share to those already building the infrastructure.
MCP Server For Credit Decisions
Carrington Labs built an MCP server that allows credit teams and support staff to query model results for a specific borrower without reading through hundreds of lines of schema. That same server supports agentic workflows, giving AI-powered systems access to contextualized risk scores and limit rationale in real time.
Stop Separating Approvals From Loan Terms
Most lenders treat the approval decision and the terms of the loan, limit, duration, and pricing, as separate processes handled by separate teams. Connecting those two workflows into a single optimized decision is, according to the advice given, the single highest-impact change a lending operation can make right now.

Takeaways:
1️⃣Instrument Every Step Of Your Funnel
Lenders pour money into acquisition and then have no idea where borrowers drop out or why. Map analytics to every single step from account creation to loan acceptance, pair quantitative data with qualitative research at each stage, and you will find the exact friction points bleeding your conversion rate. Pricing too high? Bureau pull anxiety? Open banking consent hesitation? You cannot fix what you are not measuring.
2️⃣Buy Best Of Breed, Stop Building
If your core strength is the customer relationship, spending two years and a seven-figure budget building proprietary underwriting tech is the wrong move. Best-of-breed origination, decisioning, and servicing tools already exist and can be assembled faster than any internal team can ship. Redirect that engineering budget toward understanding customer pain points and differentiating the product, because that is where lenders actually win or lose.
3️⃣Start Lending Small, Then Retrain Fast
You do not need a massive data set on day one to deploy machine learning models for credit risk. Put a small number of loans out using off-the-shelf models, collect performance signal, and rapidly shift to custom models trained on your own portfolio data. The conservative ramp-up approach gets you to precision faster than dumping capital out the door and hoping the data catches up.
4️⃣Offer Higher Limits For More Data
Borrowers who get approved for a smaller amount using traditional methods often want more but do not know how to get it. Give them a clear path: sync additional bank accounts through open banking, allow cashflow underwriting to assess their full serviceability, and reward that transparency with higher limits. You increase average balances, the borrower gets better terms, and your model gets richer data to sharpen future decisions.
5️⃣Watch How Borrowers Respond To Scarcity
A credit score tells you what someone did with past loans. Transaction data tells you what they do when money gets tight. Track whether borrowers trade down to cheaper providers when their balance runs low, whether they adjust spending weeks before a crunch or days before, and whether they prioritize obligations over discretionary purchases. Build those behavioral responses into your underwriting criteria and you will catch risk signals that bureau scores completely miss.
