Gerald Chappell spent years as a McKinsey partner watching banks turn away good borrowers because a credit score couldn't see what their bank statements could.
In 2020, he and Michelle He, formerly of EY, decided to stop watching and start building. Six years later, their company sits at the top of Britain's fastest-growing tech businesses. So how does Abound make money and why hasn't anyone managed to copy it yet?
What Is Abound?
Abound is a UK consumer lender that uses Open Banking and AI to assess borrowers by their real financial behaviour rather than their credit score. Founded in 2020 by Chappell and He, the company trades under Fintern Limited, is authorised and regulated by the Financial Conduct Authority under Firm Reference Number 929244, and is a member of Cifas, the UK's anti-fraud association which is usually the first thing anyone asks when they wonder is Abound loans legit before applying.
The numbers tell their own story. Abound has lent more than £1 billion since launch, a milestone it passed in under five years and served more than 150,000 customers as of 2025/26 along the way. On Trustpilot, it holds a score of 4.9 out of 5 from over 24,000 reviews, the kind of consistency that's rare in consumer lending.
Search for any Abound loans review online and the same theme keeps surfacing: borrowers describe the application as feeling less like an interrogation and more like an honest look at their finances. Before we get to how Abound makes money, it's worth understanding why that consistency exists in the first place. It comes down to what the company actually looks at when deciding who to lend to.
The Open Banking Risk Model Explained
Abound's Open Banking risk model works by reading a borrower's actual bank transactions in real time, rather than relying on a static credit score that can miss thin or misleading credit histories. Chappell has described this data as a "financial X-ray" , a phrase that captures exactly what the technology is built to do: see past the number and into the account itself.
Where a traditional lender asks how much debt you've carried and how reliably you've repaid it historically, Abound looks at income, spending patterns, and what's genuinely left over each month. It's a subtle but important shift from judging the past to reading the present.
This underwriting engine doesn't just power Abound's own lending. It's been packaged into a separate product called Render, an AI-powered credit decisioning platform that Abound licenses to other lenders across Europe, including clients such as GAIA Family and LemFi. Render turns the same real-time transaction analysis into a tool other companies can plug into their own lending decisions and understanding Render is essential to understanding how Abound makes money, because it's the second half of the business entirely.
How It Makes Money: Interest on Personal Loans
Abound makes money in two ways: interest earned on the personal loans it issues directly to consumers, and fees charged to other lenders who license its Render decisioning platform. The first is the familiar lending business; the second is the software business quietly running underneath it.
On the consumer side, Abound offers unsecured personal loans directly; it's a lender, not a broker with a representative APR of 21.8% on loans between £5,000 and £12,000, and no arrangement fee, so the APR and the interest rate are effectively one and the same. That's the core mechanic behind how Abound makes money on its consumer book: interest, priced individually per borrower based on what Open Banking data says they can actually afford, rather than a blanket rate set by a blunt credit tier.
The Render side is smaller but strategically important. Every time a partner lender uses Render to assess a borrower, Abound earns a fee turning its underwriting technology into a second revenue line that doesn't depend on Abound holding the loan itself. Two engines, one dataset, one answer to how Abound makes money at scale.
Why Big Banks Haven't Replicated It
Big banks haven't replicated Abound's model because rebuilding decades-old credit infrastructure around real-time Open Banking data is a multi-year overhaul, not a feature update. Asked directly why an established bank couldn't simply build the same thing, Chappell told TechCrunch: "This is very non-trivial. It would take banks five years or more to change their processes."
That's not a throwaway line, it's the whole moat. A high street bank's credit decisioning is wired into legacy systems, risk committees, and regulatory sign-off processes built for a world before Open Banking existed. Abound built its stack from scratch, with nothing legacy to unwind which is a large part of why how Abound makes money looks so different from how a traditional bank does.
The profitability timeline backs this up. Abound turned a profit after just three years Chappell has called this "unusually early for a UK fintech" at a moment when, in co-founder Michelle He's words, "the era of rapidly growing tech firms without a clear path to profit is ending." For founders watching from the sidelines, that's the real lesson: Abound didn't just build better technology. It built a business model that reached profitability while most fintech peers were still burning cash chasing growth.
Growth and Recognition: Sunday Times Tech 100
Abound topped the 2026 Sunday Times 100 Tech ranking Britain's league table of fastest-growing private technology companies recording 490% annual growth over three years and £66.8 million in revenue, up from £26.6 million the year before. Net profit surged to £7.5 million, a 25-fold jump from £300,000 twelve months earlier. The company now employs around 120 people from a single office in Bermondsey, London, a genuinely small footprint for a business generating that kind of growth. It's the kind of scale that turns up in every subsequent Abound loans review, usually as evidence the company isn't a fly-by-night lender.
The recognition hasn't come with the company standing still. In January 2026, Abound made its first-ever acquisition, buying Ahauz, a specialist lender in shared equity mortgages founded by João Rocha and Karthik Srivats. The deal moved Abound beyond personal loans and into UK mortgages for the first time, with its debut homeowner product, the Rezide Equity Loan, launched alongside housebuilders Barratt, Redrow, and Persimmon. It offers a loan worth 15% of a property's value at 4% interest, repaid alongside the main mortgage pitch, in effect, as a private successor to the old Help to Buy scheme.
It's a quiet but telling move. A lender that made its name proving Open Banking data could underwrite better personal loans is now betting the same logic works on much bigger numbers.
FAQs
1. Is Abound loans legit?
Yes Abound is a UK lender authorised and regulated by the Financial Conduct Authority under Firm Reference Number 929244, operated by Fintern Limited (Company No. 12472034). It's also a member of Cifas and registered with the ICO under UK data protection rules, meaning it's held to the same responsible-lending standards as any regulated consumer lender. Anyone reading an Abound loans review before applying will typically find this regulatory status referenced as a baseline reassurance.
2. What is Open Banking lending?
Open Banking lending means a lender assesses a borrower using their real, consented bank transaction data rather than relying solely on a credit score. The framework has existed in the UK since 2018, following the introduction of Open Banking regulation and the EU's revised Payment Services Directive (PSD2), which require banks to share financial data securely with authorised third parties.
3. How is Abound different from traditional lenders?
Abound reads real-time bank transaction data to judge affordability, while traditional lenders lean heavily on historical credit scores that can miss thin or unusual credit files. That difference is precisely why Abound says it can lend to people traditional banks routinely turn away, without taking on disproportionate risk.
The Bottom Line
So, how does Abound make money? Through interest on personal loans it underwrites using real Open Banking data, and through licensing fees from Render, the decisioning platform it sells to other lenders. It's a model built on reading borrowers accurately rather than judging them by a score and it's working well enough that Abound is now the fastest-growing tech company in Britain, with a fresh bet on mortgages to prove the model scales beyond personal loans.
