Financial technology — fintech — is the application of software to financial services. It encompasses digital banks that never touch a branch, lending platforms that use machine learning to underwrite credit, investment apps that democratise access to stocks and ETFs, and crypto exchanges that enable borderless value transfer.
The global fintech market generated over $200 billion in revenue in 2024 and continues to grow at 15–20% annually, despite a significant valuation correction in 2022–2023 that culled many undercapitalised players. What remains is a more mature cohort of companies with real revenue, improving unit economics, and defensible market positions.
What Makes Fintech Different From Traditional Finance
Traditional financial institutions are burdened by legacy core banking systems, physical branch infrastructure, and compliance overhead built over decades. Fintech companies start with modern technology stacks, no legacy infrastructure, and digital-native customer acquisition — giving them structural cost advantages in customer onboarding, underwriting, and service delivery.
The critical difference is the absence of a banking licence for most fintechs — which means they must partner with licensed banks to hold customer deposits, extend credit, or operate payment accounts. This bank-partnership model is the primary regulatory and operational complexity for most consumer fintech companies.
Fintech Business Models
Digital Lending
Fintech lenders use alternative data (bank account cash flows, purchase history, education) to underwrite loans faster and more cheaply than banks. Revenue is net interest income (interest charged minus cost of funds) plus origination fees. Affirm, Upstart, and Rocket Companies compete here.
The key risk: credit losses during economic downturns. Fintech lenders that grew rapidly in the 2020–2021 low-rate environment faced severe delinquency increases in 2022–2024 as rates rose and consumer finances tightened.
Neo-Banking / Digital Banking
Neobanks offer checking accounts, debit cards, and basic financial services through a mobile app with no physical branches. Revenue comes primarily from interchange fees (a cut of every debit card transaction), premium account subscriptions, and financial product cross-sales (investing, lending).
SoFi has evolved beyond neobanking into a full-service digital financial services company with a banking licence, offering loans, investments, insurance, and a credit card. Nu Holdings (Nubank) is the world’s largest neobank by customers, with over 100 million accounts across Latin America.
Retail Investing and Brokerage
Commission-free investing apps democratised stock market access. The revenue model shifted from commissions to payment for order flow (PFOF) — selling customer order flow to market makers who execute trades. Robinhood pioneered this model in the US; Coinbase applies similar logic to crypto.
Tax and Financial Management Software
Intuit (TurboTax, QuickBooks, Credit Karma) serves both consumer and small business financial management. This is more traditional SaaS than disruptive fintech — but the platform flywheel (tax data → credit data → banking → lending) creates significant cross-sell leverage.
Alternative Lending and BNPL
Buy Now Pay Later and instalment lending extend credit at point of sale without requiring a credit card. Affirm focuses on large-ticket items (furniture, electronics, travel) and charges merchants rather than consumers for the financing option. Upstart uses AI-driven underwriting to serve borrowers that traditional FICO scoring would decline.

Key Metrics for Fintech Companies
Revenue Growth Rate
Fintech companies should be growing revenue 20%+ in their high-growth phase. Slowing growth below 15% at scale signals market saturation or competitive pressure.
Gross Margin
Fintech gross margins vary enormously by business model. Software-driven fintechs (Intuit, Robinhood’s subscription products) run 80%+ gross margins. Lending businesses carry lower gross margins because loan origination costs and credit loss provisions are COGS-like. Target: 50%+ for scaled fintech; 70%+ for software-first platforms.
Net Interest Margin (NIM)
For fintech lenders and neobanks, NIM measures the spread between what they earn on loans/deposits and what they pay for their cost of funds. NIM compression during high-rate environments or rising credit losses are the primary earnings risk.
Credit Loss Rates / Delinquency
For lending-focused fintechs, net charge-off rates (loans written off as uncollectable) and 30/60/90-day delinquency rates are the primary risk metrics. Rising delinquencies foreshadow future credit losses and NIM compression.
Monthly Active Users (MAU) and Engagement
For consumer fintech platforms (Robinhood, Cash App, Nubank), MAU growth and transactions per active user measure platform engagement. Higher engagement drives more interchange revenue, cross-sell opportunities, and switching costs.
Deferred Revenue and ARR
For software-first fintechs like Intuit, ARR and net customer retention mirror enterprise SaaS metrics. QuickBooks’ accountant partner channel drives high NRR.
The Regulatory Risk Factor
Fintech companies face asymmetric regulatory risk compared to incumbents. Key exposures:
- CFPB oversight: Consumer Financial Protection Bureau enforcement actions on lending practices, fee disclosures, and data privacy
- Crypto regulation: SEC vs CFTC jurisdiction battles create compliance uncertainty for Coinbase and Robinhood’s crypto products
- Bank partnership dependencies: Fintechs operating without their own banking licence depend on chartered bank partners — regulatory action against the partner bank can cripple the fintech
- PFOF restrictions: European regulators have banned payment for order flow; US restrictions could reshape Robinhood’s core business model
