Fintech

What Is Fintech?

Fintech is the use of software, data, and modern infrastructure to deliver financial services such as payments, lending, and banking more cheaply and quickly than legacy institutions can. The term covers consumer apps, B2B fintech infrastructure, and embedded finance built into software products. Most fintech firms compete on speed, distribution, and data rather than balance sheet size.

How Fintech Works

Nearly every fintech product sits on a stack of four layers. At the bottom is a regulated entity: a chartered bank, a licensed money transmitter, or a card network member that holds the legal permission to move funds. Above it sits infrastructure, usually exposed as APIs for accounts, cards, ledgers, and payments. Above that sits the risk layer, where identity verification, underwriting models, and fraud scoring decide who gets approved and on what terms. At the top sits the interface the customer actually sees.

Banking as a service is the commercial arrangement that lets a company rent the bottom two layers instead of building them, which is how a software business can launch a card program in months rather than the years a charter application would take. Open banking rules, already mandatory in the UK and the EU and now spreading through US rulemaking, force banks to expose account data through permissioned APIs. That is what lets a lending technology provider read a borrower's actual cash flow instead of asking for PDF bank statements.

Fintech in Plain English

Banks used to own three things at once: the customer relationship, the ledger, and the credit decision. Fintech unbundled them. A neobank owns the customer and rents the ledger from a partner bank. A payments company moves the money but never holds the account. A specialty lender owns the credit decision and funds the loans through a warehouse facility. Each piece got faster because it got specialized, and software replaced the branch as the distribution channel.

The Major Fintech Categories

Payments is the largest revenue pool: card acquiring, issuing, wallets, and cross border transfers. Lending technology covers underwriting, servicing, and capital markets tooling for consumer and business credit. Neobank and deposit products compete on onboarding time and fee structure rather than on rate. Wealth and insurance technology apply the same automation to investing and policy underwriting. Regtech sells compliance as a product: sanctions screening, transaction monitoring, and regulatory reporting. Infrastructure companies sell the ledgers, processing, and bank connectivity that everyone else runs on.

How B2B Fintech and Embedded Finance Make Money

B2B fintech is where the economics have shifted most in the past five years. A vertical software platform that already owns the system of record for an industry can attach payments, lending, or insurance to workflows its customers run every day, and that attach is often worth more per account than the subscription itself.

Revenue arrives in four shapes: interchange on card volume, a take rate on processed payments, net interest margin or a spread on credit, and platform fees charged to the software vendor. Float on held balances matters when rates are high and largely disappears when they are not. The strategic case for embedded finance is retention as much as revenue. A customer who runs billing, collects payments, and finances receivables inside one product has a switching cost measured in quarters rather than weeks.

Fintech Regulation and Regtech

Because fintech touches money, credit, and sensitive personal data, the compliance surface is wide: money transmitter licensing state by state, sponsor bank oversight, KYC and AML programs, sanctions screening, PCI-DSS for card data, GDPR and similar privacy regimes, and consumer credit disclosure rules where they apply. Compliance is expensive to build and expensive to maintain, which is exactly why it functions as a moat. The firms that last treat it as core engineering rather than a legal afterthought.

Fintech and the Closing Motion

The Closing Motion is where fintech stops being abstract for a B2B software company. Propose, Close, Collect, and Renew are the four stages between a buyer's interest and money in the bank, and each has historically been handled by a different tool. Ratio applies fintech directly to that sequence. Ratio Trade underwrites the buyer during the proposal stage so the buyer can pay monthly or quarterly while the seller collects the full total contract value upfront, and Ratio Boost converts existing recurring contracts into upfront capital with no dilution and no warrants. This is embedded finance pointed at the close itself, not at product delivery, onboarding, or implementation. What it buys the seller is cash certainty at the moment of yes.

Common Questions About Fintech

Is fintech an industry or a business model?

Both labels get used, but the more useful answer is that fintech is a delivery method rather than a product category. The same deposit, payment, or credit product can be sold by a bank or by a software company. What makes it fintech is that software and data carry the process end to end.

Do fintech companies need a banking license?

Usually not directly. Most partner with a chartered bank or a licensed money transmitter that supplies the regulated permission, an arrangement commonly sold as banking as a service. Regulators increasingly hold both sides accountable, so the sponsor relationship carries real diligence, real reporting, and real cost.

How is B2B fintech different from consumer fintech?

Consumer fintech competes on acquisition cost and app experience across millions of small accounts. B2B fintech competes on integration depth, underwriting quality, and workflow fit, with far fewer customers at much larger values. B2B fintech typically needs less marketing spend to reach profitability but absorbs longer sales cycles.

Key Takeaways

• Fintech delivers payments, lending, and banking through software and data instead of branches and legacy core systems.
• The typical fintech stack has four layers: a regulated entity, infrastructure APIs, a risk and underwriting layer, and the customer interface.
• Banking as a service and open banking are what make embedded finance practical for companies that are not banks.
• B2B fintech monetizes through interchange, take rates, interest spread, and platform fees, and it deepens retention as much as revenue.
• Compliance work, from KYC and AML to PCI-DSS, is a permanent operating cost and one of the few durable moats in fintech.
