Embedded finance =
Every app is becoming a bank.
Toast moves payments. Shopify writes loans. Lyft issues cards. Brex runs treasury. Airbnb sells flexibility. All of it powered by invisible banks behind a handful of APIs — except Mews, which skipped the bank: in 2026 it became the first hospitality-vertical SaaS platform to hold its own e-money licence, granted by De Nederlandsche Bank. Once a consumer-neobank story (Chime, Revolut, N26), embedded finance is now the default playbook for vertical SaaS, marketplaces, B2B platforms, and even non-financial brands — anyone who can ship a payment, issue a card, write a loan, or hold a balance without sending users to a third party. The 18-month bank-charter project is now a two-week API integration.

Which layers are auditable. Which go dark.
For each layer of the embedded-finance stack: what share of 542 analyzed fintechs publicly named a vendor? The gap between the green and red rows is the dark half of the stack — the layers regulators, integrity researchers, and journalists can’t audit from outside.

What this meansThe payments side of the stack is auditable from outside. The risk side isn’t. Public datasets of vendor relationships — including this one — will always over-represent payments and under-represent KYC, fraud, and sanctions screening. Treat the red rows as a floor, not a ceiling. The “% masked” column is the second-order finding: even when a layer IS disclosed, a meaningful fraction of companies talk about their own-brand product (“Acme Pay”, “Acme Checkout”) without identifying the underlying provider. ~34% of fintechs that mention a PSP, and ~37% of fintechs that mention BaaS, hide the actual infrastructure behind a brand wrapper — a structural masking effect that makes the auditable-looking layers thinner than they appear.
“Open banking opened the access door to financial data, but access and usability are not the same thing. A full internal transaction record carries around nine usable data points. What comes through an open banking API is typically two, sometimes four.”

Section 03 · dataset composition
What kind of fintech are these?
The 542 fintechs in this dataset split into 9 working categories. Infrastructure providers (BaaS, card issuing, PSP) sit alongside the platforms that consume them (vertical SaaS, marketplaces, B2B fintech) — the report is a snapshot of an ecosystem where buyer and seller often appear in the same chart. 834 entries were excluded as non-fintech (investor/advisory firms, non-financial orgs, press fragments) before this breakdown.

“Requirements such as independent reconciliation, per-partner FBO accounts and treasury-grade audit trails are becoming standard — capabilities that are significantly faster to access through established partners.”

“Payments may be the entry point, but lending is becoming the real revenue engine for vertical SaaS platforms because they own operational data traditional lenders do not have access to.”

“Linking a third-party bank account inside a primary banking app is now seen by customers as a baseline feature rather than a nice-to-have, and institutions that do not offer it stand out for the wrong reasons.”
