Financial data connectivity providers don't ship financial products themselves—they ship the pipes the other 15 categories run on. The category sits at the intersection of two data domains: Open Banking (consumer and business bank data, regulated via PSD2/PSD3, UK CMA9, US CFPB-1033, and FDX-aligned standards) and Open Accounting (accounting and ERP system data, exposed through unified APIs). Plaid built a $13B+ business on bank-to-app connectivity; Codat and Finicity were acquired by Visa and Mastercard for the same reason. This is the foundational layer of embedded finance: bank-account linking on the Open Banking side (Plaid, TrueLayer, Tink, Yapily, Finicity, MX, Yodlee, GoCardless Bank Account Data) and accounting/ERP connectivity on the Open Accounting side (Codat, Apideck), plus commerce data (Rutter), HRIS/ATS unified APIs (Merge), and employment data (Finch, Pinwheel). If you're building lending, embedded payments, account aggregation, or any product that needs a customer's bank or accounting data, you start here.

Frequently Asked Questions
What is financial data connectivity?
Financial data connectivity providers offer APIs that link a customer's financial data sources—bank accounts, accounting software, payroll systems, e-commerce platforms—into another application. Plaid pioneered the model for consumer bank accounts in the US. TrueLayer, Tink, Yapily, and GoCardless Bank Account Data run the equivalent in Europe under PSD2 / PSD3. Codat and Apideck extend the same idea to accounting, commerce, and HRIS data. They're foundational infrastructure: lenders use them to underwrite, BaaS platforms use them to verify accounts, expense tools use them to import transactions.
Why is financial data connectivity treated as a foundational category here, not a product category?
The other 15 categories on this directory are products non-banks ship to end customers (BaaS accounts, issued cards, payroll runs, lending products). Financial data connectivity is sold business-to-business—to the people building those products. It sits underneath the product layer. Treating it as a peer would be confusing; treating it as foundational is editorially honest. The market validated the category independently: Plaid peaked at a $13B+ valuation, Tink was acquired by Visa for $2.1B, Finicity by Mastercard for $825M, Codat by Visa, Nordigen by GoCardless. Pure connectivity plays attracting major strategic acquirers.
Plaid vs TrueLayer vs Tink vs Yapily — which should I use?
Geography is the first filter. Plaid is strongest in the US and Canada with broad coverage (also live in 18 European countries). TrueLayer, Tink, and Yapily are PSD2-native in the UK and EU. For Europe-only, TrueLayer leads in payments-via-open-banking, Tink (now Visa) has the broadest data coverage, Yapily is API-first with no consumer-facing UI. Klarna Kosma is Klarna's own open banking arm. GoCardless Bank Account Data (formerly Nordigen) is free for AIS use cases. For US bank-account linking specifically, Plaid is the de facto standard, with MX, Yodlee, Finicity, Atomic, and Method as alternatives—each with different strengths in employment data (Pinwheel, Atomic), liability data (Method), or wealth data (Yodlee).
Plaid does bank data — what about accounting, payroll, or commerce data?
Bank-account connectivity is one slice. Accounting and ERP connectivity is the parallel category, dominated by Codat (acquired by Visa) and Apideck. HRIS and ATS connectivity is owned by Merge. Employment and payroll data is Finch and Pinwheel. Commerce-platform data (Shopify, Amazon, BigCommerce) is Rutter. The Plaid/Apideck thesis is the same in each: businesses need their financial data to flow between systems, and building those connections in-house doesn't scale. Whichever data domain you need, there's a unified-API layer for it.
How does this category relate to Open Banking and Open Accounting on the site?
This category is effectively the union of two parallel data layers we cover separately on the rest of the site. Open Banking covers bank-account data and payment initiation under regulatory regimes like PSD2/PSD3 (EU), CMA9 (UK), CFPB-1033 (US), and FDX-aligned standards globally—see the dedicated Open Banking guide, the API aggregators directory, and the Third-Party Provider directory. Open Accounting covers accounting and ERP system data via unified APIs from providers like Codat and Apideck—see the dedicated Open Accounting page. Financial data connectivity is the embedded-finance lens on both: it includes open-banking-based providers, pre-PSD2 screen-scrapers like Yodlee, accounting and ERP connectivity, HRIS/ATS unified APIs, and employment data—anything that pipes a customer's financial data into another product.
