The Growth of Fintech Data Platforms

Fintech data platforms serve as the connective tissue of modern financial services. Plaid connects more than 12,000 financial institutions to applications like Venmo, Robinhood, and Coinbase, providing transaction data, account balances, identity verification, and income information through standardised APIs. MX Technologies provides similar connectivity with a focus on data enrichment, categorising raw transactions into meaningful spending categories.

The fintech data platform market exceeded $15 billion in 2024 and is projected to reach $40 billion by 2030, according to Allied Market Research. Open banking regulations are expanding the addressable market: the EU's PSD2, the UK's Open Banking framework, and Australia's Consumer Data Right require banks to share data through APIs. More than 10 million UK consumers used open banking services in 2024, and Brazil's framework enrolled over 25 million consumers after launching in 2021.

Plaid, valued at $13.4 billion, is the largest independent fintech data platform, with its APIs used by more than 8,000 fintech applications. Mastercard acquired Finicity for $825 million in 2020, gaining direct access to consumer financial data. Visa attempted to acquire Plaid for $5.3 billion, but the deal was blocked by the US Department of Justice on antitrust grounds — a measure of how strategically valuable data infrastructure has become.

Envestnet Yodlee provides data aggregation to more than 1,400 financial institutions. Akoya, created by major US banks including JPMorgan, Wells Fargo, and Bank of America, offers a bank-controlled data-sharing network as an alternative to screen-scraping. More than 30,000 fintech companies depend on data platform infrastructure to build and operate their products.

Fintech data platforms generate revenue through per-API-call pricing, monthly subscriptions, and data licensing. Plaid charges fintech applications per bank connection and per data request. Revenue scales directly with the growth of the fintech ecosystem — as more consumers link bank accounts to more applications, data platform revenue grows proportionally.

New use cases are expanding the market beyond basic account linking. Payroll connectivity allows fintech apps to verify income and employment in real time. Tax data platforms connect to IRS records for mortgage and lending verification. Investment data aggregation consolidates portfolio information across brokerages. Each new data category creates additional revenue streams and deepens the role data platforms play across financial services.
