Data Aggregator Market Analysis

A financial data aggregator connects to a consumer’s bank accounts and normalizes that data into a single feed a fintech product can build on. Nearly every modern financial product touches one somewhere in its stack: personal finance and budgeting apps, account-to-account transfer tools, credit decisioning engines, wealth management platforms, and the open banking layer that lets a consumer link accounts to outside apps in the first place. If you’ve ever connected a bank account to a financial app, you’ve used a data aggregator, most likely without knowing its name. This report gives you a grounded view of how aggregators work, who the leading providers are, and where the market is headed.

How data aggregation works, and why the rules are changing

For years, aggregators pulled data by logging into a bank’s website on a consumer’s behalf and scraping the page, a fragile approach prone to outages and security gaps. The industry has been shifting toward secure, API-based connections instead, a shift accelerated by Section 1033 of the Dodd-Frank Act, which requires banks to make a consumer’s financial data available to a data aggregator at that consumer’s request. The rule also sets new standards for third-party access, pushing the market away from screen scraping and toward the kind of compliance, security, and data-retention transparency Totavi advises on through our compliance, risk, and operations work.

The leading data aggregators

This report profiles five of the market’s core providers. Plaid is the most widely recognized name, connecting to more than 12,000 financial institutions and known for developer-first documentation. Finicity, acquired by Mastercard in 2020, has built a following among smaller financial institutions and account-to-account payment use cases. MX has the broadest reach of the group, with over 16,000 institution connections rooted in its origins serving community banks. Teller is the smallest by headcount and coverage but has attracted high-profile fintech partners with a fast, focused API. Yodlee, founded in 1999, is the industry’s elder statesman, with the deepest legacy footprint among large enterprises and public companies. Beyond the core five, the landscape includes bank-led alternatives like Akoya and “super aggregators” that layer on top of the core providers, such as Stripe, which now connects to more than 97% of US bank accounts as part of a broader payments platform, the kind of card and payments infrastructure Totavi also covers in its Credit Card Program Management Platform Market Analysis.

What the data shows

Demand for a unified financial view keeps climbing. 71% of consumers now hold more than one credit card, and 72% say they would switch banks if their institution didn’t support linking accounts to outside apps. In Totavi’s August 2024 survey of 67 fintech decision-makers, reliability ranked as the most important factor in choosing an aggregator (27%), ahead of security (21%) and speed and developer experience (tied at 15% each). Consumer awareness, meanwhile, lags well behind adoption. A Clearing House survey found 80% of consumers didn’t realize their apps were collecting data through a third-party aggregator, 78% didn’t know that data collection continues until they revoke access, and only 23% read the terms and conditions that disclose it.

Where the data aggregation market is headed

Plaid remains the dominant name in the space, but the market is far from settled. Totavi’s research surfaced recurring complaints about outages, coverage gaps, and customer support, room for disruption that a new or existing provider willing to solve those specific pain points could capture. Section 1033 will keep pushing the industry toward standardized, API-based access and away from fragile screen scraping, and coverage will keep expanding as long as any financial institution remains unconnected. For product teams building on top of an aggregator, that shifting landscape makes vendor selection as much a build decision as a partnership one.
