Open Banking Commoditizes Data Access

Open banking shifts financial data access from a proprietary moat into a thin transport layer, which pushes the real profit pool toward whoever can turn messy account feeds into decisions and workflows. Once multiple aggregators are pulling from the same bank APIs, raw coverage and basic connectivity matter less. What matters more is cleaning transaction strings, identifying subscriptions, estimating income, scoring risk, and packaging that into products fintechs can buy off the shelf.

• Plaid originally won on developer experience and easier pricing, not uniquely better raw data. As bank connections standardize, that early edge gets harder to defend with access alone, so aggregation vendors move upward into enrichment, identity, income, and payments.

• For a personal finance app, raw transaction rows are not the product. The product is a readable feed with merchant names, logos, recurring bills, and alerts. For a lender, the product is not bank access either, it is an underwriting signal built from cash flow patterns.

• This is also why multiplexer layers like Venice exist. If the underlying connectors are increasingly interchangeable, fintechs want optionality across Plaid, Yodlee, MX, and direct bank APIs, while keeping one internal integration and avoiding vendor lock in.

The next phase of the market is a split between low margin connectivity and higher margin application logic built on top of it. The winners will be the companies that own the last mile from bank data to outcome, whether that outcome is approved loan, switched paycheck, detected subscription, or cheaper account to account payment.
