Definition
Account Aggregator (AA) is an RBI-regulated entity that facilitates user-consented financial data sharing across financial institutions. AAs sit between financial information providers (banks, mutual funds, insurance) and financial information users (fintech apps, lenders).
The AA framework enables real-time, user-consented access to a user's complete financial data — bank statements, investments, GST returns, etc. — to be used for credit decisioning, financial planning, or compliance.
India Context
Registered Indian Account Aggregators in 2026 include Setu (acquired by Pine Labs), Anumati, Onemoney, Finvu, and several others. The AA ecosystem has reached scale — over 50M consents per month.
Fintech startups building on AA infrastructure are universally treated as more diligenced by Indian VCs because they're operating within the regulated framework rather than scraping or accessing data via less regulated routes.
Example
A wealth management app integrates with an AA to fetch a user's complete portfolio across multiple banks and mutual funds in real-time, with user consent. Without AA, this would require manual statement uploads or PDF parsing — both error-prone. AA enables 100% structured, real-time data flow.
