Aggregator Routing Creates Product Moat
Monarch Money
Connection reliability is turning the account link itself into a product moat. In personal finance, the app wins or loses at the moment a bank feed breaks, because stale balances, missing transactions, and repeated reauthentication make the whole dashboard feel untrustworthy. A company that can route a Chase login through one provider, a Canadian bank through another, and switch the user to a better path when one feed degrades will keep more accounts live, collect cleaner data, and retain more paying households.

Routing matters because no aggregator is best everywhere. Monarch already uses Plaid, Finicity, and MX, and lets users switch providers when one connection is unreliable. That is not just wider coverage. It is a practical fallback system for keeping balances and transactions current across 13,000 plus institutions.

This advantage compounds with scale. The major aggregators have the strongest direct coverage only at the top few hundred banks, while the long tail is often outsourced or resold. Teams that run multiple providers also spend significant engineering time on retries, custom fixes, and multiplexing, so companies that build this routing layer well create a hard to copy reliability edge.

Open banking can improve this over time, but it does not erase the edge today. The CFPB finalized its personal financial data rights rule on October 22, 2024, then opened reconsideration in August 2025, and compliance dates were later stayed by a court in October 2025. That leaves routing quality and bank relationships as the near term determinant of sync quality.
The next phase of competition will be less about prettier budgeting screens and more about owning the financial data supply chain. As open banking standards roll out unevenly, the strongest consumer finance products will look more like traffic controllers behind the scenes, constantly choosing the cheapest and most reliable path to keep household data fresh enough that users never think about the plumbing.
