Synapse Collapse Spurs Bank Integration
Column
Synapse’s collapse showed that the weak point in middleware BaaS is not just margins, it is operational control over money movement and records. In this model, the fintech, middleware provider, and sponsor bank each see only part of the system, so when something breaks, reconciliation, support, and accountability can fracture across multiple parties. That matters because the product is not just APIs, it is the trusted chain that keeps customer balances, compliance decisions, and bank permissions aligned every day.

Middleware providers sit between the fintech and the bank, which helps a startup launch fast, but also creates built in tension. The provider wants growth and volume, while the bank carries the regulatory burden and may tighten controls, slowing approvals and creating friction around KYC, fraud, and account monitoring.

The economics are also thinner than they look. Middleware has to share revenue with sponsor banks and often other infrastructure vendors, while charging fintechs monthly minimums and usage fees. That works for early launches, but larger fintechs often leave the middle layer once volume grows and customization becomes worth building directly.

The market response after Synapse has favored models with fewer handoffs. Mercury added Column as a partner bank in October 2024, and Column has positioned its own charter, ledger, payments access, and compliance stack as a way to replace the usual multi vendor setup with one operating system for deposits, payments, and issuing.
The category is moving toward tighter bank integration, whether through tech forward banks like Column or middleware platforms that give banks much deeper visibility into the same ledger and cases fintechs see. The winners are likely to be the providers that make the bank and the fintech operate from one shared system, not two or three stitched together ones.
