Wintrust $15B Custodian Conversion | Data Readiness in Wealth Management

▤ Summary

Wintrust moved roughly $15 billion in brokerage and advisory assets to a new custodian and reduced conversion risk by relying on a long-established, independent data foundation. Terrapin Technologies had aggregated and standardized Wintrust's operational data for nearly two decades, which allowed reporting, advisor compensation, and Workday integrations to continue without disruption during a mid-cycle cutover. That independent, mapped, and validated data layer minimized dependence on the new custodian's file formats and preserved operational flexibility. The case underlines that treating data as a managed strategic asset — and preparing it long before a conversion — materially lowers operational and reporting risks.
