Over 45% Cost Savings through Legacy Modernization for a Leading Online Bank

Challenges

Our client, a leading provider of wealth management solutions for business management firms, family offices, and high-net-worth individuals, needed to overcome the limitations of their decades-old legacy platform. Built over 40 years, the system was burdened with a multi-ledger, multi-bank setup that required extensive maintenance and slowed innovation.

The platform carried 600,000 lines of PL/1 code and 305,000 lines of legacy Windows framework code, processing over 900 million transactions annually. On top of that, the system supported more than 100 levels of complex approvals, payrolls, and unique scenarios, making modernization critical but highly complex. The client needed a clear assessment of the system, its data flows, and business processes to guide strategic modernization decisions.
