38% faster settlement times

Meridian Trust Bank

Meridian replaced a twenty-two-year-old mainframe batch job with a Halyard streaming pipeline. Overnight settlement dropped from 6.1 hours to 3.8. The seven-week migration ran alongside the legacy system with zero unplanned downtime and a full transaction-level parity check at cutover.
