Jack Henry serves banks and financial institutions with core banking, payment processing and digital banking. Like every system in your stack it holds a slice of the firm — account records, customer data, transaction histories and payment flows — under its own export limits, retention rules and terms governing what you may do with your own information. Milemarker connects to Jack Henry via a structured file feed. We start by reviewing what your Jack Henry agreement permits you to extract, store and reuse, then land account, customer and transaction data into a Snowflake environment your firm owns and administers, normalized into a model that stays stable even when the systems around it change. From there Jack Henry data is no longer isolated. It joins your RIA feeds, custodial data and other systems under one set of rules — row-level entitlements, PII masking and SOC 2 Type II controls you set — accelerating insight, improving communication and streamlining data management across all retail customers and affiliated members of your team.
