Keep the spreadsheet, the green-screen ERP, and the bespoke tool that still does its job, and connect them to a modern AI workflow without rewriting any of them.
Legacy system integration connects old systems, a decade-old ERP, an owner’s Excel workbook, a bespoke in-house tool, to modern AI workflows without rewriting them. A bridge reads and writes through each system’s existing surface, so the old systems keep doing their job while finally participating in modern automation, with no multi-year migration.
We sit with your business. We find the operational problem costing you the most. We build the system that fixes it.
Half the business runs on a 2008 ERP that nobody dares migrate. The other half lives in an Excel workbook one person owns. The bespoke tool from a decade ago still does its one job better than anything off-the-shelf. Replacing them is a multi-year project nobody can stomach, but leaving them disconnected means every modern AI workflow stops at their walls.
A bridge that reads and writes through each legacy system's existing surface area, a file watcher on the Excel workbook, an ODBC read against the ERP database, an API wrapper around the bespoke tool. Changes flow into a normalised event stream, an AI agent enriches them, the result lands in a cloud database and the relevant modern SaaS, and the bridge writes the answer back to the legacy system through the same surface it read from.
Nobody had to migrate anything. The old systems kept doing their job. The bridge made them participate in modern AI workflows for the first time, new pipeline rows got win-probability and next-best-action in Excel, ERP orders cleared credit before posting, bespoke records got AI follow-up notes, all without touching a line of legacy code.
One example of how we'd wire this capability. We'd shape it to your business.
The bridge listens on the legacy system's existing surface, normalises the change, sends it to a modern stack for enrichment, and writes the result back, through the same surface. No migration project.

Explore AutomationEvery legacy event becomes a recorded message with its origin surface, the rule that handled it, the AI output, and the write-back confirmation, so even un-modernised systems acquire a clean audit trail.
