Bought or built, all you have is a demo. Nobody hands you an audit. Building one costs months of engineering, then upkeep forever. Holdout rebuilds your system from logs you already have and checks every record the agent touches.
It re-runs nightly, so a model update cannot quietly cost you a double-paid invoice or a merged customer.
Figures from the Holdout benchmark suite — benchmark.holdout.systems
A working copy of your system, built from the logs and exports your systems already produce. Nothing new to install, no production access. Proven faithful by replaying real traffic the copy has never seen.
The agent works a queue of real records: real tickets, real invoices, real CRM messes. Afterwards every record it touched is checked. Fixed, missed, or made worse, with damage subtracted.
Bring one agent and one queue you are worried about. Thirty minutes, and you leave knowing whether your logs are enough to build a working copy.
