Data quality & curation
Data you don’t have to second‑guess.
We clean, reconcile and denoise your data, from spreadsheets to scanned contracts to call recordings. AI agents do the work; people review and approve the changes.
Talk to us →The questions that come up too late
01Is this an anomaly, or a data error?
Investigated, not deleted.
Outliers are checked against their source. Errors are corrected; genuine events are kept and labelled.
02Is this value missing, or never recorded?
Searched, not invented.
Found in another source, derived with the method shown, or left empty and marked with the reason.
03Why don’t these totals reconcile?
Tied back to source.
Sources are matched, aggregations rechecked, and variances resolved or explained.
04Who decided to change it?
A person makes the call.
Agents flag and propose. A person approves each change, or the rule behind it, and it is logged.

Curation project
We clean, reconcile and restructure the data, with changes reviewed and logged. You keep the curated data and the rules that produced it.
