MasterWyse

Every large company knows the disease: the same customer in five systems under four spellings, and every downstream report built on the mess. Master data projects promise golden records, then quietly rot, because the next data load overwrites the fixes a steward spent months making. MasterWyse is built so that cannot happen. Steward decisions are recorded as durable rules, and every re-resolution reapplies them instead of erasing them.

The pipeline is the full discipline: blocking to find candidates, probabilistic scoring, clustering, and survivorship to assemble the golden record. Every match keeps its evidence, the per-field weights that produced it, so a steward reviewing a merge can see exactly why the system believes two records are one entity. AI proposes and explains matches; approving them stays a human act.

Underneath, a tamper-evident, cryptographically signed ledger holds the entire history of how each golden record came to be: every ingest, every resolution, every steward call, all re-verifiable after the fact. Master data stops being an act of faith and becomes a defensible record. Informatica and Reltio sell the year-long program. MasterWyse is open-core, and built to be stood up, proven, and owned.
