Gomumari launches Master Data Management AI Agent on November 2, 2026

Gomumari's service addresses a common problem: master data such as part, supplier, and department codes exists in many Excel ledgers and exported files, each created and updated separately, so which version is correct often lives only in a person's memory. The agent works in four stages—receiving data, matching records using common keys, mechanically verifying for spelling variations, duplicates, omissions, and discrepancies, and outputting results—while deliberately leaving final confirmation to people rather than aiming for full automation.

The company says the system was refined through master-data work in HR and sales management. In one case, a ledger that looked like a candidate for the authoritative source turned out, after checking with the department responsible, to be a price list created once a year and unusable for judging the latest state.

Gomumari offers the agent both as an AI agent implementation project with initial build and monthly operation, and as a specialized AI-BPO service where customers send data and receive deliverables, letting customers choose. The company says no new tool contracts are normally required, since implementation runs on infrastructure the customer already uses.
