Data Governance & MDM
CRM & Data / Data Governance & MDM

Clean data is not an accident -- it is a governance model

Master data management, ownership rules, validation policies, and stewardship workflows that keep your CRM accurate at scale. Built once, maintained forever.

Business challenges

Why Data Governance & MDM projects fail

01

No single source of truth

Account data lives in CRM, ERP, support desk, and spreadsheets -- all saying different things. Nobody trusts any of them. Reports require manual reconciliation every month.

02

Duplicates accumulate faster than you clean them

Teams deduplicate quarterly. Duplicates return within weeks because the root cause -- no creation rules -- is never fixed. The problem compounds year on year.

03

Nobody owns the data

When everyone owns data, nobody does. Fields go unmaintained. Picklist values multiply without governance. Required fields get bypassed with dummy entries.

04

Compliance risk from dirty data

GDPR and GDPR/CCPA require you to know exactly what personal data you hold, where it came from, and who can access it. Dirty CRM data makes this impossible to demonstrate to a regulator.

All case studies

Celumai built a governance framework that reduced our duplicate rate from 34% to under 2% in 90 days. More importantly it has stayed under 2% for 18 months since -- because the prevention rules mean duplicates cannot be created in the first place.

Insurance Group

We had 5 source systems all claiming to be the master record. Celumai designed the MDM layer that made Salesforce the undisputed single source of truth. Reports are now trusted across the entire business for the first time.
