The Company That Sells the Single Source Becomes a Row in Someone Else's

On 18 November 2025, Salesforce completed its roughly $8 billion acquisition of Informatica, the vendor whose platform includes Master Data Management. The seller of the single source of truth has been merged into a larger one. Survivorship rules to follow.

Salesforce announced on 27 May 2025 that it would acquire Informatica for about $8 billion in equity value, at $25 in cash per share, and completed the deal on 18 November 2025. Informatica's platform — data catalog, governance, quality, metadata management, and explicitly 'Master Data Management (MDM) services' — now sits inside Salesforce. A company that sold the authoritative version of 'customer' is now an entry someone else has to reconcile.

This matters because integration is exactly the problem MDM exists to solve, now applied to the vendors themselves. Two large platforms each carry their own definition of an account, a contact, a customer. Folding one into the other does not merge the definitions; it schedules the merge. The hard question Informatica's tools were sold to answer — which record wins when two sources disagree — is now an internal project at the acquirer, on a deadline nobody outside can see.

The field reveals itself in the recursion. The 'single source of truth' is not a destination a tool ships you to; it is a maintenance state someone has to fund forever, including the people who sell it. When the MDM vendor becomes line items in an acquirer's master, you can see the thing plainly: there is no final master, only the most recent owner. The golden record has a parent company now, and the parent has its own golden record.

Watch how the two data models actually reconcile, not how the press release narrates it. The phrases to distrust are 'unified data foundation' and 'trusted data'; the thing to look for is who owns the customer entity across both stacks and which survivorship rule decides conflicts. If that owner is named and the rule is written, the merge is real work. If it is a slide, you are watching the fourth definitive master being declared while three others keep running.
