Uniper: 27 days faster time-to-sign for candidates

Uniper (energy) reported this on 9 Sep 2026 in vendor case with a named customer (source). It belongs to the data and ontology layer.

What they built

A recruiting and hiring agent in Microsoft Copilot Studio, grounded in the Celonis Context Model (process-mining data on how hiring actually flows), used by recruiters and hiring managers.

The result

Average time-to-sign for candidates cut by 27 days; screening phase shortened by 13 days. Before production, the same prompts run on raw HR-system data returned generic answers, while the process-grounded agent named Uniper-specific bottlenecks.

The number covers recruiting and hiring process at Uniper after the agent went to full production; with/without-context comparison was a qualitative side-by-side test.

“With Celonis as our context layer, we’re building AI solutions that aren’t just tools we experiment with,” Uniper said.

The layer: data and ontology

Shared definitions of your metrics and records, used by both staff and agents.

  • One definition for every metric that matters
  • Linked objects across ERPs, CRM and documents
  • A log of human decisions and their reasons
