About this list
Consulting for a transformation program is the governance layer, and the documented work here shows where a governance engagement went after the workshop. Merantix Momentum has run Hamburg's AI innovation and governance process for the InnoTecHH fund since 2022, with 120-plus use cases evaluated in 2023, 19 in development and 8 scaled; at ams OSRAM it reports an AI center of excellence operational within three months, 30-plus use cases validated and 900-plus staff trained in 2022. Its Siemens Energy engagement is the other shape: a roadmap from 100-plus candidate use cases in a two-day workshop, two of three lighthouse cases taken forward. Babel was awarded the governance and monitoring office of the Andalusia AI Center in November 2025, covering use-case inventories, risk evaluation and EU AI Act compliance, too recent to carry a record. N-iX leads with APEX, an AI-adoption program with testimonials from WorkWave and First Student, though the curator notes its 28 percent AI-generated-code figure comes from a 30-engineer pilot. Unit8 describes a Foundry center of excellence at an unnamed financial institution.
The sorting question is conversion: of the use cases a governance process evaluated, how many reached production, and who ran the office in year two. Hamburg's program publishes that arithmetic; ask every other candidate for theirs. Separate AI consulting from digital-transformation consulting. Babel's case library leans to data warehouses and BI, ELCA Informatik's published stories describe process digitalization with no AI technique, and Netcompany's e-EFKA program is rules-driven automation. Those answer a different brief.

Expert Insight
Why AI transformation fit matters for AI Consulting
A program is judged by what it institutionalizes: a use-case pipeline, a platform, trained people and a governance process that outlives the consultancy.
The EU AI Act turns governance from a slide into an obligation: inventories, risk classification and documentation are program deliverables, and the agencies here have published work that carries them.
Platform economics decide whether the second year is cheaper than the first: ask what the documented programs did to the cost of the next use case, not the first.
