About this list

In a transformation program the development work that matters is the platform that makes the second use case cheaper than the first. Datatonic built Vodafone's AI Booster MLOps platform on Vertex AI over 18 months; it is live in more than eight markets, cut proof-of-concept-to-production to about four weeks, and its reusable templates were released as open source. Netcompany's DSB system is a swarm of per-line delay models orchestrated by its PULSE platform, and its Copenhagen Airport luggage model has run since 2016 with drift monitoring and retraining. Merantix Momentum's KRASS Optik recommender has served 900,000-plus customers daily on automated retraining since 2021. Zühlke's Julius Baer engagement is the platform layer for generative AI in a private bank rather than a single use case, and Inspari's Danske Fragtmænd toll model runs as Python inside the client's own Snowflake.

Sort on what the platform leaves behind and who can add to it. Ask each candidate for the time and cost of the most recent use case added to a platform it built, not the first, and whether the templates, pipelines and retraining jobs are yours. Datatonic's open-sourced templates and Inspari's model inside your warehouse sit at one end; Netcompany's PULSE, EASLEY AI and PERSEUS sit at the other, where the curator notes to confirm the terms of moving off them. The curator also notes that KRASS and Boehringer Ingelheim run as open-ended engagements, so ask what monitoring and retraining cost after go-live.

Expert Insight

Why AI transformation fit matters for AI Development

1

A program is judged by what it institutionalizes: a use-case pipeline, a platform, trained people and a governance process that outlives the consultancy.

2

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.

3

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.
