About this list

AI consulting bought as a project is the phase that can end at a deck, and the documented work here shows where it went further. Merantix Momentum's reference pages carry both kinds: strategy engagements such as the ams OSRAM AI Center of Excellence (30-plus use cases validated, 900-plus staff trained) and a Siemens Energy roadmap from a two-day workshop, beside systems still running, with KRASS Optik's recommender serving 900,000-plus customers daily since 2021 and a Federal Chancellery proof of concept handed over for integration. Datatonic's Vodafone engagement produced an MLOps platform live in more than eight markets. Fast Data Science's Clinical Trial Risk Tool for the Gates Foundation was deployed publicly, open-sourced and published. OstraconAI splits the same way: Sanoma, Attendo and Eficode are assessments and roadmaps, while Singa is a lead pipeline live in week three. Datasparq's Leeds Bradford Airport workshop produced a roadmap, which the curator reads as opportunity identified, not value delivered.

The sorting question for a consulting project is whether the firm publishes the build that followed its advice. Read each write-up for its status word, since a roadmap and a proof of concept are different deliverables from an operated system, and ask what happened after the workshop. Then ask who delivered the production systems: the curator notes that seven of Merantix Momentum's 27 references are funded research consortia, that b.telligent's Data Science and AI practice is one of seven service lines, and that several OstraconAI headline numbers are forecasts rather than measurements.

Expert Insight

Why project-based fit matters for AI Consulting

1

A fixed scope protects both sides only when the acceptance criteria are written: ask for them before the rate, because a project without them becomes a retainer nobody agreed to.

2

The handover decides whether the project was an asset or a dependency: pipelines, evaluation sets and retraining procedures belong in the deliverables list.

3

The pilot-to-production gap is the main risk of project work in AI: the case studies here that describe operations and measured results are the ones that show an agency has crossed it.
