About this list
The longest documented embedding on this page is 10Clouds' work for Trust Stamp: more than five years of ML engineers placed on face-embedding, proof-of-liveness and KYC work, reporting to the client's own data-science lead. Stepwise's clearest record of the model is a named Clutch review from Ackwest Group, a US consumer-insights firm, covering a backend data platform with AI and ML work from January 2023 to January 2025 with six to ten Stepwise staff on it; the same review scores cost 3.0 against 4.5 overall. Brights documents continuity from the other direction: after the Kadroland and 7eminar multi-agent RAG consultant went live in three months, post-MVP work continued, and the Signal Intent calculator was built and then handed to the client's internal team.
The sorting question for a Warsaw team extension is who directs the engineers once they arrive. The Trust Stamp arrangement works because a client-side data-science lead sets the work; a buyer without one is buying a team that will set its own priorities, which is a different purchase. Ask each candidate whether its people have worked under a client's technical lead before, how seniority is held when someone rotates off in year two, and how much of the embedded work was the AI itself rather than the platform around it—the curator notes that much of the published work here is conventional software with AI labels on a few studies.

Expert Insight
Why team extension fit matters
Embedded work is an operating model, not a service line: an agency that documents it has already solved allocation, seniority and continuity, the three things that break staff augmentation.
The chip's evidence bar is self-description or a documented case study, so every listing here chose this model deliberately rather than matching a query.
Extension trades scoping overhead for velocity: no re-briefing, no phase gates, and the engineer is in your standup by week two.
Nearshore studios on this page built their model on this engagement shape; compare their published rates with a fully loaded local hire before deciding.
