## About this market
Sometimes the right engagement is not a project but people: machine-learning engineers, data engineers or applied scientists working inside your organization for months or years, on your backlog and under your product leadership. Every agency on this page documents that working model on its own site or in a published case study, and the chip is never inferred from portfolio tone. The evidence bar is deliberately different from the rest of this register, because embedded work only holds up when the agency has built its operations around it: stable allocation, people senior enough to work without agency-side supervision, and pricing that survives month twelve.

The documented engagements show what the model looks like at scale. N-iX has run a dedicated data team for the in-flight connectivity operator Gogo since January 2017, covering big data, data science and BI operations on AWS. craftworks' data scientists have worked inside voestalpine High Performance Metals' own data teams at its production sites since September 2020, quoted by the client's Head of Data Science and AI. Ultra Tendency states that it is wholly responsible for the architecture, implementation and testing of SPACE, the statistical production platform the European Central Bank runs across the eurozone's national central banks. In The Pocket describes a blended-team modernization of Melexis' chip-test software, and Marionete's MLOps factory for AXA was adopted across the insurer's business units.

When does extension beat a scoped build? When the work is continuous rather than shaped: a data platform that needs a resident owner, a machine-learning team that is two engineers short, a scale-up that cannot hire fast enough. Central European studios on this page, in Prague, Warsaw and Budapest, built much of their model on exactly this engagement shape. Ask three things before signing: who exactly is allocated, what the replacement policy is when the fit is wrong, and what the minimum commitment is. Scores rank portfolio quality and credibility; placement is never sold.

## Questions buyers ask

### What counts as team extension on this page?
An explicitly documented embedded working model: the agency describes joining or embedding with client teams on its own site, or a published case study documents the engagement structure, such as a dedicated data team run for years inside a client. It is never inferred from portfolio tone. The chip exists only where the agency itself evidences the model, a stricter bar than a 'dedicated teams' line in a service list.

### What does an embedded AI engineer cost compared to hiring?
Monthly pricing derives from the hourly bands on each profile and on our rate index. Against a senior hire's fully loaded cost plus months of recruiting, extension wins on speed and flexibility; hiring tends to win past the eighteen-month mark. Most teams use extension to bridge exactly that gap, and the profiles here show which agencies publish a rate at all.

### How is team extension different from a retainer?
A retainer buys ongoing agency capacity on the agency's side; team extension puts named engineers inside your team, working your backlog under your leadership. Extension suits continuous product or platform work; retainers suit recurring but bounded needs such as model monitoring, advisory or a stream of scoped deliverables. Some agencies document both models on their profiles, and the retainer page lists the ones that document that model.

### How fast can an embedded engineer start?
Agencies operating this model typically staff within two to four weeks. The practical questions to ask are seniority guarantees, the replacement policy if the fit is wrong, and the minimum commitment, with three months common. That is still months faster than a senior machine-learning hire in any European market.
