About this list
Most agent work on this page is labeled by stage, and the stage matters more than the tag. Softblues' Roof Maker voice line is live, eight specialized agents answering every support call, while SofiaHR's ten fine-tuned Gemini Flash models, scoring candidates at 90%-plus agreement with expert analysts, run in beta across 10 clients. Twistag documents four chained agents at PepTalk, an inbound parser on Bedrock and semantic matching over 3,000-plus profiles in pgvector, and says itself that no outcome has been measured. Valletta's Helsingor engagement is an OpenClaw agent across Slack, Gmail and Calendar that cut research turnaround from two to three weeks to one day, per the client's own review. Transparity's bid-management agents at BMT are pilots by the client's description; Syncronika's AgenVIO platform launched in April 2026 with no client deployment described; Opinov8's RAILS platform publishes scenarios with no named deployment; Vention's most detailed AI studies describe its own internal tools; N-iX's client ML studies anonymize the client, and Satalia's tag covers optimization engines rather than language-model agents.
For a buyer embedding an agent engineer, the sorting question is who holds the evaluation set. SofiaHR's 90% figure exists because analysts graded outputs; PepTalk has no figure because nobody did. Ask which of your people will grade the agent's answers after the vendor's engineer leaves, whether prompts, traces and test cases are handed over in your repositories, and how many engineers would be assigned, since Twistag's Aralab build was one engineer and Valletta's offer is one embedded engineer.

Expert Insight
Why team extension fit matters for AI Agents
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.
Frequently asked questions
14 agencies in our directory combine verified team extension client evidence with documented AI Agents work. The current top-ranked are Pixelette Technologies, Vention, Transparity — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Published rates across this page's agencies run €20–130 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
Every agency here documents team extension work on its own site or in a published case study, describing the engagement structure rather than a service-list claim. We never infer the model from portfolio tone, so this list only contains agencies that operate team extension engagements deliberately.
