## About this market
An agent inside a transformation program is judged on what it owns after go-live, and the documented work here takes more than one shape. NextAI's Sophia at Percent, a Spanish real-estate network of 150 staff, put 31 automations and a voice agent into production between February and September 2026, with the median time to first contact down from 68 to 13.2 hours and 76 percent of answered calls ending as a structured lead—every figure labeled measured or estimated, and the economic results marked as awaiting reconciliation. Vstorm's agents run inside products: Mixam's order agent serves 10,000-plus daily users and about 100,000 orders a month, Synera's text-to-workflow agent sits behind a validator that rejects illegal code, and the Schmitt-Thompson clinical triage system is scored against 591 nurse-validated scenarios with its failure modes published. N-iX's APEX is a different purchase, a program for rolling AI coding tools into an engineering organization, with executives at WorkWave and First Student quoted by name and baselines such as test coverage rising from 55 to 81 percent.

Sort on authority and control. Ask what each agent may do without a person, what it escalates, and what stops a bad output reaching a customer: NextAI answers with a signed credential per agent that names its operator and permissions, expires in 90 days and can be revoked, which it calls a self-declaration rather than an audit; Vstorm answers with the validator and the scored scenarios. Then ask who runs the agent in year two. The curator notes that NextAI's contracts sit with an Estonian entity while delivery is Spanish-language from Valencia, that Vstorm anonymizes about half its portfolio, and that N-iX's named production references are proofs of concept, so ask each for a client you can speak to before the program starts.

### How is the AI transformation model verified?
Every agency here documents AI transformation 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 AI transformation engagements deliberately.

### Can these agencies embed consultants with our team?
2 of the agencies on this page document an embedded / team-extension working model. See the team-extension page for the full verified list, or check the engagement chips on individual profiles.
