Converteo's voice agent for Orange's Sosh brand is the deepest build published by anyone on this page: a voice-to-voice architecture committed before the model was generally available, roughly thirty orchestrated agents wired into catalog, billing and account systems, and an evaluation rig of virtual clients and an LLM-as-a-judge behind it. Artefact builds on cloud and model partnerships—Databricks for Nexans' data foundation, Google Cloud for VINCI Airports across seventy sites. Wavestone builds inside regulated estates, where the documentation matters as much as the model. AI Sisters builds agents alongside client teams rather than for them; Mozza embeds senior engineers directly; McLeuker ships onto its own multi-agent platform or rebuilds it inside your stack. Three more have since joined: Preste builds computer vision and anomaly detection as an NVIDIA embedded partner and names Idemia and Siemens Healthineers, Serokell pairs functional-programming engineering with machine-learning delivery, and FFFACE.me works the consumer end, building the real-time AI clothing try-on used at the H&M x Stella McCartney launch. Only one firm here publishes a figure at all, so anchor the conversation against the European range on our rate index early. The question specific to this market is who operates the system afterward: several of these firms hand it to your team by design, which changes both the price and the skills you need in-house before you start. ## Questions buyers ask ### How much do AI Development agencies in Paris charge?
