## Curator assessment
Reviewed 2026-08-05 by Gabor Kiss against published evidence.

Sharlie, the voice agent behind Orange's Sosh brand, is the most completely documented build in this register, and the detail is the point.

Converteo committed to a voice-to-voice architecture in April 2024, before the model reached general availability, specifically to avoid a later migration off a speech-to-text pipeline—a decision that bought roughly one second of latency against three. Around thirty specialized agents hand off between themselves, escalate to a human, and act on Orange's catalog, billing and account systems rather than only answering. Validation was modeled on how call-center advisors are trained. Virtual clients replay conversations at volume against an LLM-as-a-judge scoring price accuracy and brand posture, and an AI-specific bug bounty ran with around forty white hackers before launch. It went to production on 16 March 2026 with a mechanism to stop it.

The rest of the library is a decade of measurement and pricing work with named clients: Carrefour, Leroy Merlin, L'Oréal, ENGIE, BUT, Picard, Arkema.

The caveat is that this depth is exceptional rather than typical—most of the other cases describe data and marketing engineering, not AI.

### Key strengths
- One engagement documented end to end, including the architecture decision, its latency cost, the evaluation rig and the kill switch—no other agency here publishes at that level
- Evaluation as a discipline rather than an afterthought: virtual clients, an LLM-as-a-judge scoring price accuracy and brand posture, and an AI bug bounty before exposure to customers
- Ten-plus named clients across retail, energy and industry, with the work described case by case rather than listed as logos

### Good to know
- Outside the voice-agent work, most published cases are data and marketing engineering—confirm which practice your engagement lands in
- No headcount, founding year or rates published; scale and price both have to be established in conversation
