What we said about each
Our take on Converteo
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…

Read the full assessment →Our take on Wavestone
Wavestone approaches AI from governance rather than from engineering, and for a regulated buyer that is the point rather than a limitation. The practice is built on DORA, NIS2, the EU AI Act and ISO 27001, with delivery attached to it. The published work follows: generative AI replacing manual steps in document processing at the Helvetia Group, a use-case prioritization exercise in wealth and asset management, a unified data operating model for a healthcare group built for compliance as much as…

Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
Converteo
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
Watch-outs
- 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
Wavestone
Strengths
- Publishes an average daily rate of €944, which makes budgeting possible before the first meeting
- AI delivery attached to a real regulatory practice—DORA, NIS2, the EU AI Act, ISO 27001—rather than sold beside it
- A listed consultancy of 6,000-plus people, so capacity and continuity are not the risk they are with a boutique
Watch-outs
- One named AI client (Helvetia) among several anonymized stories—ask for a reference inside your own regulatory perimeter
- The published AI work is governance, adoption and process rather than model building; check the split before scoping
