It takes about three weeks and a budget most people don't have, so most of us just guess instead. Yoann and Ludo built Sunzu around a different idea: feed in the customer data a business already has, and get back AI models of those customers you can actually interview. Ask about your pricing. Show them your homepage and see where they get lost. Test three ad versions before spending a franc on any of them. Answers in seconds instead of weeks. The obvious question is whether it works, or whether it's just a confident machine telling you what you want to hear. They've spent months benchmarking their AI customers against real human studies. They'll show the numbers, including where it gets things wrong and when you still need to go talk to actual people. No technical background needed. If you sell anything to anyone, or you're trying to work out which parts of your work AI is genuinely coming for, this one's worth your evening. ## **Speakers** **Yoann Lemain** — Head of Product at Sunzu. Digital innovation for a Swiss watch brand you know, payment products used by millions, one startup taken from seed to Series A. **Ludovic Lafole** — Head of Technology at Sunzu. 14 years building software and AI systems, from national media to CTO roles in B2B SaaS. ## **Agenda** 18:30 — Doors open, welcome 19:00–20:00 — Presentation 20:00 — Networking, plus test drives of Tesla cars around the city ## **Venue** Tesla, Centre Confédération, Geneva. Thanks to Tesla for hosting us. Bring your driving licence if you want to take a car out. No licence, no drive, and there's no way around it on the night. ## Details - **Start:** 2026\-08\-25T16:30:00\.000Z - **End:** 2026\-08\-25T20:00:00\.000Z - **Location:** Tesla Store, Rue de la Confédération 8, 1204 Genève - **Attendance:** mixed - **Language:** en - **Price:** Free - **Audience:** Open to all - **Event page:** - **Contact:** Nicolas Dinh Canonical:
