Private Capital Journal (2025-01-16) describes Vasco as "led by Guillaume Jacquet and Sébastien Rothlisberger" in its brief on the US$8 million seed round.

What did Sébastien Rothlisberger do before Vasco?

The same article says Lightspeed had bought Jacquet's first startup, ChronoGolf, in 2019, and that Lightspeed is now a Vasco customer.

Where is Sébastien Rothlisberger based, and what is his role today?

Boreal Ventures' team page, read 2026-10-16, lists "Seb Rothlisberger, Co-Founder & CTO @ Vasco" in its Boreal Guild, which the page describes as Boreal Ventures investors who are former founders and experienced operators. Vasco is based in Montreal, but no fetched page states where Rothlisberger himself lives, so no city is recorded. Vasco's own website could not be read on 2026-10-16 (it returned 403), so its team page was not checked.
