Frequently asked questions

Who runs investment decisions at Premier Etage?

Investment decisions appear to be made by founder Thomas Mathieu in coordination with the broader Premier Etage investor network. The network includes Jon Harr, Operations Director at Andøya Spaceport, and draws on co-investors from regional angel networks such as Atlantic Business Angels Booster and Business Angels 35. The firm does not publicly disclose a formal investment committee structure.

How does Premier Etage source proprietary deal flow?

Deal flow comes through the personal networks of Thomas Mathieu and the firm's members, anchored in the Nantes tech ecosystem. The firm is plugged into local innovation hubs like La Cantine and _icilundi, and frequently co-invests alongside Sodero Gestion, Atlantic Business Angels Booster, and Business Angels 35. This regional footprint provides early access to French startups that are not widely shopped to institutional funds.
