Premier Etage
Premier Etage is a Nantes-based investment network led by Thomas Mathieu, backing early-stage French startups through regional co-investment partnerships.
Premier Etage
Premier Etage operates as a generalist investment company based in Nantes, France, and represents the pooled capital and deal-flow network of founder Thomas Mathieu and a small circle of co-investors. Mathieu's operational background includes co-founding Guest Suite, a software business, and that entrepreneurial exit informs the firm's willingness to back early-stage founders in Western France. The network is anchored in the Nantes tech ecosystem, with ties to innovation hubs La Cantine and _icilundi. The firm's investment posture is regional and opportunistic, with a focus on pre-seed and seed-stage French startups. Deal flow is sourced through personal networks and frequent co-investment partnerships with Sodero Gestion, Atlantic Business Angels Booster (ABAB), and Business Angels 35. One known portfolio asset is Qwarks, a French biotech company. The firm's small scale means deployment is sporadic — likely a handful of new positions each year — and concentrated in sectors where the members have personal operating experience. Premier Etage's team includes Jon Harr, an investor and Operations Director at Andøya Spaceport in Norway, linking the network to the European space infrastructure sector. No dedicated fund vehicles, regulatory filings, or public AUM disclosures exist for the entity, consistent with an informal syndicate structure rather than a fund manager. Recent activity remains undisclosed, as the firm does not publish a public track record. Structurally, Premier Etage is a hybrid of family office, angel syndicate, and professional network — a form common in French regional ecosystems but rarely documented by global data vendors. The firm's enduring edge lies in its deep integration with Nantes-based innovation communities and an investment committee that blends operational founders with infrastructure operators.

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.
Is Premier Etage structured as a single family office or does it operate more like a venture firm?
Premier Etage defies easy categorization. It is legally registered as an investment company but operates more like a hybrid of an angel syndicate and a professional network. There is no known family wealth anchoring the firm, and no formal fund structure exists. Instead, it pools capital from a small circle of operators and co-investors for direct startup investments.
What investment stages does Premier Etage typically target?
The firm focuses on pre-seed and seed-stage investments in French startups, consistent with the profile of its regional angel co-investors. One known portfolio company is Qwarks, a biotech firm, which suggests appetite for early-stage European life sciences. The firm's generalist mandate allows for opportunistic investments across sectors where members have direct operating experience.
Does Premier Etage maintain philanthropic structures, and how are they separated?
There is no public evidence of a dedicated philanthropic foundation or donor-advised fund associated with Premier Etage. The firm's activities appear entirely commercial, focused on equity investments in early-stage French startups. If philanthropic commitments exist, they are likely personal and not managed through the Premier Etage entity.
