Exergon

The firm's website lists three founders — Charles Beigbeder, Giuseppe Sangiovanni, and Anna Teyssot — as the core investment team. There is no separate investment committee disclosed, suggesting decisions sit with this group. Beigbeder's background as a serial entrepreneur and founder of the Audacia management company gives him the most senior profile, but Exergon has not publicly specified a single decision-maker.

Charles Beigbeder is the founder of both Exergon and Audacia, a management company that runs growth private equity, real estate, and venture capital funds. Exergon describes itself as a dedicated pan-European energy transition VC, but the website does not detail the legal or operational separation between the two entities. Allocators should assume a shared parent infrastructure unless the firm clarifies otherwise.

Exergon's stated verticals are new nuclear, energy storage, and energy efficiency & AI. The firm does not publicly list any negative screens, but its portfolio of seven companies contains no pure-play consumer apps, no fossil-fuel transition plays, and no software-only SaaS outside of battery diagnostics. Geographically, all named portfolio companies to date are headquartered in France, the UK, or Italy.

The firm's website does not state whether it takes lead-investor roles. Ticket sizes of €0.3M to €8M, combined with a Seed-to-Series-B mandate, typically allow for both lead and co-investor positions in European deeptech rounds of the size its portfolio companies would raise. The firm mentions fostering 'synergies within our portfolio and with our industrial and financial partners,' which suggests an active co-investor network, but no specific co-investors are named.

Exergon lists a six-person scientific board that includes figures such as former IEA renewable energy head Paolo Frankl and ex-ENGIE executive Michèle Azalbert. The firm's about page states that it evaluates technologies 'through a rigorous scientific and economic lens,' but does not describe the board's governance role. It is likely a technical advisory body rather than an investment committee with veto power, though Exergon has not made that distinction explicit.

No. Exergon has not published an AUM figure or named its limited partners. The only public sizing data is its per-investment range of €0.3M to €8M, as noted on its own website. Without a disclosed fund size, the firm's total capital base and the concentration risk of any single LP relationship remain unknown to outside allocators.

Exergon describes itself as a multi-stage fund investing from Seed to Series B, which implies it reserves capital for follow-on investments in existing portfolio companies. The firm has not published a specific reserve ratio or stated a policy on pro-rata rights. Allocators evaluating a commitment should request historical follow-on percentages across its seven-portfolio-company history.
