Antin Infrastructure Partners

Alain Rauscher, Mark Crosbie, and Mélanie Biessy serve as Managing Partners and sit on the firm's investment committee. They co-founded the firm in 2007 after leaving Goldman Sachs's infrastructure banking group. Day-to-day asset management and operational improvement programs are led by a team of investment professionals distributed across Paris, London, New York, and Luxembourg.

Antin relies primarily on bilateral and off-market negotiations, leveraging its Paris headquarters and the Goldman Sachs-originated networks of its founding partners to access European and North American infrastructure assets before they reach broad auctions. The firm's control-oriented strategy and reputation for operational engagement often position it as a preferred buyer for corporates divesting non-core infrastructure subsidiaries.

Antin listed its management company on Euronext Paris in September 2021, making it a publicly traded general partner rather than a pure private partnership. The founders retain significant board control, and the investment committee remains exclusively populated by the partnership. This hybrid structure provides permanent balance-sheet capital for GP commitments while keeping fund-level investment decisions insulated from public-market pressures.

Antin invests exclusively through direct, control-oriented equity positions in mid-to-large-cap infrastructure assets. It does not operate a fund-of-funds program, nor does it make LP commitments to third-party infrastructure managers. The firm's flagship and NextGen vehicles both deploy capital directly into operating companies and project platforms.

Antin's flagship funds target established, cash-flow-generative infrastructure assets with enterprise values typically between €200 million and €2 billion. The Antin NextGen fund, launched in 2023, targets smaller mid-market opportunities below the flagship fund's minimum equity check, though still in operational, post-development-phase assets rather than greenfield projects.

Energy and environment represents one of Antin's four core investment pillars, alongside digital, transport, and social infrastructure. The firm has invested in rolling stock, renewable generation platforms, and energy-efficiency service providers. Antin does not exclude conventional energy assets but the firm's public materials increasingly emphasize decarbonization-linked infrastructure.

Antin rarely co-invests alongside competing infrastructure managers on equal footing, as the firm prefers control positions that allow its operational-improvement playbook to be implemented without negotiation with a peer GP. The firm will occasionally partner with sovereign wealth funds or pension plans as minority co-investors on large-cap transactions where equity diversification is necessary.
