Antin Infrastructure Partners

Alain Rauscher, Mark Crosbie, and Mélanie Biessy co-founded Antin and remain senior partners with authority over investment strategy (per the firm's founding disclosures). Each fund series has its own investment committee staffed by the senior partnership team. Operational deal execution is led by managing directors based in Paris.

Antin’s founding team built operator relationships across Europe’s regulated sectors before establishing the firm, giving them early access to corporate carve-outs and secondary-market concession sales. The firm targets bilateral transactions and limited-auction processes rather than broadly marketed mandates. This network-based model produced the firm’s first investments in French district heating and fibre operators.

Antin structures its funds to accommodate selective co-investment by limited partners, a feature disclosed to institutional investors at fund formation. The firm has historically maintained control positions in each asset, reserving minority stakes for co-investors on a deal-by-deal basis. External GP partnerships are not a principal sourcing channel, given Antin’s direct origination model.

Antin operates as a direct infrastructure investor, taking equity and occasionally preferred or debt positions in operating companies and concessions. The firm does not market a fund-of-funds program and has no publicly disclosed commitment to third-party infrastructure funds. Its limited partnerships are formed to hold direct portfolio assets.

Antin has historically not invested in greenfield project development, exploration-stage energy assets, or merchant power generation without contracted revenues. The firm's publicly disclosed portfolio excludes social housing, pure-play real estate, and early-stage technology ventures. These exclusions align with the concession and regulated-asset focus articulated at the firm’s founding.
