About Antin Infrastructure Partners

Founded in Paris in 2007 by Alain Rauscher and Mark Crosbie, Antin has grown from a specialist European investor into a listed infrastructure private equity firm with six offices worldwide. Its current platform spans Flagship, Mid Cap and NextGen strategies.

Antin invests in Europe and North America across energy and environment, digital, transport, and social infrastructure. The firm works closely with portfolio-company management teams on operations, financial performance, service quality, and health and safety.

Its differentiator is an active value-creation model focused on essential infrastructure businesses rather than passive asset ownership. The third-party blurb should be updated because Antin’s stated investment geography is Europe and North America, not Asia-Pacific.
