Jérôme advises sponsors on the structuring, formation, and ongoing operations of private alternative investment funds (AIFs). His experience covers the full fund lifecycle—from designing structures and launching vehicles to supporting fundraising—across strategies including private equity, private debt, infrastructure, and real estate. He assists asset managers with establishing Luxembourg fund products such as RAIFs, SIFs, SICARs, and unregulated limited partnerships (SCSp), and supports institutional investors with AIF due diligence.

He routinely negotiates fund terms for sponsors and investors and has significant experience setting up managed accounts and co-investment vehicles. Recently, he has gained considerable exposure to evergreen and semi-liquid strategies targeting private wealth, including via RAIFs, Part II UCIs, and ELTIF structures.

Jérôme has also authored several publications in the regulatory field, including his article on “AIFMD and Private Equity” in the authoritative handbook: International Banking and Finance Law Series by Wolters Kluwer.
