Marine Charbonnier

A decade in investment banking and private equity — first structuring and executing deals at Deutsche Bank, then assessing, negotiating, owning and selling them as an investor at Carlyle's European Buyout fund. Over a hundred opportunities assessed and 20+ closed.

Sunstone Advisory is built on that experience, and the conviction that the best transaction support comes from understanding not only how processes work, but how investors really think.
