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.
Rigorous in execution.
Pragmatic in approach.
Easy to work with.

Not just advising, but actively involved. We structure, negotiate, drive and decide together. Every mandate handled directly — no layers, no dilution.
No conflicts of interest, no proprietary products to push, no cross-selling agendas — fully aligned with your objectives.
