The Buy Side

The analytical
mandate.

Rigorous structuring. Deal logic. The Carlyle years — assessing, negotiating, owning.

Sun · Stone

The Sell Side

The relational
outcome.

Founder accompaniment. Exit preparation. The relationships that close deals.

M&A Advisory

Structuring the
deal.

Buy-side and sell-side mandates handled with the rigour of a PE investor. Valuation, negotiation, documentation — managed end to end. The Carlyle angle: understanding what the counterpart is really thinking.

Portfolio & Exit Support

Preparing the
exit.

For founders and investors who need a partner embedded in their team — not a distant advisor. Value creation, add-on acquisitions, equity story refinement, and exit process management built around the outcome that matters to you.

Fundraising Advisory

The IB
discipline.

Structuring the equity story, driving the process, managing investor follow-up — with the rigour of Deutsche Bank deal execution. A fundraising that positions you correctly from the first meeting to the term sheet.

Why it matters

Your capital.
Your terms.

Founders raising capital are negotiating with investors who do this every day. Sunstone Advisory puts the same expertise on your side — the perspective of someone who has been in the investor's seat, reading hundreds of equity stories and deciding which ones get funded.

No conflicts of interest. No proprietary products. No cross-selling agendas — fully aligned with your objectives.

The Founder
Marine has been on both sides
of every table.
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.
