Confidence is built on strong foundations. I partner with clients across transactions and the CFO agenda – turning complexity into clarity and finance functions into a source of value.

How Hortense is shaping the future with confidence

Every transaction is a defining moment — and I believe confidence at those moments comes from strong foundations. In my work, I help CFOs, boards, and Private Equity investors navigate the most complex chapters of their journey: post-acquisition integration, carve-outs, GAAP conversions, and exit or IPO readiness.

What drives me is not the technical complexity, but the people behind it. I partner with finance leaders to turn their function into a source of value — one that supports growth, withstands scrutiny, and creates optionality for the future.
