Foresight and regulatory anticipation, quality of reporting

Founded in 2016 by Caroline Ruellan, SONJ Conseil keeps on working in partnership with its clients – listed and unlisted companies, family businesses, investment funds and shareholders – to design tailor-made strategies for value creation.

Our unique approach combines an in-depth knowledge of shareholder dynamics with a thorough understanding of the functioning of corporate governance bodies. We are at the heart of the market’s reflections and provide a forward-looking perspective on regulatory changes and market trends.

We advocate for a governance at the service of the company’s strategy, strategic orientations and projects, in order to create, enhance and share value.
