Guillaume Briant


Co-head of the corporate M&A and private equity team in the Paris office, Guillaume advises public and private companies, as well as private equity funds, on a variety of French and international transactional matters.

Guillaume has more than 15 years' experience advising European and US investors on their inbound investments in France, whether through the acquisition of businesses or equity investments in high growth companies, and advising French corporate players in their international operations. He focuses his practice on the technology (including telecoms) and life sciences sectors, but also has extensive experience in transactions involving the agri-food, media, and manufacturing industries.

Guillaume regularly leads international transactions and quarterbacks cross-border teams of lawyers, including transactions involving Africa and other emerging market countries. In an increasingly complex international legal landscape, he is acutely aware of the issues arising from compliance and international sanctions in the context of corporate transactions.

Driven by a personal interest towards ESG issues, he developed a specific expertise regarding the governance of impact-oriented companies and the resulting operational implementation.

Admitted to the Paris and New York bars, his international background enables him to help bridge the cultural gap and assist his clients in navigating the French legal landscape.
