PARIS, February 13, 2026 – Proskauer is excited to announce that market-leading practitioners Matthieu Grollemund, Hélène Parent and Pierre-Marie Boya will be joining as partners in the Firm’s Private Equity and M&A Transactions Group in Paris later this month. The addition of the team reflects the Firm’s continued commitment to advising clients across the full spectrum of the private capital lifecycle.  

Matthieu, Hélène and Pierre-Marie bring extensive experience within private equity, M&A and complex cross‑border transactions across growing sectors. They advise a broad range of clients, including private equity sponsors, family offices, unicorns, industrial groups and management teams, further strengthening the Firm’s ability to support asset managers and global investors.

“We remain focused on anticipating our clients’ needs and are growing strategically in key practice areas and geographic markets to meet those needs,” said Firm Chairman, Tim Mungovan. “Matthieu, Hélène and Pierre-Marie will expand our presence in Private Equity and M&A, a high-growth priority practice, and our footprint in Paris, a dynamic market that is important to our clients. We are excited to welcome them.” 

“Our clients expect advisers who can navigate complexity with precision and foresight,” said Xavier Norlain. “This group’s sector focus in technology, healthcare and digital assets, plus complementary capabilities in infrastructure and growth investing, will deliver exactly that, and will meaningfully elevate our ability to assist investors operating in France and beyond.”

“Proskauer has built an outstanding private capital offering that is closely aligned with our clients’ business strategies and needs,” said Matthieu Grollemund. “We’re energized to join a team with such strong momentum and are eager to help drive the next phase of growth in Paris and further cement the Firm’s position as a leading advisor to the private capital industry.”

Proskauer continues to invest in Paris. The addition of Matthieu, Hélène and Pierre-Marie follows a series of lateral partner hires across key practice areas beginning in 2023, including corporate partners Xavier Norlain, Jeremy Scemama, Maud Manon and Matthieu Lampel, Agnès Rossi and Marcela Moraru in the Private Funds Group, Bryan Sillaman in the Firm’s International Investigations and Compliance practice, Gwenaël Kropfinger in the Tax Department, and Laura Bavoux in the Restructuring Group.
