LONDON — Integrated communications and marketing agency Prosek Partners has hired Matthieu Roussellier as a managing director in its London office.

Roussellier joins the agency from PAI Partners, a European private equity firm, where he had served as head of communications since 2019. Before PAI, he held senior in-house and advisory communications roles, including at global investment firm Permira, law firm Latham & Watkins and Greenbrook Communications, a specialist communications advisory for investment firms.

Managing partner Jen Prosek said: “Matthieu’s deep private markets background, combined with his experience in both the London and European markets, makes him an excellent addition to Prosek. His track record of building integrated communications programmes for private markets firms as well as leading entrepreneurial teams will be a perfect fit for the strong team we have in London. We’re thrilled that he’s joined us as our European offering continues to grow.”

The senior hire follows a number of recent senior additions to Prosek’s private markets and special situations practice, including hiring former Finsbury Glover Hering MD Phil Walters.

Prosek was recently named as one of the world’s leading M&A advisories in the Mergermarket Global M&A rankings. In October last year, the firm – which has more than 350 employees across its six US offices and its bases in London and Cape Town – added a web3 offer.
