Jean-François Séguin is a partner in the Emerging Tech, Private Equity & Venture Capital and Corporate/M&A groups at Fasken. He advises high-growth companies as well as institutional investors on M&A transactions, equity financings, joint ventures and a wide range of other corporate matters. He is also a strategic advisor to tech startups wishing to raise capital, build administrative functions and/or expand internationally.

Prior to rejoining Fasken (where he started his career), Jean-François was Executive Vice President, Chief of Staff and General Counsel at Dialogue Technologies, a fast-growing digital health company based in Montreal. While at Dialogue, he also acted as Managing Director of Dialogue Deutschland GmbH in Munich and as a Director of Helios Dialogue GmbH, a Berlin-based joint venture with Europe’s largest private healthcare group. He managed Dialogue’s $40m Series B financing co-led by CDPQ and Holtzbrinck Ventures as well as Dialogue’s acquisition of DXA, a medical triage technology company leveraging artificial intelligence.

Previously, Jean-François was a Vice President in the investment banking team of Rothschild & Co and a Senior Associate in the private equity team of Clifford Chance LLP in London and in the Middle East. During those years, he worked on numerous cross-border transactions across a variety of industries and geographies such as the sale by Network Rail of its UK property business to Blackstone and Telereal for $2.4bn, the sale by SAB Miller of its Eastern European business to Japanese brewer Asahi for $10.7bn, the acquisition by General Electric of Alstom’s power and grid businesses for $18bn, the $1.3bn investment in Korean conglomerate POSCO by the Public Investment Fund of Saudi Arabia, the acquisition of Unilode by Swedish private equity powerhouse EQT from Brambles for $170m and the acquisition by Actis (a leading emerging markets investor) of renewable energy and oil & gas projects in Egypt, Senegal and Nigeria.

Jean-François started his career with Fasken after articling with the firm and spending a summer at the firm’s London office. His practice focused on private and public M&A. Representative transactions on which he worked on at Fasken includes advising: Canmarc REIT on its hostile takeover defense and subsequent sale to Cominar REIT for $904.4m, Héroux-Devtek on the sale of its Aerostructure and Industrial Products operations to Berkshire Hathaway’s subsidiary Precision Castparts Corp for $300m and Cossette on its hostile takeover defense and subsequent sale to Connecticut-based private equity fund Mill Road Capital for $115m. 

Jean-François has been actively involved in the community and has led major fundraising initiatives for the arts and cancer research. He currently is a member of the Board of Directors and the Executive Committee of the Montreal Cancer Institute, an organization supporting cutting-edge fundamental and clinical research on cancer. He previously served on the Boards of Directors of the Montreal Opera and MUTEK (an international festival blending music and technology).

Jean-François studied law and business at New York University and Université de Sherbrooke. He was a David Rockefeller Fellow at the Trilateral Commission, a scholar at the Center for Strategic and International Studies in Washington DC and also studied at the China University for Political Science and Law in Beijing.
