About Stephane Marceau
Stephane Marceau is Managing Director of AI Ventures (also called Mila Ventures) at Mila - Quebec Artificial Intelligence Institute. Crunchbase lists his start there as May 2025, and Mila announced the appointment on July 9, 2025. Mila's bio says he spent more than two decades building, leading, investing in and advising tech ventures. It describes him as a serial tech CEO who co-founded and led several companies, some backed by venture capital and some by private equity.
Crunchbase lists him as co-founder and CEO of OMsignal from October 2011 to October 2016, and as co-founder and CEO of Theralive. It also lists him as President and CEO of Mobivox, and as a former Vice President at BCE (Bell Canada) and Chief Marketing Officer at Yellow Media. MarketScreener reports that he has been CEO of Thinking Capital Financial Corp. since 2019. Mila's bio says he held senior executive roles at large Canadian corporations and has served on boards.
He holds a Master's in Management of Technology from the University of Waterloo and a Bachelor's in Finance from the Universite du Quebec a Montreal. He is based in Montreal.
Mila and The Globe and Mail both describe him as an angel investor. Crunchbase records one personal investment, a seed round in Foko Retail, and lists Foko Retail as an exit. A September 2014 Foko press release named him, as CEO of OMsignal, among the angels in a $450,000 angel financing. That figure is the round total, not his own check. No other personal angel investments are public.
His current work is institutional rather than personal. Mila and Inovia Capital announced a US$100 million target Venture Scientist Fund, and BetaKit reported that Marceau will manage it. The Logic said he declined to say how much of the amount had been secured. The Globe and Mail reported that the fund targets pre-seed AI companies built on emerging research. That research comes from Mila and from the wider Canadian university ecosystem.
He also fronts Mila's Venture Scientist Bootcamp. It gives each founder a $10,000 stipend, with a maximum of two founders per team. He has said that the most important companies of the next decade will sit where advanced AI meets breakthroughs across STEM.
Public statements point to pre-seed, research-driven AI and deep-tech companies with Canadian roots. They also point to founders who are researchers or STEM experts moving into entrepreneurship. Mila says its incubated startups span health and biosciences, energy, climate, AI infrastructure and robotics. He has said Mila's goal is faster paths to founding, operator partners and early access to capital, compute and real-world testing. No personal check size has been disclosed.
