White Star Capital Closes $250M Fund IV for Series A and B Startups

White Star Capital, the global multi-stage venture firm founded in Montreal in 2014, has announced the final close of its fourth flagship fund. Fund IV is a $250 million USD vehicle (approximately $350 million CAD) that will lead Series A and B rounds for technology startups with global ambitions . The fund represents a 39% step-up from the firm's $180 million Fund III raised in 2019 .

Fund IV: Key Numbers and Focus

Fund IV writes initial checks of $5–15 million and reserves roughly half the fund for follow-on investments in its portfolio companies as they scale . The strategy leans heavily into AI-driven companies — including foundational AI models, vertical AI applications, and physical AI — while continuing to back software, fintech, digital assets, and broader technology sectors .

Importantly, Fund IV is not the firm's only new capital. Combined with White Star Capital's inaugural North American Seed Fund (a $50 million vehicle announced in late 2025) and several new special-purpose vehicles, the firm has raised more than $350 million in fresh capital since late 2025 to support founders from Seed through Series B .

Geographic Presence and Growth

White Star Capital was founded in Montreal in 2014 by Eric Martineau-Fortin and Jean-Francois Marcoux . It has since expanded into a global platform operating out of New York, London, Paris, Montreal, Toronto, Tokyo, and Singapore . Fund IV has a particular emphasis on North America and Europe, led out of hubs in New York, London, Montreal, Toronto, Paris, and Milan . The firm currently manages over $1 billion in assets and has invested in more than 100 companies .

Notable Portfolio Companies and Exits

White Star Capital's portfolio includes more than 100 companies, and the firm has completed over 22 exits . Notable exits include Dialogue Health Technologies (acquired by Sun Life) and Freshly (sold to Nestlé) . Other well-known portfolio companies include Butternut Box, Vention, and FINN .

Fund IV has already been deployed into early investments, backing six companies so far. These include Sequen (New York), Tetrix (Montreal), Veesion (Paris), OatFi, AMI Labs, and Trayd .

Investment Philosophy: "International From Day One"

White Star Capital's core thesis centers on backing "internationally ambitious" founders at Series A and B who have the ambition, talent, and product to build globally . The firm describes its approach as "international from day one" — using its multi-hub platform to help founders scale across markets .

Despite an evolving market, the firm states its thesis remains unchanged: partner with mission-driven technology founders building category-defining global companies, with a concentrated portfolio approach . Co-founder Jean-Francois Marcoux emphasized the firm's focus on defense, robotics, and industrial AI applications in an interview with La Presse .

Fund IV marks a significant milestone for the firm as it continues to deepen its commitment to early-growth venture investing across North America and Europe, with an increasingly sharp AI filter guiding its deal flow.
