About Giant Ventures
Giant Ventures is a London-based venture capital firm founded in 2018 by Cameron McLain and Tommy Stadlen. It invests from pre-seed through growth across Europe and the United States, championing ambitious teams using technology to reshape civilization, and organizes its work around three themes: climate, health, and what the firm calls inclusive capitalism. Coverage spans digital health, consumer, fintech, aerospace and defense, and industrial and energy technology, at pre-seed, seed, Series A and Series B and beyond.
The firm has raised roughly $350 million across four vehicles. Two 2020 funds put $50 million into seed and $50 million into growth. A $100 million seed fund and a $150 million climate growth fund followed in January 2024, the latter built for Series B rounds where hardware-heavy climate companies struggle to find capital. Giant says it is on track to deploy more than $1 billion into sustainable technology this decade.
Two things distinguish it. The first is the limited partner base, which pairs industrial corporates and institutions including BMW, Henkel, RIT Capital Partners, StepStone, Denmark's sovereign investment fund and The Nature Conservancy with individual backers such as Richard Branson and shareholders behind Booking.com, Unity and SoFi, giving portfolio company management teams commercial routes into incumbent buyers. The second is a bias toward repeat operators, with the firm known for backing serial company builders rather than first-time teams. Holdings include the mental health app Calm, regenerative agriculture carbon platform Agreena, battery storage developer Field, virtual ward provider Doccla, Carbon Robotics, Matta Labs and Odys Aviation.

Fund History
Giant Ventures was founded in 2018 by Cameron McLain and Tommy Stadlen and raised its first two vehicles in 2020: a $50 million seed fund and a $50 million growth fund, deployed in parallel across Europe and the United States. In January 2024 the firm announced $250 million in new capital, split between a $100 million seed fund intended to back roughly 25 companies and a $150 million climate-focused growth fund built specifically to address the Series B gap facing capital-intensive climate businesses.
That brings cumulative capital raised to roughly $350 million, against a stated target of deploying more than $1 billion into sustainable technology this decade. The limited partner base is unusually corporate and institutional for a firm this size: BMW, Henkel, RIT Capital Partners, StepStone, Cambridge Associates clients, Denmark's sovereign investment fund and The Nature Conservancy, alongside individual backers including Richard Branson and shareholders behind Booking.com, Unity and SoFi. The firm has made roughly 58 investments in six years.
