Climentum Capital is a venture capital firm dedicated to investing in European early-stage companies that are actively reducing CO₂ emissions within industrial sectors. Established in 2020, the firm focuses on hardware and deep-tech solutions, augmented by software, which they refer to as 'hard-tech'. Their investment strategy targets six key sectors with the highest potential for CO₂ emission reductions: Next Generation Renewables, Food & Agriculture, Industry & Manufacturing, Buildings & Architecture, Transportation & Mobility, and Waste & Materials.

Climentum Capital operates across Europe, with offices in Stockholm, Copenhagen, and Berlin, and primarily invests in Seed and Series A stages, offering initial investments ranging from €1 to €5 million. A distinctive feature of their approach is a double incentives structure, where both CO₂ emission reductions and financial returns are considered, ensuring that investments contribute meaningfully to climate mitigation efforts. The firm's team is based in some of Europe's strongest climate tech hubs: Berlin, Copenhagen, Stockholm, and Oslo, and is known for its gender-balanced partner group consisting of two women and two men.
