What Climentum Capital does

Climentum Capital is a Copenhagen-headquartered venture capital firm specializing in early-stage European climate hard tech. Founded in 2020/2021 by Morten Halborg, Stefan Mård, and Dörte Hirschberg, the firm manages Fund I, which launched in 2022 with €60M in LP commitments, and is preparing to launch Fund II in 2026. The firm operates as an Article 9 fund under the EU Sustainable Finance Disclosure Regulation, employing a dual carry model that ties financial returns to a fixed portfolio-level emissions reduction target of 1 MtCO2e. Climentum invests at Seed and Series A stages with €1-5M initial tickets, 10% target ownership, and up to €10M follow-on capacity, reserving roughly 50% of capital for follow-on rounds. It has executed 17 investments across 7 European countries through its Nordic-DACH Bridge thesis, with offices in Copenhagen, Berlin, Stockholm, Stuttgart, Oslo, and Helsinki.

The firm's revenue model is standard institutional VC: management fees on committed capital plus carried interest on realized portfolio exits. The portfolio spans industrial heat pumps (Enerin, Qvantum), agricultural AI (Nature Robots), industrial battery storage (Scale Energy), rail logistics (Rail-Flow), heating cable management (EQON), nuclear fusion (Novatron), electrolysis (JOLT), and composite recycling (Rodinia). The first realized exit was KNXT's acquisition by Studsvik AB in 2026. The senior team of seven to ten professionals combines institutional investing backgrounds (Skandia), industrial deep tech experience (Porsche, BMW, Ford), and consulting/scaling expertise (McKinsey, Rocket Internet), enabling thesis-driven sourcing and active portfolio support across financial, operational, and commercial scaling.

Climentum's go-to-market is relationship-based and thesis-driven rather than broadly marketed. Deal sourcing relies on the team's Nordic and DACH networks, co-investor relationships with firms such as Vireo Ventures, Antler, Bayern Kapital, Trill Impact, Azolla Ventures, and Johnson Controls, and thought-leadership content via its website and newsletter. Customer-facing activity is directed both at portfolio founders (deal flow and support) and at LPs (capital raising). The 2025 loss of General Partner Malin Carlström was partially offset by the additions of Jennifer Dungs as GP and Nathalie Öhlander as Principal.

Broad incumbents

• Breakthrough Energy Ventures: Bill Gates-backed, multi-billion-dollar climate tech venture fund investing globally across the same hard-tech decarbonization themes (heat, electricity, transportation, manufacturing) that Climentum targets in Europe. Same asset class, much larger scale, broader geographic mandate.
• Lowercarbon Capital: US-based climate tech VC fund deploying across the full climate stack from carbon removal to industrial decarbonization. Comparable asset class and climate-only mandate but US-centric and significantly larger fund vintages.
• Speedinvest: Vienna-based European early-stage VC with a dedicated Climate Tech & Industrial Tech fund. Larger multi-sector fund manager but overlapping DACH-based climate hard-tech mandate at comparable entry stages to Climentum.

Direct peers

• Planet A Ventures: Berlin-based early-stage European VC fund exclusively focused on climate tech startups. Closest direct peer to Climentum given similar European focus, seed/Series A entry stage, and climate-only mandate, with comparable fund size (€160M Fund I).
• Pale Blue Dot: Sweden-based climate VC fund investing in early-stage European startups tackling climate change, sharing Climentum's Nordic origin, seed/Series A entry stage, and focus on impactful climate solutions.
• 2150: Copenhagen-based early-stage VC investing in European startups that reshape how the world builds, moves, feeds and powers itself. Same Copenhagen base, similar hard-tech / decarbonization thesis, and overlapping Nordic sourcing network as Climentum.
• Clean Energy Ventures: US-based seed-stage climate tech fund investing in early-stage companies decarbonizing energy, mobility, and industry. Same climate-only, seed/Series A focus on deep decarbonization hard tech as Climentum, though focused on North America.
• Azolla Ventures: Climate-focused early-stage VC that co-led EQON's $6M seed round alongside Climentum. Comparable climate-only thesis, seed/Series A entry, and hard-tech focus with overlapping portfolio.
• Trill Impact: Nordic-based impact-focused VC that led Rail-Flow's €12.5M Series A alongside Climentum. Comparable early-stage impact mandate, Nordic presence, and direct co-investment relationship with Climentum on portfolio deals.
• The Footprint Firm: Climate-focused VC that co-led Enerin's €15M Series A alongside Climentum. Direct co-investment overlap on Climentum's portfolio, with similar early-stage climate hard-tech focus.
