Climentum Capital

What they fund

• Stage: Seed and Series A initial entry stages [1].
• Ticket Size: €1–5M initial ticket sizes [1].
• Sector: B2B hard tech companies for sustainable re-industrialization, focusing on climate and deep-tech innovations [1].
• Geography: Europe, with a core focus on the Nordics and DACH region [1].

Interconnection: The €1–5M ticket size and seed/Series A focus indicate a commitment to early-stage hard tech, requiring significant follow-on capital (50% kept for follow-ons) to scale these capital-intensive ventures.

Investment thesis

Climentum Capital backs un-hyped early-stage hard tech companies to build the industrial backbone of a resilient, competitive, and sustainable Europe [1]. The firm drives fundamental industrial transformation rather than incremental change, focusing on decarbonizing Europe’s highest-emitting sectors while strengthening the continent's resilience, competitiveness, and independence from external supply chains [1].

• Industrial Decarbonization: Investing in hard tech solutions that deliver real decarbonization potential across Europe's most polluting industries [1].
• Supply Chain Resilience: Backing companies that develop flexible, low-carbon, circular, and robust supply chains to reduce European dependency on external resources [1].
• Nordic-DACH Bridge: Leveraging the Nordics as a climate innovation hub and the DACH region as Europe’s industrial heartland to scale B2B hard tech commercially and operationally [1].

Credibility: The firm's homepage explicitly outlines its focus on industrial transformation, supply chain resilience, and the Nordic-DACH bridge, supported by its portfolio of hard tech companies tackling industrial emissions [1].

Value add

Climentum provides operational and commercial support to scale early-stage hard tech across climate and Europe's industrial landscape [1]. The firm leverages its local presence and shared mission with partners across Europe to drive European-scale impact [1].

Fit verdict: Ideal for B2B hard tech founders seeking capital and strategic support to scale industrial decarbonization solutions in Europe.

Notable investments & exits

• Portfolio Composition — The portfolio includes companies focused on accelerating offshore wind deployment via software and data, providing modular high-temperature heat pumps for industrial process heat, and developing full-stack software suites for rail infrastructure.
• Energy & Nuclear — Climentum has invested in companies delivering SMR-based (Small Modular Reactor) nuclear power projects and developing high-performance electrodes for more efficient electrolysis, highlighting a focus on critical energy infrastructure.
• Agriculture & Materials — Investments include ventures enabling fully autonomous farming through advanced SLAM-based navigation and companies that transform composite waste into sustainable construction materials, addressing supply chain stability and circularity.
• Exit Activity — The firm’s website lists "Exit" as a category within its portfolio insights, indicating a track record of successful liquidity events, though specific names of exited companies are not detailed in the provided text.

Strategic implications

Climentum's focus on the Nordic-DACH bridge positions it to capitalize on the Nordics' climate innovation and the DACH region's industrial base, creating a unique value proposition for hard tech startups. The Article 9 status and dual carry model signal a strong commitment to measurable climate impact, which could attract LPs focused on sustainable investing but may require rigorous impact reporting. The 50% follow-on reserve indicates a strategy to support portfolio companies through scaling, reducing the risk of dilution and ensuring long-term alignment with founders.

Where they could go further

Climentum could enhance its value proposition by establishing a dedicated commercialization support program to help hard tech startups navigate regulatory and market entry challenges in Europe. Expanding its network of strategic partners beyond the Nordics and DACH could help portfolio companies access broader European markets and supply chains. Developing a standardized impact measurement framework could strengthen the firm's Article 9 credentials and attract more impact-focused LPs.
