Extantia Capital, a venture capital firm dedicated to climate tech, has closed its flagship Article 9 fund at €204 million. The fund saw support from institutional investors, including sovereign wealth funds, pension funds, insurance companies, and family offices.
Founded in 2020, Extantia targets high-impact opportunities within the climate sector, investing in both software and hardware solutions that are poised to drive significant change. The firm concentrates on Seed to Series A funding rounds, typically investing between €1-5 million in early-stage companies.
With headquarters in Berlin and a team spread across the UK, Germany, and Israel, Extantia’s investment focus remains primarily within Europe.
“We are on the verge of a new industrial revolution,” says Sebastian Heitmann, Partner at Extantia. “Industry-leading companies recognise this opportunity and are working to build resilient supply chains, adopt low-carbon products, and, above all, drive solutions that fuel economic growth. That’s exactly where we come in. We partner with true leaders who drive mass adoption with faster, better, and more affordable solutions that also happen to be green. We will continue to see this sector mature, and we’re excited to support the next phase of growth.”
Extantia’s portfolio covers over 20 climate-forward innovations, with notable investments in companies like Reverion, which is developing reversible carbon-negative power plants and recently secured €58 million in Series A funding. Another standout is INERATEC, an e-fuel leader that closed over €120 million in Series B funding, helping scale their ‘drop-in’ e-fuel production. BeZero, a carbon ratings agency, is also part of Extantia’s portfolio, attracting follow-on funding from top-tier growth investors.
“There is no impact without scale,” says Yair Reem, Partner at Extantia. “That’s why we focus on providing founders hands-on support in commercialisation, organisational growth, and fundraising. As entrepreneurs and operators who’ve built and exited companies we understand where the pain points are and work together with our founders to facilitate accelerated growth – both for deep tech and high-impact software solutions.”
With approximately €300 million in assets under management, Extantia operates two primary strategies: Extantia Flagship, which invests directly in climate tech startups, and Extantia Allstars, focusing on supporting other venture funds within the climate sector. The firm’s investments aim to capture near-term market opportunities while setting the stage for long-term industry transformation.
