Green Fusion GmbH has raised €12M in a Series A round

Our portfolio company Green Fusion GmbH has raised €12M in a Series A round to revolutionize heating systems with AI-powered optimization. 🔥

Led by HV Capital and XAnge, this funding round includes participation from us at Vireo Ventures, alongside existing investors BitStone Capital, Übermorgen Ventures, kopa ventures, and Brandenburg Kapital GmbH .

Green Fusion is tackling a massive challenge: inefficient, carbon-intensive, and costly heating systems. With Germany targeting climate neutrality by 2045 and rising CO₂ prices pressuring the housing industry, property owners are racing to make buildings more energy efficient.

Their cutting-edge software uses real-time monitoring and AI to optimize systems, reducing both heating costs and emissions. On average, their solution saves 16% on heating costs – translating to €233,000 annually per 100 systems.

With this financial boost, Green Fusion will scale operations, expand into new European markets, and advance renewable energy integration. By 2025, they aim to equip 3,000 apartment buildings with their software.

We’re proud to support Green Fusion on their journey to transform the housing industry and accelerate the heating transition – not just in Germany but across Europe.

Congratulations to the entire team on this incredible milestone!

ARTEM raises €1.5M in Seed funding led by Vireo Ventures

Big news from our portfolio!

We’re thrilled to announce our investment as lead investor in ARTEM Technologie AG’s €1.5M pre-seed round. With their CBAM Compliance & Carbon Reporting software, they are committed to driving the global transition to net-zero manufacturing.

This funding will help ARTEM enhance its comprehensive software and hardware platform, ensuring EU companies and global producers stay CBAM-compliant.

Starting Q1 2026, CBAM mandates CO2 reporting and certificate purchases for key imports like steel, cement, aluminum, fertilizers, electricity, and hydrogen. While the regulation aims to reduce emissions and combat carbon leakage, it poses significant challenges for importers and producers, particularly in monitoring, reporting and verifying primary emissions data across supply chains.

ARTEM simplifies this with seamless reporting solutions powered by real primary emissions data – and is aligned with our mission at Vireo Ventures to drive global transition towards a climate-resilient, decarbonized future.
Excited to be partnering with the impact-driven team: Nanxi Ding, Leo Rees-Murphy, and Ofir Weinstock

Has the Draghi Report Sparked a Shift in the EU?

Just two weeks ago, European Central Bank President Mario Draghi delivered a sobering but realistic assessment of Europe’s competitiveness in his latest report.

Draghi underscored that securing Europe’s future prosperity requires significant action—among them €800 billion in additional annual public and private investments through 2030. His message is clear: cleantech, digitalization, and electrification are vital to this mission.

We fully support Draghi’s vision. Increased investment in innovation and a better regulatory environment for start-ups will be critical to bolstering Europe as a competitive business hub.

Encouragingly, Ursula von der Leyen has signalled her alignment with these goals. Last week, she unveiled her team of commissioners and portfolios, which align well with Draghi’s proposals.

We are excited about these developments and remain committed to investing in Europe’s future.

Our latest investment in Lichtwart

We are excited to announce our latest investment in Lichtwart, a German company that is rethinking the way businesses manage their outdoor lighting installations

The three founders, Gregor Giataganas, Johannes Mailänder and Jackson Bond, set out to make exterior building-related lighting more energy efficient and easier to maintain, while significantly reducing operating costs, improving ESG criteria, and actively addressing the growing problem of light pollution.

The seven-figure round, co-led by Vireo Ventures and our friends at BitStone Capital, supported by better ventures, will allow Lichtwart to expand its feature set and launch its first major international project with one of the world’s leading manufacturers of illuminated signs – spanning several hundred locations on three continents 🌎

With a surging demand for energy efficient lighting and a market expected to grow substantially in the coming years, Lichtwart is ready to scale to become the global standard for lighting control and maintenance.

We at Vireo are very excited to accompany them on this journey.
Congrats to Gregor, Johannes and Jackson – this is a big milestone!
