Voyager Ventures Closes $275M Fund II, Signaling Confidence in Europe’s Energy and Compute Future

In a powerful statement of conviction about Europe’s technological trajectory, Voyager Ventures has announced the successful closure of its $275 million Fund II, bringing the firm’s total assets under management to $475 million across North America and Europe. This significant capital raise comes at a pivotal moment when the continent is positioning itself as a global leader in energy software and next-generation compute infrastructure.

Founded in 2021 by Sarah Sclarsic and Sierra Peterson, Voyager Ventures has carved out a distinctive niche in the venture capital landscape by focusing on what they call “the base layer of the economy”—the foundational technologies that will determine how societies produce energy, manufacture goods, source critical materials, and deploy artificial intelligence in physical systems.

“We launched Voyager in 2021 to invest early in the foundational technology companies for durable economic growth,” Sclarsic explained. Her words carry particular weight in today’s volatile economic climate, where traditional growth models are being questioned and new paradigms are emerging. The market validation they’re witnessing spans multiple sectors: energy systems that can handle increasing demand from AI workloads, critical materials supply chains that reduce geopolitical dependencies, advanced manufacturing processes that slash emissions, and AI systems specifically designed to optimise physical infrastructure rather than just digital interactions.

Peterson’s perspective frames the investment thesis in even starker terms. “The economy of the past was built on finite fuels and brittle processes that will continue to hamper prosperity until we transcend them. We’re investing in technology that simply performs better.” This isn’t merely incremental improvement—it’s a fundamental reimagining of how economic value is created and sustained in an era of climate volatility and technological acceleration.

The scope of Voyager’s investment strategy reveals the breadth of this transformation. Their Fund II targets six interconnected domains: Energy and Efficiency systems that can balance intermittent renewables with growing baseload demands; Materials Production technologies that enable circular economies and reduce extraction dependencies; Software and AI solutions that bring intelligence to physical infrastructure; Mobility innovations that reimagine transportation beyond fossil fuels; the Built Environment sector that encompasses everything from construction to urban systems; and Carbon Management technologies that go beyond mitigation to create value from emissions reduction.

What makes this fund particularly noteworthy is how it reflects Europe’s unique position at the intersection of several critical trends. The continent faces some of the world’s most ambitious climate targets while simultaneously experiencing explosive growth in data centre demand driven by AI development. European manufacturers are under pressure to decarbonise while maintaining competitiveness against Asian and North American rivals. Meanwhile, energy security concerns, amplified by recent geopolitical disruptions, have made local, resilient infrastructure a strategic imperative rather than a luxury.

Voyager’s portfolio already demonstrates this multidimensional approach. Companies like Allie are working on advanced energy storage solutions that could solve renewable intermittency. Anthro Energy focuses on next-generation battery technologies that promise higher energy density with fewer critical minerals. Arbour Energy develops software platforms for optimising distributed energy resources. Clean Baseload Power tackles the challenge of providing reliable, emissions-free electricity at scale. Zero Emissions works on industrial processes that eliminate carbon output entirely, while Astro Mechanica brings advanced manufacturing techniques to aerospace applications.

The fund has already begun deploying capital, with investments in companies that exemplify Europe’s emerging strengths. ENAPI, which recently secured €75 million in seed funding, is transforming electric vehicle charging infrastructure with intelligent software that optimises grid integration. Leeta Materials Home is pioneering new approaches to sustainable building materials, while Electroflow Technologies is developing innovative solutions for managing the complex flows of electrons in modern power systems.

This investment activity comes against a backdrop of intensifying competition for technological supremacy. The United States continues to dominate in AI model development and semiconductor design, while China maintains its lead in manufacturing scale and battery production. Europe’s competitive advantages lie precisely in the areas Voyager is targeting: sophisticated energy markets with deep integration of renewables, world-class engineering talent, strong regulatory frameworks that can accelerate rather than hinder innovation, and a cultural emphasis on sustainability that’s becoming a source of competitive advantage rather than constraint.

The timing of this fund raise is particularly significant. As nations and corporations alike grapple with the dual challenges of maintaining economic growth while addressing climate imperatives, the technologies Voyager supports represent the convergence of these objectives. Energy software that optimises consumption reduces both costs and emissions. Advanced manufacturing that uses less material while producing higher-quality outputs addresses resource constraints while improving economics. AI systems that manage physical infrastructure create value through efficiency rather than just through new digital services.

What emerges from Voyager’s strategy is a vision of technological progress that’s more holistic than the typical Silicon Valley narrative. Rather than focusing solely on software or consumer applications, they’re investing in the physical infrastructure that underpins modern civilisation. This approach recognises that the next wave of innovation won’t be defined by incremental improvements to smartphones or social media algorithms, but by fundamental advances in how we generate power, move goods, build structures, and manage resources.

The scale of the fund—$475 million total across both funds—positions Voyager as a significant player in the European deep tech ecosystem. While not at the scale of the continent’s largest climate funds, it’s large enough to lead meaningful rounds and provide the patient capital that hardware-heavy, infrastructure-focused companies often require. This is particularly important in Europe, where the venture ecosystem has historically been more conservative than its American counterpart, especially when it comes to capital-intensive physical technologies.

As Voyager begins deploying Fund II, the broader implications for Europe’s technological sovereignty become clear. By backing companies that address critical dependencies—whether in energy, materials, or manufacturing—the firm is helping to build a more resilient economic foundation. In an era where technological leadership increasingly determines geopolitical influence, these investments could prove as strategically important as traditional infrastructure projects or defence spending.

The success of Voyager’s approach will ultimately be measured not just in financial returns, but in whether Europe can indeed establish leadership in the technologies that will define the 21st century economy. If they succeed, Fund II may be remembered not just as a significant venture capital raise, but as a catalyst for Europe’s emergence as a technological superpower in the domains that matter most for sustainable prosperity.
