What Neutron Power Ventures does

Neutron Power Ventures (NPV) is a US-based, specialist nuclear energy venture capital firm founded in 2025 by Andrew Meehan. The firm backs Series A+ companies across the full nuclear value chain — reactors, fuel cycle, developers, and enabling technologies — through a direct-investment and co-invest SPV structure. Its current portfolio comprises three SPV-backed companies: Copenhagen Atomics (Danish thorium-fueled molten salt reactors for factory production), Aalo Atomics (factory-built modular reactors targeting AI data-center power demand), and Radiant Nuclear (helium-cooled TRISO-fueled reactors for military and remote deployment), plus one co-invest.

The firm’s investment thesis is built on a technoeconomic lens (commercial viability over academic novelty), a "both/and" stance that funds both water-cooled and advanced reactors, and a "full capital stack" approach that maps the financial, political, regulatory, and stakeholder relationships nuclear projects require. NPV positions itself as industry-native, claiming direct relationships with operators, regulators, and national labs including Oak Ridge and the Paul Scherrer Institute, and asserts visibility into nuclear deals months before public announcement. Fuel cycle infrastructure and enabling technologies (grid, thermal storage, deployment enablers) are flagged as durable, under-deployed layers of the value chain.

The business model is conventional emerging-manager venture economics: revenue is generated through management fees on SPVs and carried interest on successful exits. Pricing (fund terms, fee schedules) is not publicly disclosed and is negotiated with portfolio companies and LPs directly. The firm is led by a sole general partner — Andrew Meehan, a Columbia-trained chemical engineer who previously spent six years at Celgene and Bristol-Myers Squibb scaling CAR-T cell therapy manufacturing before returning to energy — and operates with a small team (1–10 employees). As of early 2026, the firm has recorded several portfolio-company milestones, including Aalo Atomics’ DOE microreactor program selection (February 2026), Radiant Nuclear’s portable reactor prototype progress (January 2026), and Copenhagen Atomics’ manufacturing milestone (March 2026).

Direct peers

• Azolla Ventures: Early-stage venture firm explicitly focused on advanced nuclear fission, fusion, and enabling technologies. Highly comparable to NPV in mandate, stage focus, and nuclear-specialist positioning, making it the closest direct peer.
• Lowercarbon Capital: Thematic climate-tech VC backing companies working on decarbonization, with explicit exposure to nuclear energy investments. Comparable as a thematic, mission-driven fund that backs frontier clean energy including nuclear alongside other decarbonization bets.
• Prelude Ventures: Early- and growth-stage clean energy and sustainability venture firm investing across advanced energy, mobility, and resource technologies. Comparable as a specialist clean energy fund overlapping with NPV on enabling technologies and fuel-cycle adjacencies.
• Congruent Ventures: Early-stage climate-tech fund backing companies in energy, mobility, and the built environment. Comparable as a thematic clean energy venture firm with overlap on grid, storage, and advanced energy bets adjacent to NPV's portfolio.

Broad incumbents

• Breakthrough Energy Ventures: Multi-billion-dollar climate-tech fund backed by Bill Gates and allied investors, investing across nuclear, storage, and other decarbonization technologies. Comparable as a deep-pocketed climate VC that competes for the same nuclear deal flow from a much larger base.
• DCVC: Deep-tech VC investing in computational, materials, and energy breakthroughs, including nuclear and grid technologies. Comparable as a deep-tech investor overlapping NPV on reactor and enabling technology bets from a larger, more generalist platform.
• Khosla Ventures: Large, deep-tech-leaning venture firm with a long-standing clean energy practice and nuclear exposure. Comparable as a deep-pocketed incumbent that competes for the same frontier nuclear companies at later stages and from a more diversified portfolio.
• Lux Capital: Sector-agnostic deep-tech VC with active investments in fusion, advanced reactors, and energy infrastructure. Comparable as a deep-tech fund that intersects with NPV on nuclear bets while operating across a much broader portfolio.
• Energy Impact Partners: Global utility- and corporate-backed VC and growth platform investing across the energy transition, including nuclear-adjacent technologies. Comparable as an energy-focused investor that competes for the same nuclear and grid enabling-technology deal flow.

Emerging players

• Engine Ventures: Deep-tech venture platform investing at the intersection of compute, materials, and energy, with relevant exposure to nuclear and enabling technologies. Comparable as a deep-tech platform that occasionally competes for nuclear-adjacent companies from a broader mandate.
