Amphiform Raises $5.5M for Atomic Fuel Cells to Power AI & Space

OXFORD, United Kingdom – May 19, 2026 – Amphiform, a deep tech startup building energy materials from the atomic level up, has secured $5.5 million in a pre-seed funding round. The investment, led by General Catalyst and co-led by Main Object, is aimed at solving critical energy bottlenecks threatening to stall progress in artificial intelligence, space exploration, and national defense.

With participation from Embassy Ventures, K5/Tokyo Black, and notable angel investors including Hugging Face co-founder Thomas Wolf and investor Charlie Songhurst, the funding signals strong confidence in the company’s ambitious approach. Amphiform is not just improving existing fuel cells; it is redesigning them atom by atom to unlock what it claims is an order-of-magnitude leap in performance and cost-effectiveness.

“Energy is the bottleneck on every other ambition humanity has: to decarbonise, to compute, to explore,” said Grisha Sheldunov, Amphiform's 22-year-old founder and CEO. “The era of intelligent machines, electrified industry and expansion of life beyond Earth needs an energy source that none of today’s technologies can deliver: clean, abundant, dense enough to fly and cheap enough to scale.”

A New Kind of Matter, Atom by Atom

At the heart of Amphiform's mission is a fundamental critique of today's energy technology. Conventional fuel cells, while promising, are often heavy, expensive, and inefficient. The chemical reaction that generates electricity occurs only at a thin interface, leaving most of the costly catalyst material—often precious metals like platinum—unused and inert. This has long been a primary barrier to their widespread adoption.

Amphiform’s solution is to engineer what it calls a “new kind of matter.” Using advanced manufacturing techniques like atomic layer deposition (ALD), the company builds hybrid materials layer by atomic layer. This process turns the entire volume of the material into an active catalytic surface. Instead of a thin, inefficient interface, the fuel, catalyst, and electrons can interact throughout the structure, which is designed to be as lightweight and powerful as physically possible.

The company claims this breakthrough will result in fuel cells with up to 30 times higher power density than many current solutions. While a bold claim, it is rooted in established material science principles. Industry benchmarks for standard fuel cell systems often hover around 3-4 kilowatts per liter (kW/L). A 30-fold increase would place Amphiform’s technology in the 90-120 kW/L range, an ambitious but potentially achievable target for next-generation systems. Furthermore, the company projects its technology will be 85% cheaper. This cost reduction is largely driven by the ALD process, which research shows can drastically reduce the required amount of expensive platinum catalyst by up to 80-90% while maintaining or even enhancing performance.

Powering the Pillars of Modern Infrastructure

Amphiform is targeting sectors where the demand for dense, reliable power is most acute and where existing infrastructure is failing to keep pace. The first and most urgent market is AI data centers. The voracious energy appetite of AI models is creating an unprecedented strain on power grids, with data center build-outs frequently outpacing the availability of electricity.

“At Hugging Face, we have a front-row seat to the rising energy costs of AI models and robotics, and I’m excited to see such a talented team tackling this enormous challenge,” commented Thomas Wolf, co-founder of the influential AI company.

Beyond data centers, Amphiform’s technology addresses strategic needs in defense and space exploration. For defense, compact, powerful, and quiet energy sources that run on easily transportable liquid fuels could offer significant logistical and tactical advantages, reducing reliance on vulnerable fuel supply chains. In space, where every gram of mass is critical, a high-density power source could enable longer missions and more ambitious scientific payloads. By addressing these markets, the company aims to help rebuild a Western energy stack less dependent on volatile global oil markets and supply chains dominated by geopolitical rivals.

The Visionary and the Venture

The driving force behind this atomic-level engineering is founder Grisha Sheldunov. A National Chemistry Olympiad winner from Ukraine and a quantum chemistry postgraduate from the University of Oxford, Sheldunov's deep technical background is central to the company's identity and its investors' confidence.

“What stood out to us is Amphiform’s focus on solving power density constraints through new materials and how directly Grisha’s deep roots in chemistry map to it,” noted Yuri Sagalov, Managing Director at General Catalyst. “As demand from data centres, defence, and space pushes up against these limits, he has the depth and execution to go after it.”

Based in Oxford and San Francisco, Amphiform is charting a unique path. It is emerging as a founder-led company from the rich Oxford academic ecosystem, rather than pursuing a traditional university spin-out model. This independence allows it to move with the agility of a startup while leveraging the intellectual rigor of its environment. The company is now using its pre-seed capital to build out its research lab in Oxford and accelerate development.

The Fuel for the Future: Promise and Hurdles

A key element of Amphiform's strategy is its choice of fuel. By precisely tuning the atomic-scale structure of its materials, the company’s fuel cells are designed to run efficiently on energy-dense liquid fuels like methanol and ethanol. This approach sidesteps many of the storage and infrastructure challenges associated with compressed hydrogen gas.

Crucially, both methanol and ethanol can be produced as “green” fuels. They can be synthesized from sustainable biomass or, more futuristically, by combining captured carbon dioxide with green hydrogen produced from renewable electricity. This positions Amphiform's technology as a potential cornerstone of a circular carbon economy, turning a waste product (CO2) into a valuable fuel.

However, the path to supplying a global fleet of advanced fuel cells is not without its challenges. While the technology to produce green methanol and ethanol exists, scaling it to meet the massive demand of industries like data processing is a significant undertaking. The production of e-methanol, for instance, is heavily dependent on the availability of cheap, abundant green hydrogen, which itself is an industry in its nascent stages. The economic and logistical hurdles to creating a global supply chain for these renewable fuels are substantial, and Amphiform's success will be intrinsically linked to the maturation of this wider energy ecosystem.
