Company

Overview

$900M

Series A Investment

The company secured over $900 million in Series A funding led by top-tier investors.

135k ft²

Facility Size

Construction is underway in a 135,000-square-foot facility in San Leandro.

150 Modules

Fusion Target

They aim to use 150 modular units to achieve net facility gain by 2030.

Led by founders from NASA, DOE labs, and genomics—Eric Lander (co‑founder/CEO) and Keith LeChien (CTO) steer the technical vision.
They’re pioneering pulsed magnetic inertial fusion: stacking modular ‘bricks’ in Marx generators to drive fuel capsules to fusion.
Built in a 135k ft² San Leandro facility, the team of ~60 engineers and scientists is constructing full-scale pulser modules.
Collaborations with General Atomics and US national labs accelerate scaling and prototype testing.
Their demonstration system in Livermore targets research-grade operations ahead of commercial rollouts.
By focusing on mass‑manufacturable modules and affordable supply chains, they aim to bring fusion to market within a decade.

Culture + Values

Talented, humble builders
United by a shared sense of urgency — to meet rapidly growing global energy demand while addressing climate change
Shared sense of responsibility — to each other, to our investors, to our country, and to our planet
Committed to collaborating with the broader scientific community… regularly share and publish our research… committed to partnering with communities, regulators, policymakers, suppliers, industry peers, and customers

Environment + Sustainability

$900M+ Funded

Series A Financing

Raised $900 million in Series A funding tied to technical milestones for advancing clean energy solutions.

>100 MJ Output

Fusion Energy Yield

Collaborating with partners to achieve high-yield fusion energy output in inherently safe, carbon-free systems.

2030 Target

Net Facility Gain

Technology aims to achieve net facility gain by 2030, producing more fusion energy output than stored energy input.

Mission: power the world with abundant, affordable, clean energy
Building pulsed magnetic inertial fusion system using widely available materials and mass‑manufacturable modular units ('bricks' and 'modules') to support scalable clean power
Collaborating with National Lab partners (General Atomics, LLNL) to drive advances toward high‑yield fusion in inherently safe, carbon‑free systems
