Remote Investor

Title: Investor Relations

Reporting Structure: CFO

Our client is an El Segundo, CA-based startup building the world's first mass-produced, portable nuclear microreactors. The company's first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases.

Our client's unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials.

On track to test its first reactor at the Idaho National Laboratory

Initial customer deliveries beginning in 2028

Raised $575M+ to date - including a new strategic investment from Lockheed Martin Ventures
