Dan Cook
Dan Cook is the CEO, Co-founder, and Investor at Lyten Inc, a San Jose-based deep-tech company pioneering 3D Graphene supermaterial and next-generation lithium-sulfur batteries. With over three decades spanning General Motors, NeXT Computer (under Steve Jobs), Bay Networks/Nortel, and private equity at Cerberus Capital, Cook pivoted to found Lyten in 2015 around a serendipitous discovery: trying to turn methane into clean hydrogen, the team accidentally created a revolutionary 3D graphene material. Under his leadership, Lyten has raised over $1.2 billion, shipped lithium-sulfur A-samples to automotive and military customers, announced the world's first lithium-sulfur gigafactory in Reno, Nevada, and in 2025-2026 acquired significant Northvolt assets across Europe to become one of the largest battery manufacturers on the continent.
Lyten
Lyten is a San Jose-based supermaterials company building lithium-sulfur batteries, advanced composites, and sensors on top of its proprietary 3D Graphene platform. Founded in 2015, Lyten makes its 3D Graphene by cracking methane into nanostructured carbon, then uses that material to produce lighter, higher-energy batteries with a domestic, non-conflict supply chain. The company is scaling production from a San Jose pilot line toward a multi-gigawatt-hour gigafactory in Reno, Nevada and a newly acquired European footprint.
