Cascade #32 – Jason Eichenholz: Moving Data at the Speed of Light to Unlock the Future of AI and Energy
Jason Eichenholz is the founder and CEO of Relativity Networks, a company radically reimagining the physical infrastructure behind AI by enabling data to travel at the speed of light in air.
Jason's story begins with a laser beam in a high school physics lab. That spark launched a lifelong obsession with photonics, earning him a PhD in laser physics and eventually leading to Luminar.
He helped take the company from two people in a garage to a billion dollar plus public company powering next gen autonomous vehicles.
After stepping back from Luminar he thought he was done with startups until a Hollow Core Fiber prototype landed in his inbox. The physics checked out, the market was undeniable and the bottleneck was existential.
Latency is now a power problem. Relativity Networks was born.
Today, Jason is building a fiber network that literally moves light faster, shrinking digital distances between data centers and unlocking new possibilities for AI, climate tech, 5G and more.
We talked about building Luminar from scratch, leading through others, his work at Jonathan's landing, and how Relativity gives hyperscalers the freedom to put data centers where the power is, not where latency says they have to.
