Casey Spencer is Co-Founder and CEO at Voxel Energy, a Y Combinator Winter 2026 company building energy-independent data centers powered by solar and repurposed EV batteries.

Casey was Project Manager for Tesla's Infotainment and Autopilot team, where he oversaw prototype hardware distribution and played a key role in Tesla's production ramp in 2018. He has since founded three hardware companies and co-founded ItsWare.

Casey is an award-winning engineer who personifies the phrase Jack of all trades, with experience spanning managerial, product, and engineering roles. He attended Make School and has built projects ranging from mind-controlled Tesla vehicles to drone construction.

Voxel Energy was founded in 2025 by ex-Tesla serial entrepreneurs who spent the last decade defining the future of American energy consumption. The company is deploying off-grid data centers that bypass utility connection delays using solar energy, second-life EV batteries, and novel DC microgrid architecture.

Voxel Energy is addressing the AI power bottleneck by reducing data center time-to-power from five years to months. The company has hundreds of acres under contract and a live operational prototype already running off-grid compute.
