Turning Unused Home Power into a Controllable Resource with SPAN
from Inevitable · host Cody Simms, Arch Rao
Arch Rao is Founder and CEO of SPAN, the company behind the smart electrical panel that has expanded into utility grid management with SPAN Edge and distributed AI infrastructure with XFRA. What began as a smarter way to manage home electricity has evolved into a platform designed to digitize the electric grid, enable mass electrification, and unlock new AI compute capacity using existing residential infrastructure. In this episode of Inevitable, Rao explains why SPAN's vision has grown beyond the home electrical panel, how utilities are using software-defined power management to avoid expensive infrastructure upgrades, and why distributed AI inference could become a new class of digital utility. He also discusses the intersection of electrification, grid modernization, and AI demand, arguing that the next major energy transition is the digitization of the electric grid itself. Note: SPAN is an MCJ portfolio company Episode recorded on July 8, 2026 (Published on August 4, 2026).
