> Arch Rao is the Founder and CEO of SPAN, a San Francisco-based clean energy hardware company that reinvented the home electrical panel. A Stanford-trained mechanical engineer and former Tesla Energy leader who helped launch Powerwall, Powerpack, and SolarCity products, Rao founded SPAN in 2018 with a singular mission: rapidly decarbonize American homes by making the century-old electrical panel smart. SPAN's intelligent panels enable circuit-level control, real-time energy monitoring, solar and battery integration, and grid demand response - turning a neglected utility box into the command center for home electrification. With over $522M in total funding and backing from Wellington Management, Fifth Wall, Robert Downey Jr.'s FootPrint Coalition, and Amazon's Alexa Fund, SPAN is building the grid-edge infrastructure layer for the coming decades of home electrification.
