SPAN builds AI-powered smart electrical panels and home energy management software, applying machine learning and connected-device technology to a category that has changed little in a century. The company's flagship SPAN Panel replaces the traditional electrical panel with a connected device that lets homeowners monitor and control individual circuits from a smartphone, optimise energy consumption, and integrate solar, battery storage and EV charging. The product line is rounded out by SPAN Drive, an EV charging product, and the SPAN Home App, an application for monitoring and managing household energy use.
For engineers and researchers, the technical work spans AI-powered energy management, IoT and smartphone-connected hardware, embedded systems for real-time circuit-level monitoring, and integration across solar, storage and EV charging. The stated goal is to electrify 10m homes by 2030 and to remove millions of tons of CO2 emissions annually, framing the work at the intersection of software, hardware and the decarbonisation of the built environment.
Founded in 2018 by Arch Rao, formerly head of Tesla's Powerwall programme, SPAN has grown to 201-500 employees. The company lists partnerships with Eaton, Kenmore, Carrier and Tesla, and describes its mission as enabling electrification for all while decarbonising the built environment.
