Symbium

Symbium builds building and planning code directly into a browser, so a homeowner or contractor can see instantly what is allowed on a specific property and get a permit issued on the spot, with the regulatory checks already run. The technology is a logic-driven AI developed by the founding team at Stanford, applied to the least glamorous obstacle in decarbonization.

Electrifying the country's housing means retrofitting tens of millions of homes, and every one of those retrofits needs a permit from a jurisdiction with its own code, its own forms, and its own queue. Solar permits routinely take weeks. Multiply that across every panel, heat pump, and panel upgrade in the country and permitting becomes a genuine constraint on the energy transition, not a clerical annoyance. The hardware is ready. The paperwork is what's slow.
