JITX is a Berkeley- and San Jose-based software company building a code-driven, AI-assisted platform for circuit board design. Instead of dragging parts around a canvas by hand, electrical engineers describe what a board must do in code, and JITX selects components, places parts, routes traces, and checks the design against electrical, mechanical, and manufacturing rules. Spun out of UC Berkeley and backed by Y Combinator and Sequoia Capital, the company is used by hardware teams at firms like Honeywell Aerospace, Lockheed Martin, Northrop Grumman, OpenAI, and HP, who report 5-20x productivity gains on complex multi-layer designs.
Sergiy Nesterenko is the founder and CEO of Quilter, a Los Angeles company building AI that designs printed circuit boards on its own. A former SpaceX avionics engineer who spent five years on Falcon 9 and Falcon Heavy electronics, he watched one of his first boards literally burn up in his hands and decided manual PCB layout was a problem worth a decade. Quilter trains its system on physics and constraints rather than copying human designers, and in 2025 it produced the world's first fully functional computer laid out by AI.
