About

Quilter develops physics-driven AI software that automates PCB placement and routing, reducing layout cycles from weeks to hours. Using reinforcement learning trained on millions of synthetic boards against the laws of physics, the platform generates hundreds of fabrication-ready candidate designs, validates every trace against physical constraints, and returns files in native ECAD formats including Altium, Cadence, Siemens, and KiCAD. Quilter handles boards with 100 to 1,000 components, automated BGA fanouts, impedance-controlled nets, and differential pairs, serving industries such as semiconductors, robotics, consumer electronics, and aerospace and defense. The platform enables teams to scale without hiring, compress delivery timelines from 4-8 weeks to days, and iterate on multiple stack-ups and form factors in parallel. Founded in 2019 and headquartered in Los Angeles, California, Quilter has raised $35M in Series B funding from investors including Benchmark, Coatue, Root Ventures, Harrison Metal, and Index Ventures.
