Founded in 2019 by Sergiy Nesterenko, a former SpaceX engineer, Quilter pioneers fully autonomous AI PCB design through physics-driven reinforcement learning. Quilter is transforming hardware development into a continuous, agile process by automating placement, routing, and verification to deliver completed designs in minutes, rather than weeks. Quilter integrates with Altium, Cadence, and Siemens Xpedition, runs natively on private cloud and GovCloud with on-premise deployment available for sensitive environments, and is currently under observation for SOC 2 Type II compliance. Quilter has raised $40 million to date from Index Ventures, Benchmark, Coatue, Root Ventures, and industry experts like Lip-Bu Tan, among others.
