# Quilter

> Quilter is a Los Angeles-based company building the first fully autonomous, physics-driven AI for printed circuit board (PCB) layout. Founded in 2019 by former SpaceX avionics engineer Sergiy Nesterenko, Quilter trains reinforcement-learning agents on the laws of physics - not human design patterns - to place components, route traces, and physics-validate complete board designs in hours instead of weeks. The company positions itself as the 'compiler for hardware,' aiming to make manual PCB layout as obsolete as hand-compiling code.

- **Founded:** 2019
- **Headquarters:** Los Angeles, California, United States
- **Founders:** Sergiy Nesterenko (Founder & CEO)
- **Team size:** ~46 employees (LinkedIn/Apollo estimate); team includes alumni of SpaceX, Apple, NASA, Johns Hopkins APL, MIT, Cadence and Synopsys
- **Products:** Quilter autonomous PCB layout platform, Free tier, Project Speedrun
- **Notable:** First company to publicly demonstrate fully autonomous, physics-driven PCB layout (placement, routing and validation)., Project Speedrun: autonomously designed and verified a working computer in under a week., Quilter-designed boards manufactured, tested and used in production - including in orbit.

## Products & services

- **Quilter autonomous PCB layout platform** — A physics-driven AI system that performs complete PCB layout - component placement, trace routing, and physics validation - autonomously. Reinforcement-learning agents generate dozens of candidate layouts in parallel, enforcing differential pairs, DDR timing, clearances and manufacturing constraints during generation, and produce fab-ready designs in hours.
- **Free tier** — A free tier launched August 2025 offering fully autonomous PCB layout with unlimited iterations for engineers and smaller teams to try the platform.
- **Project Speedrun** — A demonstration in which an engineer used Quilter's AI to autonomously design and verify a working NXP i.MX 8M Mini-based computer in under one week - billed as the first computer designed by AI.

## Achievements

- First company to publicly demonstrate fully autonomous, physics-driven PCB layout (placement, routing and validation).
- Project Speedrun: autonomously designed and verified a working computer in under a week.
- Quilter-designed boards manufactured, tested and used in production - including in orbit.
- Raised $40M total from top-tier investors including Index Ventures, Benchmark, Coatue and Root Ventures.
- Cut backplane/interconnect board layout from 30+ days to under 24 hours in customer use cases.

## Latest updates

- **2025-10** — Closed a $25M Series B led by Index Ventures, bringing total funding to roughly $40M; Index's Nina Achadjian joined the board.
- **2025-08** — Launched a free tier offering autonomous PCB layout with unlimited iterations.
- **2024-02** — Launched open beta of the autonomous PCB layout platform.
