## About Quilter

## Company Overview
- **One-liner**: Quilter is a physics-driven AI that automates PCB placement and routing, enabling electronics design teams to generate board layouts in hours instead of months.
- **Entity Type**: Private (Series B)
- **Headquarters**: Los Angeles, California, United States
- **Founded**: 2019
- **Founders**: Sergiy Nesterenko

## Core Business
- **Primary industry**: Electronic Design Automation (EDA) / AI for Hardware Design
- **Target customers**: Hardware engineering teams in consumer electronics, aerospace, defense, and regulated industries (B2B, Enterprise)
- **Mission or purpose statement**: Quilter exists so engineers spend their time inventing—not dragging traces at 2AM. The company aims to make PCB layout as plentiful and iterative as software builds, powering a new paradigm called Hardware-Rich Development™.

## Products & Services
- **Quilter AI (Physics-Driven PCB Layout Engine)**: An autonomous design agent that takes in schematics and constraints (from Altium, Cadence, Siemens, KiCAD) and outputs complete, manufacturable board layouts. Uses reinforcement learning trained on physics simulations (Maxwell’s equations, thermodynamics, manufacturing constraints), not on customer data. Returns files in the same format as submitted.
- **Self-Hosted / On-Premise Deployment**: Available for organizations with strict IP protection needs (aerospace, defense, ITAR compliance). Deploys into a customer’s own Kubernetes cluster as a Helm chart, with GPU requirements (NVIDIA GPUs, 16 GB VRAM).
- **Free Tier & Startup Program**: A free tier launched in August 2025 to give early-stage hardware startups access to the platform, plus a dedicated Startup Program.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total Funding — $35.0M (Series A: $10M led by Benchmark in Feb 2024; Series B: $25M led by Index Ventures in Apr 2025)
- **Notable Investors/Partners**: Benchmark (Eric Vishria joins Board), Index Ventures (Nina Achadjian joins Board)
- **Growth Signals**: 100k+ designs generated since Open Beta launch (Feb 2024). Headcount grew 50% YoY (19 employees). Team includes alumni from SpaceX, Apple, NASA, Johns Hopkins APL, MIT, Cadence, and Synopsys.

## Competitive Advantages
- **Physics-First AI, Not Human Data**: Trained via self-play against physics simulations (like AlphaGo), not on proprietary customer designs — a core privacy promise and technical moat. No training on paying customer data.
- **Autonomous End-to-End Layout**: Generates complete, manufacturable boards from schematics and constraints, reducing weeks of manual work to hours. Supports 100–1,000 components per board.
- **Transparent Design Review**: Provides clear feedback on which design aspects are “done” and which need further review, with continuous physics verification (DDR length matching, impedance control, clearances).
- **IP Protection & Compliance**: SOC 2 Type II certified, data encrypted at rest and in transit (TLS 1.3, AES-256). On-premise deployment option for the most sensitive environments.

## Strategic Focus
- **Expanding Capabilities**: Actively developing blind/buried vias, BGA fanout (in beta), length matching, and RF net handling. The “goldilocks zone” of supported board complexity is expanding with every release.
- **Hardware-Rich Development™**: Driving a paradigm where multiple board iterations can be run in parallel overnight, compressing delivery timelines from 4–8 weeks to days, and enabling 2–3 iterations in the time one used to take.
- **Market Adoption**: Targeting regulated industries (aerospace, defense, consumer electronics) with on-premise and GovCloud deployment options. Free tier and startup program to build developer mindshare early.

## Why Work Here
- **Talent & Culture**: Team built from SpaceX, Apple, NASA, Johns Hopkins APL, MIT, Cadence, Synopsys, and even operators from the 75th Rangers. Described as “first-principles engineering, a high bar, and respect for designers.”
- **Mission-Driven**: A chance to solve a real bottleneck in hardware engineering — turning months of layout work into minutes. The company believes “in five years, manual PCB design will feel like compiling code by hand.”
- **Engineering Focus**: Technical roles dominate (12 of 19 employees). Open positions include Senior/Staff Software Engineer (C++). The company is hiring for deep AI and systems engineering talent.
- **Work Environment**: Not explicitly stated, but the remote-friendly nature of the team (presence in US, India, Canada, Ireland) and the on-premise product suggest a flexible, engineering-driven culture.
