# Flux

> Flux is a browser-based, AI-native hardware design platform that turns text prompts into manufacturable printed circuit boards. The San Francisco company calls its product an 'AI Hardware Engineer' and is rewriting how electronics get designed by combining an electronic CAD environment with an agentic copilot that researches parts, draws schematics, lays out boards, and prepares files for fabrication.

- **Founded:** 2019
- **Headquarters:** San Francisco, California, United States
- **Founders:** Matthias Wagner (Co-founder & CEO), Lance Cassidy (Co-founder), Christian Blank (Co-founder)
- **Team size:** ~110 employees
- **Products:** Flux, Flux Copilot, AI Hardware Engineer
