AI-Powered Custom Circuit Boards Designer and Developer Diode Raised $11.4 Million in Series A

Diode Computers, a company that helps hardware companies automate the design and development of PCBs, led by Davide Asnaghi(Co-Founder and CEO) and Lenny Khazan(Co-Founder and CTO), raised $11.4 million in Series A led by Andreessen Horowitz, alongside Y Combinator, to scale Diode’s compiler and onboard more fabs.

Diode is redesigning Electronic Design Automation to work better for both humans and machines. Its open-source, Pythonic code is easily readable by large language models and humans alike, while a Rust-based core enables lightning-fast design verification. Unlike traditional tools, Diode incorporates shop-specific, machine-readable constraints from the start, making designs more accurate and manufacturing-ready. Built on the foundation of KiCad, Diode advances open-source EDA as a proud Platinum Sponsor.

Diode enables a new pace of hardware development—one board design every four days. A single electrical engineer shipped over 100 unique designs in a year with minimal overhead. Teams at Physical Intelligence, Saronic, and multiple Fortune 100 companies are using Diode to cut revision cycles from five to one. The platform delivers format-agnostic outputs—BRDs, ODB++, IPC-2581—regardless of whether the current workflow is based in Altium or Cadence. Each design processed through Diode fuels a continuous feedback loop, incorporating real-world yield data, stack-up variations, lead times, and reflow profiles, making the compiler smarter and future designs more robust.
