Periodic Labs
Periodic Labs is an AI Materials Discovery company founded in 2025 and based in San Francisco, United States. It has raised $300M in total funding, most recently a Seed in 2025.
Periodic Labs emerged from stealth in October 2025 with a $300M seed round led by Andreessen Horowitz, one of the largest seed rounds on record. Co-founded by Liam Fedus (former OpenAI VP of research and ChatGPT co-creator) and Ekin Dogus Cubuk (former Google DeepMind materials lead and a GNoME co-author), the company couples large AI models that form hypotheses and plan syntheses with robotic labs that run experiments autonomously, generating proprietary experimental data. Its initial targets are higher-temperature superconductors and industrial problems such as chip heat dissipation. Backers also include Felicis, DST Global, Accel, Nvidia's NVentures, and angels including Jeff Bezos, Eric Schmidt, and Jeff Dean.
Periodic Labs is the highest-profile bet that ex-frontier-lab AI researchers can automate the physical-science discovery loop, with the capital and pedigree to attempt it at scale.
