Investment Thesis

🔥 The Problem

Scientific discovery is bottlenecked by slow, manual experimentation. Researchers spend months running experiments that could be automated.

🛠️ The Fix

Periodic Labs builds AI scientists paired with autonomous laboratories. Their AI models hypothesize, design experiments, and iterate at speeds impossible for human researchers, particularly in materials science.

Why Now

Foundation models have reached the capability level needed to reason about physical science, and lab automation hardware is mature enough to close the loop between hypothesis and experiment.

The Proof

Raised a record $300M seed round at ~$1.3B valuation. In talks for follow-on at ~$7B valuation within 6 months of launch.

👥 The Team

Liam Fedus (CEO, former VP of Research at OpenAI, key architect of ChatGPT) and Ekin Dogus Cubuk (former Google DeepMind scientist).
