Periodic Labs

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

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.

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.

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