About Halmos Labs

Halmos Labs rebuilds the drug development infrastructure around agents. To prove the future, we are aiming to have our AI be the first to bring a drug to market, and have already brought a cancer vaccine, and a new antibiotic, to the lab with results expected in mid December. Physical validation is the main bottleneck of scientific research agents. Existing labs already have capacity, yet experiments remain difficult to access and coordinate. Halmos Labs plans experiments, and enables access to physical validation. Connecting to Halmos, every agent can close the loop on R&D without leaving the terminal.
