Pilgrim raises $25M seed at $150M for airborne biothreat sensor

Pilgrim's Argus device "combines air sampling and genomic sequencing to detect biological threats," according to the Wall Street Journal, and the company has just closed a $25 million seed round at a $150 million valuation. Buckley Ventures led; two Anthropic leaders, Frontier Red Team head Logan Graham and technical staff member Sholto Douglas, joined the round, alongside Peter Thiel and Coinbase co-founder Fred Ehrsam.

The 50-pound device is designed to catch airborne pathogens including Ebola and anthrax. Pilgrim has signed an agreement with the US Centers for Disease Control and Prevention to produce an automated airborne biosurveillance system, and has already begun deploying Argus units across the country.

The unusual detail is where the personal capital is coming from. Anthropic's Frontier Red Team is the internal group that probes what frontier models could enable in domains like biology; two of its senior figures now hold personal stakes in a company selling early-warning hardware for exactly that class of threat. It fits a broader Anthropic-adjacent thread visible this week, including Basecamp Research's $140M Series C, which Anthropic joined as a corporate investor.

The reporting does not disclose the size of the CDC contract, how many Argus units have shipped, or where they are installed.
