In the high-stakes world of infectious disease, the clock is always ticking. Karius isn't just testing for pathogens; they're decoding the invisible battlefield of the human microbiome. While traditional diagnostics take days to guess at specific bacteria, Karius uses liquid biopsy and NGS to scan for thousands of microbes simultaneously—turning a 7-day diagnostic process into a single test.

"Karius isn't selling a test; they're selling certainty in the face of sepsis."

The company's approach to funding is aggressive. With $254M in the bank against $46M in revenue, they are in a 'land grab' phase, prioritizing market penetration over profitability. This capital efficiency ratio (5.5x funding to revenue) indicates investors believe the Total Addressable Market (TAM) for sepsis and immunocompromised patient diagnostics is massive and largely untapped.

• Liquid Biopsy for Infection: They treat blood like a liquid biopsy, extracting microbial DNA to find pathogens hiding in plain sight.
• Unbiased Metagenomics: Unlike PCR, which looks for specific suspects, Karius casts a net over all microbial DNA, catching the unexpected.
• Scalable Infrastructure: The ability to process thousands of samples via NGS requires massive computational and logistics infrastructure—a moat few competitors can match.
