Cradle Bio vs Karius
Side-by-side comparison of AI visibility scores, market position, and capabilities
Cradle provides an AI platform for protein engineering that accelerates the design of improved enzymes, antibodies, and other biologics for industrial and therapeutic use.
About
Cradle Bio is an AI protein engineering company founded in 2021 in Amsterdam, having raised $73M to build an AI-powered protein design platform. The platform combines generative AI with wet-lab experimentation to accelerate the iterative process of engineering proteins with improved stability, activity, and manufacturability. Cradle's technology enables researchers to design thousands of protein variants computationally and prioritize those most likely to succeed in laboratory validation, compressing protein engineering timelines from years to months. The company serves both industrial biotechnology customers engineering enzymes for biomanufacturing and pharmaceutical companies developing next-generation antibody therapeutics. Cradle partners with contract research organizations and biopharmaceutical companies to integrate AI-assisted protein design into existing discovery workflows. The company has been recognized as a leader in the European deep tech ecosystem and positions protein engineering AI as enabling a new era of designed biologics for medicine and sustainable manufacturing.
Karius raised $409M total including a $100M Series C in May 2024; its genomic blood test detects 1,000+ pathogens at 400+ U.S. hospitals; launched Karius Focus BAL for pneumonia in April 2025.
About
Karius is a Redwood City, CA-based life sciences company founded in 2014 that developed the Karius Test — a single blood draw that uses next-generation sequencing and AI to detect over 1,000 pathogens (bacteria, fungi, viruses, parasites) in seriously ill patients. The test is used when conventional cultures and targeted diagnostics fail, providing clinicians at transplant centers, children''s hospitals, and ICUs with a comprehensive pathogen report within 24 hours.
