Cradle Bio vs Profluent Bio
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.
AI protein design company released OpenCRISPR-1, the first gene editor designed entirely by AI; raised $35M developing novel enzymes, antibodies, and gene-editing tools by exploring protein sequence space beyond what evolution has produced.
About
Profluent Bio is an AI protein design company founded in 2022 by former Meta AI researcher Ali Madani, raising $35M in seed and Series A funding. The company trains large generative models on biological sequence data to design novel proteins with specific structural and functional properties, analogous to how large language models generate text. Profluent made scientific history in 2024 by publishing OpenCRISPR-1, the first gene editor designed entirely by AI rather than adapted from natural organisms, which the company released open source for non-commercial research. The platform enables design of novel enzymes, antibodies, and gene-editing tools by exploring protein sequence space far beyond what evolution has produced. Profluent works with pharmaceutical and agricultural biotechnology companies that need custom protein tools for research and therapeutic development. The company represents a fundamental advance in moving protein engineering from directed evolution and rational design toward generative AI-driven discovery.
