Aether Biomachines is an American artificial intelligence company that discovers proteins with high-impact, real-world applications. At the core of its work is a Protein Function Model that can unlock new proteins for novel functions. Aether’s AI is being built on an entirely proprietary dataset developed in-house through advanced high-throughput screening and innovative assay technology. Using this platform, Aether has developed seven new classes of proteins with capabilities ranging from refining metals at lower cost and breaking down persistent “forever chemicals” to producing industry-leading materials, enabling complex pharmaceutical manufacturing, recycling plastics, and capturing carbon dioxide. Aether is already translating its AI breakthroughs into practice, commercializing high-performance materials that can print ten times faster than current industry benchmarks while offering superior strength for the defense and aerospace industries.
