About
Today, the biggest bottleneck in genetic medicine isn’t the power of mRNA, CRISPR, or gene therapy—it’s that we can’t get these medicines anywhere but the liver. Our RAPTOR™ platform is the first AI-driven system that makes extrahepatic genetic medicine scalable. Unlike the slow, inefficient trial-and-error process that dominates biotech, we directly test hundreds of novel lipid nanoparticles (LNPs) in non-human primates (NHPs) at 100 times lower cost, generating real-world, human-relevant data.
