Wayfinder Bio is last week's Killer of the Week, and won because they have been cranking through pilots and closing deals with investors and customers alike. When GFP came onto the scene, it changed cell biology completely. Scientists could now see the actin cytoskeleton move in real time, and find where new cellular elements are localizing between different organelles. Now, with the ability not only to detect molecules, but also functionalize therapeutics, with their RNA aptamers, Wayfinder is enabling a new era of biology with their computational engine.
