PathSpot
PathSpot is a New York-based health and safety company for the food service industry. Its flagship HandScanner uses visible-light fluorescence spectroscopy to detect invisible contaminants on employees' hands in about two seconds, flagging the molecules that carry norovirus, E. coli, Salmonella, Listeria and Hepatitis A. Around that scanner the company built SafetySuite, a connected hardware-and-software platform covering temperature logging, digital task lists and food labeling. PathSpot operates in more than 10,000 food service locations worldwide.

Christine Schindler is the co-founder and CEO of PathSpot, the maker of the HandScanner - a device that mounts beside a kitchen sink, scans a worker's just-washed hands with light, and flags invisible contamination in seconds. A Duke-trained biomedical engineer who first built low-cost medical tools near Mount Kilimanjaro, she prototyped PathSpot's algorithms in her apartment bathroom, sold her car to fund it, and grew the company into a food-safety operating system used across the restaurant industry. She is a Forbes 30 Under 30 honoree, a Time Best Invention recognizee, and the founder of the nonprofit Girls Engineering Change.
