## Summary

Dr. Gregory Charvat, CTO of Humatics Corporation, discusses his three startups: Butterfly Network, Hyperfine, and Humatics. He details the pivot at Butterfly Network from high-cost ultrasound tomography to a handheld ultrasound on a chip using MEMS technology. He also describes Humatics' development of a short-range, high-precision indoor GPS system for factory automation, which achieved centimeter and millimeter accuracy through time-of-flight measurements.
