Butterfly Network, Inc.
A maker of handheld ultrasound devices that plug into a smartphone, Butterfly Network builds its whole-body imaging probes around a semiconductor chip rather than traditional lead-based crystals. Its products include the Butterfly iQ3, iQ+, and Butterfly Move, used by doctors, vets, and health systems. Founded in 2011 by DNA-sequencing pioneer Jonathan Rothberg, the company got its name partly from the butterfly-shaped signal-processing networks his team studied. Its compact probes are famously small enough to fit in a coat pocket.
