Company Description

At Butterfly, we are building a device that will make medical imaging accessible to everyone in the world. We have reinvented ultrasound by integrating core components into a single silicon chip. The result is a high-performance imager that is more portable and less expensive than any other system in the world. The system's on-board Deep Learning Algorithms, trained by ultrasound experts, will guide clinicians with less expertise. It’s a breakthrough that will save millions of lives.

Our successes have been profiled in various media outlets including MIT Technology Review, IEEE Spectrum, Forbes, and WIRED Magazine. Butterfly Network, Inc. (a 4Catalyzer company) is privately-held and well-funded by a small group of extraordinarily successful serial entrepreneurs.
