THE PROMISE With ultrasound a doctor can see into the heart of someone in cardiac arrest or into the abdomen of a woman with an ectopic pregnancy, and save their lives. 75 years after its invention, ultrasound remains an indispensable tool for diagnosis and monitoring. THE PROBLEM 60% of the world lacks access to medical imaging because current technologies are unwieldy, expensive, and require extensive training. While doctors carry supercomputers in their pockets, they still rely on the 200-year old stethoscope​ as their primary diagnostic tool. THE SOLUTION Our mission is to democratize healthcare by making medical imaging accessible to everyone around the world. Butterfly Network has raised >$350M to develop and commercialize a handheld, smartphone-connected ultrasound probe powered by AI. We operate at the intersection of medicine, engineering, and machine learning to create breakthrough technology that becomes smarter with each new patient.
