The proof of concept for the device came out of collaboration between Sailesh’s former group at Microsoft Research, and David’s lab at Washington University at St. Louis. It generated a tremendous amount of excitement in the medical community as a potential successor to the “stethoscope”, but one that is a lot more powerful. Whenever medical professionals saw a demo of the device, they wanted to buy it. Since it is hard to sell a research prototype, Sailesh and David decided to incorporate Mobisante in December 2009 to create a commercial product based on the original idea.
