Hemant has been at various times in his life, student, researcher, entrepreneur, venture capitalist and angel investor. After graduating from IIT-Mumbai in 1975, He worked at Tata Consultancy for sometime before going to US for higher studies. After getting MS from Case Western Reserve University and PhD in EE from Stanford University, He joined Bell Laboratories as a researcher working in the field of Computer networking and switching system. After getting bored by the inaction of AT&T in exploiting his research work for commercial gains, He decided to go out on his own to do just that. This effort, building a company in Computer networking space was quite timely and turned out to be a life changer for him. The company he founded, Torrent Networking Systems, built a next generation of fast Internet Routers. Ericsson acquired the company after merely three years of operations for $450M.
