Indian-origin entrepreneurs in the US continue to make their mark in Silicon Valley, with three start-ups founded by people from India being named by a Fortune group magazine in a list of 15 innovations that have the potential to change the world of technology.

The three — Bloom Energy, Expensr and Vanu — have been featured in “The Next Disruptors — 15 companies that will change the world” list of Business 2.0, magazine published by CNN-Time Warner Group. The common thread between the three is that all of them have an Indian-origin US national as founder.

Bloom Energy is a utility company that aims to help households generate their own electricity; Expensr is a financial planning software solution provider; and Vanu is a radio wireless software solution that enables a base station to simultaneously operate through various platforms like GSM and CDMA.

While Vanu Inc has been founded by NRI CEO Vanu Bose, Bloom Energy is the brain child of K R Sridhar. Expensr, San Francisco-based startup that has developed software aimed at helping people fast and easy way to track their spending habits, has been co-founded by Indian-origin Shawn Gupta with fellow programmer Reman Child.

Sridhar, was professor of aerospace and mechanical engineering and director of Space Technologies Laboratory at the University of Arizona. He also served as an advisor to NASA. Other startups include PatientsLikeMe, an online community where patients discuss and track medical conditions; Blinkx, Web video search and advertisement insertion, and Zipcar that supplies self-serve hourly car rental in neighbourhoods.
