OnMobile is incubated by Infosys. It is a product company with cutting edge R&D in wireless space. Their technology handles over 3500 million calls and has a reach of about 260+ million telecom subscribers.
Had you invested in IPO of OnMobile, two months ago, you would be a rich person by now (when the whole market fell, their stock gained). Needless to say existing employees made a windfall thru IPO.
So if you want to work on cutting edge and scalable solutions, look no further.
