VCCircle has a 2-minute interview with Sanjeev Bikhchandani, Managing Director of Info Edge Ltd. According to the article, Info Edge is India's richest internet company. See: 2 Minutes With Sanjeev Bikhchandani: Rs 300 Crore & Counting | VCCircle

Info Edge owns a number of web portals including Jeevansathi.com, Naukri.com, Shiksha.com, Brijj.com and 99acres.com.

I notice that Info Edge don't seem to use the .IN extension much. For example, Jeevansathi.in redirects to Jeevansathi.com, even though it is an Indian matrimonial site. Also, Info Edge only uses 99acres.com, even though they own 99acres.in and the site mainly relates to real estate in India (although it does have some worldwide real estate listings).
