Good product companies in India using Ruby/Rails?

Hi All,

I am trying to find out what all companies in India/Bangalore use
Ruby/Rails as their platform, shouldn’t these companies come forward to
take active part in organizing events like RubyConfIndia ?

List of product companies that I know are , please add to this list if
you know some company:

4.) Subex
5.) Citrix

Also, It would be great to see some reviews about the companies from the members.

Best Wishes,
