Lets just take India for an example a huge market lets look at Nimbuzz ranked 11,151 in traffic, We chat ranked8963 ,viber 7615,whatsapp 431 and compare them to mig33 ranked 68344. Now mig33 is the little brother to these big boys but when you consider whatsapp has been taken out by facebook for 19 billion and has only ever raised 8 million in venture capital not a bad return and viber was taken out by Japanese membership-based Internet services company Rakuten for $900 million well you get my drift mig33 fully diluted still looks pretty good value imo.
Now in every story iv read these are the companys that get mentioned as the main competitors Line, WeChat, Hike, Rocketalk, Mig33, Imsy, Gupshup Messenger, JaxtrSMS, ChatON (Samsung), Pinch (Affle), among others, and maybe even Blackberry’s BBM service.
