Headquartered in Singapore, nanu has more than 2.7 million downloads, of which more than 1.7 million originate in India.
nanu's ultra-low bandwidth technology enables it to consume 80% less bandwidth than similar VoIP apps. As a result, users are able to enjoy clear calls even on 2G or congested networks.
This, coupled with unlimited nanu-to-nanu calls and nanu-out call credit allocation for calls to landlines and mobile phones without the app, for free, could mean the end of phone bills.
nanu operates on an advert-funded call model where users' nanu-out calls are sponsored by adverts in the form of voice ads played over a ringtone.
These voice ads stop as soon as a recipient answers the call, allowing this to be completely non-intrusive.
nanu's goal is to improve the communications experience of users and connect brands with consumers through an effective mobile advertising platform.
