We are doing hidden marketing & PR in social networks for mobile apps & games with over 300 million audiences resulting in million+ new organic installs monthly and significant ranking growth. Advertisers pay only CPI and we do the rest! Our promotion looks like recomendations from top influencers in major social networks to their folowers. Example: "I played Jungle Heat mobile game all night long! It's awesome!" All installs are organic and not motivated, 90% of installs from US iPhone AppStore and some more from other English-speaking countries such as Canada, UK. All installs have high ROI.
