Mediarithmics is the first Cloud platform dedicated to the crossroads between Big Data and digital marketing : Data Marketing. Mediarithmics is a tool that allows companies themselves to address, on the web, the advertising of their products to the right users at the best time. Thanks to this platform, brands can take control of their large volume of data and use it to target the right clients through adapted advertising and customized messages. Companies can thus organize their own advertising campaigns, multi-screen and on all digital channels (RTB Display; Facebook, email, text messaging, on-site / in-app communication). This autonomy also allows them to save money on their marketing investments.
