Machine Learning  

Fully Automated Media Buying

Since we believe machine learning and mathematics cannot compete with the human brain’s ability to deduce and induce, we pair the mathematical, machine driven conclusions with a neural network algorithm, aimed to mimic the human brain’s decision making mechanisms, The algorithm recognizes unique and complex patterns out of large volumes of data, and compiles actionable user audiences based on this.

Two Years In The Making -

It Was Worth IT

Imagine we told you there was a magical system that plugs in directly to all of the major traffic sources in the mobile world, evaluates over 100,000 ad opportunities every single second and that can make millions of complex algorithmic calculations within less than 10 milliseconds a second; all aimed at making sure you’re bidding on the right impression, at the right time, with the right offer, and for the right price.

Well, this system exists, Meet FIFTY1.
