Better-than-Amazon personalisation for the rest of the internet. We turn massive behavioural data sets into real-time personalised product recommendations and intelligent deal filtering used to grow conversions, order values and loyalty. To do this, we utilise divisions of machine learning including collaborative filtering and clustering to enable matrix completion, prediction and propensity modelling; enabling 1-to-1 personalisation. PA applies these technologies through our data trackers and cleansing system, augments user experiences via our widget platform, and optimises revenue uplift for our retail clients through both reinforcement learning and expert managed services.
