Online shopping is booming, but that's not to say that the physical retail store is irrelevant. In fact, people still enjoy the physical shopping experience and a large percentage of transactions are still made in store as opposed to online. Bearing this in mind, the ability to interact and communicate with customers in this environment has huge benefits. Estimote is a sensor-based analytics and engagement platform that is designed to communicate with smart phone users in stores, and get a better understanding of how they behave and engage with products. The Estimote API provides the means for this technology to be integrated with other applications.
Science Rockstars aims to transcend simple recommendation engines and A/B testing techniques to create personal profiles of pitches that persuade individually.

The documentation notes that it can be implemented either on the server or client side (the latter includes a Javasctipt library to facilitate the process).
