The startup is a spinout of MIT's Media Lab, where researchers were working on ways to create new technologies that would enhance emotional communication and, yes, it already started offering'Emotion As A Service' late last year. The company has what is thought to be the world's largest database of emotions, gathered using facial recognition technology to analyze over 3.8 million faces from 75 countries and collating over 40 billion different data points.
