To do so, we build Machine Learning and Big Data-driven technology that can accurately predict which apps a user will like, and connect them in a compelling way. Our systems operate at a scale unseen outside of the largest Internet companies -- processing over a million requests per second and interacting with over a billion users. Our technology is innovative and we have strong product-market fit; as a result, we've already reached profitability and are seeing tremendous growth.
