Lionsolver Team

Lionsolver team is driven by a passion to “measure what is measurable, and make measurable what is not so,” a passion we share with Galileo and other proponents of pragmatic and falsifiable models of business reality, based on experiments and honest interpretation of the data.

We realize software and services for adaptive analytics, Learning and Intelligent OptimizatioN, marketing optimization, "big data" (a recent keyword covering methods created in a seminal form at least two decades ago). Our competitive edge is caused by a unique integration of machine learning and optimization. The founders and collaborators have more than twenty years of experience and a track of successful real-world applications in wide different areas and ... they keep having fun together.
