"Karl Rexer is one my top few most treasured colleagues. His firm is one of the top boutique consulting firms in predictive analytics, and has accumulated an impressive, diverse client portfolio. I’ve had the pleasure to work directly with Karl on several projects, and he’s a regular plenary speaker at the conference series I founded, Predictive Analytics World. When it comes to execution, Karl and his team have conquered the art of clear communication, which is as important as it is rare in the complex arena of analytics. Also, Rexer Analytics’ series of Data Science Surveys is a foundational contribution to this industry’s community. If you have the opportunity to work with Karl’s firm, nab it!"
