"Rexer Analytics provides outstanding and affordable statistical analyses of customer behavior and trends.  We used them to tell us which customer segments we need to target to increase profits and which segments we need to stay away from.  Their analysis was extremely well presented and very clear.  I would highly recommend Rexer Analytics to anyone.  They are the first firm I call for any data mining and statistical work."

"Rexer Analytics hit a grand slam for us!  Their expertise and mastery of data mining and predictive analytics found important patterns in our data where others had failed.  They built multiple predictive models that predicted student success, the likelihood of a student dropping out of college, and the likelihood of a student defaulting on their student loans.  And Karl was outstanding when presenting the information to non-technical audiences.  His slides and explanations were clear and resonated with the audience.  Karl and his team were amazing to work with and I would hire them again in a heartbeat."

CIO - Cegment,  Inc.
"Rexer Analytics assisted our international PwC benchmarking team in the production of our 2013 and 2015 Corporate Finance white papers.  They did an awesome job, as always.  As good as Karl and his team of Paul and Heather were two years ago, they upped the result this time around.  Their data analysis, ad hoc data fulfillment, writing, editing, proofing, project management, dozens and dozens of interviews and, not the least, positive attitude and continuous assistance were tremendous."

Ed Shapiro
Director, Finance Effectiveness
"I highly recommend Rexer Analytics.  Very few quant people possess the total package: excellent credentials, strong statistical and data mining skills, the initiative to anticipate client needs, compelling and concise communications, strong client management skills, and a results-driven mindset.  They’ve led numerous projects that have helped our company maximize marketing efforts and understand our customers better.  In all, the quality has been superior and their client-service attitudes are tremendous."

"The models created by the Rexer Analytics team enabled us to target our retention efforts and take immediate action to retain at-risk customers.  The insights from their analyses also enabled us to make strategic decisions which boosted customer lifetime value."

"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!"

"Rexer Analytics has been instrumental in helping advance the field of data mining through applied research, software evaluation, testing, professional conference support and consulting.  Their research evaluating the trends and preferences among the data mining community is a great resource for many."
