Jeff Ma

CEO, tenXer


As a member of the infamous MIT Blackjack Team, Jeff Ma created an ingenious method for counting cards—using talent, creativity, math, and teamwork to win millions in Las Vegas. (Card-counting, by the way, is not illegal; casinos just don’t like it). Ma is the subject of the best-selling book Bringing Down the House and the hit movie, 21, which topped the box office in its first two weeks. He has since helped start four different companies including CircleLending (sold to Virgin) and Citizen Sports (sold to Yahoo) and become a sought-after speaker. Ma shows companies how to harness the power of numbers to make better bottom line business decisions; decisions that, often, are the difference between winning and losing.

Beyond his work in the start up world, Ma has worked as a consultant to the San Francisco 49ers, the Portland Trail Blazers and a major apparel brand, helping them to make better decisions using data an analytics. His most recent book, “The House Advantage: Playing the Odds to Win Big in Business” draws on his unique experiences at the table and in the sports world to create a truly accessible book about analytics.

Ma is currently the CEO of tenXer, where he works with large engineering organizations to use data and analytics to better manage software development teams. In addition, this year, Ma has taken on a new role as ESPN’s Predictive Analytics Expert, making weekly appearances on Sportscenter and writing columns for and The Magazine.
