About Jeff Ma

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 was the inspiration for 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 corporate speaker.
Beyond his work as an entrepreneur, Ma has been a pioneer in the “Moneyball” movement working with professional sports teams like the San Francisco 49ers and the Portland Trail Blazers and media powerhouses like ESPN and Major League Baseball Advanced Media, helping them to make better decisions using data and 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.

His time in Vegas, in sports and as an entrepreneur make him one of the leading speakers on how big data is changing the world. Ma’s speeches are entertaining, accessible and informative as he weaves tales of winning millions of dollars at the tables with discussing stats with the like of Jerry West, Billy Beane and Bill Walsh with stories of how avoiding cognitive biases can grow your business. Audiences across the globe have listened intently to Ma tell a story and deliver a message that no one else can.

In 2012, Ma founded a company called tenXer with the vision to revolutionize human capital management by using data and analytics to create better management, recruiting and evaluation tools. In April of 2015, tenXer was acquired by Twitter. Ma is currently the Senior Director of Business Insights at Twitter.

  3. Hey Jeff just read your book “The House Advantage” and loved it. I’ve got an idea for Fantasy Sports that I think could change the way it’s played and wanted to get some feedback to see what you think.

  4. Jeff,
    Good luck today with your presentation at the Bellagio. Wish I could be there for your keynote speech but I am now working on different projects. I’m sure you’ll do a fantastic job! Thanks so much for participating in the GroPro event!
