John Baudhuin is the owner of Mad Dogg Athletics. In 1994, Baudhuin told his dad that he was quitting his day job as a CPA to co-found Mad Dogg Athletics, a fitness startup who ended up inventing an entire category – indoor spinning. 25 years later, John and his team not only defined the category, but they ended up scaling to over 35,000 facilities, presence in over 80 countries, and they’ve gone on to certify more than 300,000 instructors globally.
