MediaMath will celebrate its 10th birthday next year. A lot has changed since 2007, when Joe Zawadzki, Erich Wasserman and Greg Williams came together to start the industry’s first demand-side platform. From a shoebox office of a handful of employees to a global operation with 750 employees in 16 locations around the world, MediaMath has certainly grown into its own. But the early days weren’t easy, as our CEO Joe Z explans in this video on our founder’s story. Watch the clip to hear about one fateful Thanksgiving in the early days of the business when he accidentally turned a client campaign upside down and the work it has taken to get MediaMath where it is today.
