MediaMath’s strength is in numbers.  Our technology analyzes 200 billion customer opportunities daily– more volume than the top 10 stock exchanges in the world, combined. Over 700 Mathletes in 16 global offices are trusted by two-thirds of the Fortune 500 and partner with thousands of marketers to ensure brands connect with right audiences, in the right place, in the right time.


We believe consumers want to have meaningful conversations with their favorite and yet-to-be-discovered brands across all digital touchpoints. Our omnichannel, integrated programmatic platform unites digital media and big data to maximize the return on every marketing dollar spent by making advertising relevant, personalized, measurable and controllable.   From inventing the DSP category in 2007 to being named a DMP Forrester Challenger (our first year participating in the DMP Wave!) in 2017, we continue to deliver results for marketers more quickly and accurately than any other solution.
