Chief Advisor

Ari oversees MediaMath’s Product & Engineering teams, focused on designing, developing, and supporting best-in-class product solutions and platform capabilities for MediaMath’s customers. Ari brings a unique combination of business leadership, strategic vision, practical marketing knowledge, and quantitative expertise. Whether it’s designing MediaMath’s proprietary Brain optimization algorithm, unifying marketing approaches across digital channels, innovating new targeting technologies, or building the open marketing platform of the future, Ari is impassioned by the chance to work on industry-transforming solutions and humbled by the opportunity to lead the best technology team in the business.

Ari’s passion for big ideas and all things quantitative comes from his first career in academia. Ari was a postdoctoral Fellow in Theoretical Astrophysics at Caltech, having received a PhD in Astrophysics from Columbia, and a Bachelor of Science in Physics from Stanford. While at Caltech building quantitative models of the origin and expansion of the Universe, Ari also applied those modeling skills to Finance, founding and managing a small quantitative hedge fund based on proprietary algorithmic derivatives trading strategies, before making the leap from the ivory tower to the business world. Ari was an Associate Principal at McKinsey & Company in their Global Media & Entertainment Practice, focusing on Marketing Strategy, Customer Analytics, and the design of Marketing Acquisition and Retention programs for leading global media companies. Ari was also a founding member of McKinsey’s Innovation Practice, helping companies tackle the challenges of designing, developing, and commercializing product and process innovations at scale.Prior to MediaMath, Ari was a Senior Partner at leading interactive agency Rosetta and head of their Digital Media & Technology practice, leading major business strategy engagements and marketing program implementations at Fortune 500 clients in the Telecom, Media, and Technology sectors.

When not putting his talents to use around a conference room table, you may find Ari applying them at a poker table, especially during his annual pilgrimage to the World Series of Poker.But what he enjoys most is spending time with his wife Ellie and three sons Benjamin, Isaac, and Abel.
