Ari Buchalter is a recognized thought leader on digital media strategy, programmatic media buying, and advanced marketing analytics & optimization techniques. His unique career spans from cutting-edge PhD and postdoctoral research in theoretical astrophysics at Stanford, Columbia, and Caltech, to over a decade of leadership in marketing strategy and digital media innovation at McKinsey, Rosetta, and MediaMath.

As President, Technology of MediaMath, 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.

Prior to MediaMath, Ari was a Senior Partner at Rosetta, the nation’s largest independent digital marketing agency, where he led the Digital Media & Technology practice, tripling the business in less than 3 years. In that role, he led dozens of major marketing strategy and implementation engagements for Fortune 500 telecom, media, and technology clients, with a focus on leveraging segmentation and data-driven consumer insights to develop customized, cross-channel consumer marketing programs driving measurable improvements in ROI. Earlier in his career, Ari was an Associate Principal in McKinsey & Company’s Media & Entertainment practice, advising media and technology companies in marketing strategy, digital media strategy, marketing analytics and customer lifecycle management. He was also a founding member of McKinsey’s Innovation practice, working with industry-leading companies in a variety of sectors on the challenge of fostering innovation in large businesses.

Ari’s focus on “big picture” thinking and love for all things analytic come from his first career in Theoretical Astrophysics. Ari holds a BS in Physics from Stanford, a PhD in Astrophysics from Columbia, and went on to hold the Lee A. DuBridge Prize Postdoctoral fellowship in Theoretical Astrophysics at Caltech. While at Caltech building mathematical models to describe the origin and expansion of the universe, Ari was intrigued by the application of similar methods to the world of business, and the real-world impact these could have. While at Caltech, he founded and managed a small quantitative hedge fund focused on algorithmic derivatives trading, before finally making the leap from the ivory tower. His passion for problem-solving, and in particular the application of techniques and approaches from different disciplines, continue to motivate him to devise visionary yet practical solutions to modern marketing challenges. Ari has spoken about analytics, optimization, and improving marketing effectiveness at numerous industry conferences and events. In addition to his many scientific papers and presentations, Ari has published in the McKinsey Quarterly and contributed articles to various industry websites such as iMedia and AdExchanger.

Ari enjoys spending every non-working moment with his wife Ellie and sons Benjamin and Isaac. And if you’re in Las Vegas in June, you may bump into him during his annual pilgrimage to the World Series of Poker.
