MediaMath CEO Joe Zawadzki is a respected pioneer in the online marketing industry, known especially for establishing the demand-side platform sector. With his deep experience in audience targeting and optimization, ad networks and exchanges, and real-time bidding Joe is regularly invited to speak at industry conferences, roundtables and major events.

After a decade representing buyers at top-tier agencies and Fortune 500 companies, Joe Zawadzki saw the need to reshape the online marketing landscape by integrating technology, data, analytics, and marketing best practices into a single media platform. He founded MediaMath in 2007, launching a technological revolution with the company’s pioneering marketing OS, TerminalOne, the first DSP.

Previously, Joe was founder, president and chairman of Poindexter Systems / [x+1], incubated Right Media, and as managing member of Occam’s Razor, shaped AOL’s yield management and DoubleClick’s buy-side optimization strategy.

His early career was spent as an investment banker, where he developed his expertise in quantitative analysis and market dynamics, and he remains an active New York technology investor whose portfolio includes AppNexus, AdSafe, 33Across, C3Metrics, Hashable, Accordant and Spruce Media.

Joe holds several patents in the area of online methods for dynamic segmentation and content presentation. He is a graduate of Harvard University and was a Teaching Fellow in cosmology, set theory and the history of science.

Ari oversees both MediaMath's Product team, focused on designing and delivering best-in-class product solutions to the market, as well as the Business Operations group that uses MediaMath’s technology to deliver exceptional results to clients. Ari brings a unique combination of business leadership, strategic vision, deep and practical marketing knowledge, and quantitative expertise. 



Previously, 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. Prior to that, he was an Associate Principal at McKinsey & Company in their Global Media & Entertainment Practice, focusing primarily 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.



Ari’s passion for big ideas and all things analytic (including the design of MediaMath’s proprietary Brain optimization algorithm) comes from his first career in Theoretical Astrophysics. 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 finally making the leap from the ivory tower.



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 two genius-in-the-making sons Benjamin and Isaac.

Roland oversees the architecture and development for MediaMath's TerminalOne platform. With over a decade of experience in enterprise level software design, end-user windows applications, and web-based systems, he brings a tremendous depth of technical knowledge to the MediaMath team.

Roland's initial foray into the business world started in the Marketing Research sector, where he was surprised to find use for a degree in mathematics (BA Washington University, Saint Louis). This stint was short-lived, as he realized he wanted to write code, something he had done since childhood on an Apple II.

During the internet boom, he ran engineering for Tempest Software, building low-level messaging systems, and for WhenU as VP of Engineering, where he developed the first behavioral targeting and content contextualization engine. For the past several years he ran his own consulting and development firm, working with a large list of fortune 500 clients, developing code ranging from quantitative algorithms for financial trading, secure instant messaging solutions, compliance systems, digital rights management, to web applications too numerous to name. He is the rare technologist who understands the end to which code is the means.

His passion of technology and art exposed him to over 25 programming languages, 3D modeling, video post production, and sound engineering. He even found the opportunity to compose a score for a nationally televised commercial. Its safe to say he strives to continuously learn anything he can and add a layer of creativity not often found within the development community.

When time permits he still likes to trade equities, build furniture and play music ... and even fire up a chainsaw now and again. Most importantly, he always makes time for his wife and 3 boys. As he sees it, he's just 2 skaters away from a hockey team.
