Jared Belsky is one of the more prominent operator-executives bridging the agency and ad tech worlds, best known for leading Beeswax, the customizable demand-side platform acquired by Comcast in 2021. At Beeswax, he has championed the idea that sophisticated programmatic buyers deserve transparent, flexible infrastructure rather than black-box solutions — a positioning that has resonated strongly with agencies, trading desks, and large direct advertisers seeking alternatives to walled-garden DSPs. His leadership has helped Beeswax carve out a distinct niche in a crowded programmatic landscape by emphasizing bidder-as-a-service technology and open infrastructure. Before joining Beeswax, Belsky spent more than a decade at 360i, one of the most respected independent digital agencies in the United States. Rising through the ranks to serve as President of Partnerships and Platforms, he was instrumental in building 360i's programmatic capabilities and forging relationships with major technology platforms at a time when the agency ecosystem was rapidly evolving. His agency-side experience gave him a practitioner's perspective on the pain points of programmatic buying — transparency, cost efficiency, and control — that directly informed his work at Beeswax. Belsky is widely regarded as a thoughtful voice on programmatic advertising's structural challenges, including supply chain transparency, the limitations of managed-service DSPs, and the evolving role of identity in a post-cookie world. He has been a consistent presence on industry stages and in trade press, advocating for advertiser empowerment and more accountable ad tech infrastructure.
