Jessica Breslav is a senior demand-side leader at Magnite, the world's largest independent sell-side platform, where she oversees the demand partnerships that connect premium publishers with advertisers across programmatic video and connected TV (CTV) channels. Her work is central to Magnite's marketplace strategy, ensuring that advertiser demand flows efficiently to publisher inventory while supporting the broader shift toward programmatic CTV adoption. She is recognized within the industry for her ability to cultivate and sustain high-value relationships on both sides of the programmatic ecosystem. Breslav's career trajectory runs through SpotX, the video advertising platform that Magnite acquired in 2021 for approximately $1.17 billion. Her retention through that acquisition underscores her standing as a key contributor to the combined organization's video and CTV capabilities. At SpotX, she developed deep expertise in video-specific programmatic infrastructure and demand facilitation, experience that translated directly into her expanded responsibilities at Magnite post-merger. Throughout her career, Breslav has operated at the intersection of publisher monetization and advertiser access, helping to shape how demand-side platforms, agencies, and brands engage with premium supply in an increasingly complex programmatic landscape. Her focus on CTV positions her at one of the fastest-growing and most strategically important segments in digital advertising.
