Shenan Reed is best known as a co-founder and long-tenured CEO of Sharethrough, one of the pioneering native advertising exchanges and supply-side platforms in the programmatic ecosystem. Since co-founding the company in 2008, Reed has shaped how native advertising is bought and sold at scale, helping establish industry norms around in-feed ad formats that integrate naturally with publisher content rather than disrupting the user experience. Sharethrough has grown under his leadership to process billions of impressions globally and counts major brands and premium publishers among its partners. Beyond native advertising, Reed has emerged as one of AdTech's most prominent advocates for environmental sustainability. He has been instrumental in pushing the industry to confront the carbon footprint of digital advertising, championing the development of measurement tools and methodologies that help advertisers and agencies quantify and reduce emissions associated with programmatic campaigns. This work has positioned Sharethrough as a recognized leader in green AdTech and has influenced broader industry conversations at organizations like IAB and Ad Net Zero. Reed is regarded as both an operator and a thought leader, having built and scaled a company while simultaneously contributing to standards and discourse that extend well beyond Sharethrough. His dual focus on technology innovation and responsible advertising practices has made him a distinctive figure in an industry often criticized for opacity and environmental impact.
