Mike Feldman is best known for leading Reddit's advertising revenue organization during one of the platform's most critical growth phases, helping establish Reddit as a legitimate and scaled destination for brand and performance advertisers. As Chief Revenue Officer, he oversees the full commercial advertising operation, including sales, partnerships, and go-to-market strategy, at a time when Reddit has been aggressively expanding its ad products and preparing for and executing its IPO in 2024. Before joining Reddit, Feldman held senior sales and revenue leadership roles at major players in the digital advertising ecosystem, including time at Xandr (formerly AppNexus/AT&T's ad platform) where he developed deep expertise in programmatic advertising, data-driven targeting, and enterprise-level media sales. His background spans both the buy and sell sides of the advertising industry, giving him a nuanced understanding of advertiser needs and publisher monetization strategies. Feldman has been instrumental in professionalizing Reddit's advertising sales force, building out its agency and brand relationships, and expanding the platform's appeal to performance and brand advertisers alike. His leadership has coincided with Reddit's push to improve its ad measurement capabilities, brand safety tools, and self-serve advertising infrastructure, positioning the platform competitively against social media peers.
