Brian Mandelbaum is best known as the CEO of Klover, a consumer data and rewards platform that has carved out a distinctive niche in AdTech by incentivizing consumers to share first-party data in exchange for cashback rewards and financial tools. Under his leadership, Klover has emerged as a notable example of a consent-based, privacy-first data model that addresses the industry's urgent need for third-party cookie alternatives, positioning the company at the intersection of fintech, consumer engagement, and programmatic advertising. Mandelbaum's career has been rooted in the advertising technology ecosystem, with prior leadership roles at digital media and AdTech companies where he developed expertise in programmatic advertising, data monetization, and publisher monetization strategies.

His background reflects a consistent focus on bridging consumer behavior insights with advertiser demand in measurable, performance-driven ways. As privacy regulations have reshaped the digital advertising landscape, Mandelbaum has been a vocal advocate for transparent, consumer-permissioned data models.
