Gavin Buxton

Gavin Buxton is a senior programmatic advertising executive known for building and scaling supply-side platform (SSP) operations across the Asia-Pacific region. As Managing Director, Asia at Index Exchange, he leads business development and publisher partnerships spanning Australia, Japan, Singapore, and Southeast Asia, navigating the unique complexities of APAC markets where fragmented publisher ecosystems and diverse regulatory environments require tailored approaches distinct from Western programmatic models. Buxton has been instrumental in advancing header bidding adoption and supply path optimization (SPO) initiatives across APAC, working closely with publishers and agency trading desks to improve transparency and efficiency in programmatic supply chains. His work reflects a deep understanding of how programmatic infrastructure must be adapted for markets with varying levels of digital maturity, local language inventory challenges, and distinct buyer-seller dynamics. With over a decade of experience in digital advertising across the Asia-Pacific region, Buxton has established himself as a key figure in the regional AdTech ecosystem, representing Index Exchange's interests at industry forums and contributing to broader conversations around supply path transparency and the evolution of programmatic trading in emerging and established APAC markets.
