Jason O'Toole Named EVP, Head of Commerce & Retail Media Activation at dentsu

Jason O'Toole has taken on the role of EVP, Head of Commerce & Retail Media Activation at dentsu, expanding his responsibilities across the agency group's commerce and retail media operations.

The move comes as retail media continues to develop from a specialized advertising channel into a broader component of brands' media and customer strategies. Retailers and commerce platforms are increasingly building advertising businesses around first-party customer and transaction data, creating new opportunities for brands to reach consumers closer to the point of purchase.

For agencies, this evolution has increased the complexity of media activation. Campaigns can now span retailer media networks, marketplaces, social platforms, programmatic environments, and other digital channels. Coordinating these activities requires integration between media planning, audience data, technology, measurement, and client teams.

O'Toole's new role comes as marketers increasingly focus on connecting media activity with commercial outcomes. Retail media offers advertisers access to purchase-related signals that can help marketers understand audience behavior and evaluate campaign performance. However, comparing results across different commerce platforms remains a challenge because measurement standards and available data can vary.

Artificial intelligence is also influencing retail media activation. AI and machine learning are being used for audience segmentation, bidding, forecasting, campaign optimization, and personalization. As these tools become more common, marketers must also consider data governance, privacy, transparency, and the quality of automated decision-making.

The growing importance of first-party data is another factor reshaping the sector. Retailers and commerce platforms possess valuable information about customer interactions and purchases, while brands are looking for ways to responsibly connect those insights with broader marketing activity.

For the wider MarTech and AdTech ecosystem, commerce media represents an increasingly close relationship between advertising, technology, customer data, and transactions. Activation teams are becoming responsible for more than simply placing media; they must also consider how campaigns work across platforms and contribute to measurable business objectives.

O'Toole's appointment reflects this shift and the growing importance of dedicated leadership around commerce and retail media activation.

As the sector develops, agencies and advertisers will continue to navigate questions around measurement, interoperability, privacy, and the effective use of data and AI. These factors are likely to shape how commerce media evolves and how brands connect media investment with customer outcomes.
