Meet our new Head of Advertising Strategy, Matt Thornton

Cartbloom is growing and today, we’re excited to welcome Matt Thornton as our new Head of Advertising Strategy, joining us at a pivotal moment as we scale our Walmart‑first agency model.

  Matt brings over a decade of experience in Retail Media, having driven growth and innovation across two of the industry’s most influential platforms: Amazon and Walmart. Most recently, as a Senior Partner Manager at Walmart Connect, he partnered with brands to unlock the full potential of retail media through strategies built for measurable impact.

Matt’s expertise spans search advertising, programmatic campaigns, and
custom retail media executions. He has a proven ability to build and refine full‑funnel strategies that not only drive ad‑attributed volume, but also strengthen organic relevancy and expand market share, a critical combination for brands looking to scale on Walmart Marketplace.

As Head of Advertising Strategy, Matt will help shape the next phase of Cartbloom’s growth by leading:

• Advertising strategy & full‑funnel retail media frameworks
• Search + programmatic excellence tailored for Walmart’s ecosystem
• Performance measurement and insights that drive real business outcomes
• Cross‑functional collaboration with catalog, merchandising, and marketplace teams
• The development of scalable, Walmart‑first advertising systems and processes

His background at both Amazon and Walmart Connect gives him a unique vantage point offering brands an understanding of both the mechanics of the marketplace and sophistication of modern retail media.

We’re thrilled to welcome him to the team and excited for what’s ahead.
