How Doordash uses AI to scale ads globally

For DoorDash, scaling advertising globally meant more than simply increasing spend or launching campaigns in new regions. The team’s primary goal was to learn fast, to understand what creative truly resonated with audiences and to do so at a pace that allowed continuous iteration and improvement.

Creative was central to that strategy. High-performing creative consistently drives better results, but producing it at scale is notoriously difficult. Generating a large volume of ads, testing variations, and refining messaging across markets requires speed, coordination, and precision. Doing all of that while maintaining brand consistency and relevance for local audiences adds another layer of complexity.

This challenge became even more pronounced as DoorDash expanded into international markets. Scaling across 10 different countries and dozens of languages meant balancing global brand standards with local nuance. Traditional creative workflows simply weren’t fast or flexible enough to support the level of testing and learning the team needed.

That’s where Airpost came in.

Airpost partnered with DoorDash to bring technology into the creative process in a way that was practical and effective. Instead of slowing teams down, Airpost enabled DoorDash to produce large volumes of localized, on-brand creatives within days, not weeks. This speed allowed DoorDash to rapidly test new ideas, expand learnings across regions, and quickly identify winning creative combinations.

Equally important, the creatives didn’t just scale, they worked. Local teams across different markets found the assets effective and relevant, which reinforced confidence in the approach and ensured adoption across regions.

Beyond execution, the partnership stood out because of how Airpost worked with the DoorDash team. Rather than applying a one-size-fits-all model, Airpost acted as a true collaborator. They were willing to push back, offer honest feedback, and focus on what would actually drive results instead of simply executing requests.

The outcome was measurable impact. DoorDash saw lower CPAs, higher click-through rates, and stronger engagement, allowing the investment in creative to pay for itself within weeks. Over time, as the teams continued working together, Airpost’s understanding of DoorDash’s brand and needs only improved, reinforcing the relationship as a long-term partnership rather than a short-term solution.
