DoorDash Expands Advertising Platform with AI Tools and Symbiosys Acquisition
DoorDash has launched a significant update to its advertising platform, introducing a suite of AI-powered tools and announcing the acquisition of ad tech platform Symbiosys, announced in a press release. This move aims to enhance offsite advertising capabilities across search, social, and display channels.
The new AI tools are designed to help restaurants and brands drive measurable growth by providing more control, sharper insights, and broader reach. DoorDash and Wolt Ads currently serve over 150,000 advertisers in more than 30 countries, making it a leading global growth engine for local commerce.
The acquisition of Symbiosys, valued at $175 million, will allow DoorDash to expand its advertising reach beyond its platform, offering advertisers the ability to run campaigns across various digital channels with integrated closed-loop measurement. This development reflects DoorDash's investment in global ad technology, empowering businesses to connect with high-intent consumers both on and off the platform.
