It will support multiple advertising formats, including sponsored products, sponsored brands, display ads, video ads, and off-platform campaigns.

The team will build capabilities across campaign management, advertiser onboarding, product catalogue integration, audience activation, auction and ranking, budget and pacing, ad serving, measurement, attribution, reporting, and partner integrations.
