PubMatic

PubMatic runs a sell-side advertising platform that lets publishers, app developers and streaming services sell their ad inventory programmatically to advertisers and agencies. Its supply-side platform manages auctions, yield and header bidding wrappers across display, video, mobile and connected TV. Activate gives buyers a way to run direct deals for video and CTV without a demand-side platform, and Convert helps retailers and marketplaces build retail media networks. Connect packages inventory and data for buyers, and identity and agent-based tooling support planning and execution. The company is publicly listed and based in Redwood City, California, with offices around the world.
