Metamarkets Group

Metamarkets was a real-time analytics platform for programmatic advertising, giving ad exchanges, SSPs, DSPs, and ad networks interactive dashboards over billions of daily bid, impression, click, and spend events. Its Real-time Data Ingestion (RDI) API accepted continuous streams of OpenRTB-based JSON event records over authenticated HTTPS POST, surfacing them in the Metamarkets dashboard within seconds. Founded in 2010 and the birthplace of the Druid analytics database (now Apache Druid), Metamarkets was acquired by Snap Inc. in 2017; its successor products live on as Rill Data. This profile enriches the dcvc portfolio lead from the surviving public documentation at docs.metamarkets.com.

Metamarkets Group publishes 1 API on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Analytics, and Programmatic Advertising.

Metamarkets Group’s developer surface includes documentation, getting-started guide, authentication, sandbox, and 8 more developer resources.
