Adobe Experience Platform Launch is a new "next-gen" tag management solution. Like Adobe's other tag management product, Dynamic Tag Manager, Launch is based on the acquisition of Satellite from Search Discovery in 2013. But Launch is built to facilitate a more open, integrated marketing technology stack. Launch plays nicely with Adobe and non-Adobe products. It includes an open API and a catalog of extensions (like an app store of pre-built integrations to other platforms) so that data can flow across the user's marketing ecosystem.
For users of DTM who want to upgrade to Launch, Adobe offers the ability to redirect existing DTM embed codes to point to Launch by Adobe.
