DSPs DataXu, MediaMath and Turn and SSPs AdMeld, PubMatic and the Rubicon Project are the founding members of the new group called Open RTB.

- SSP to DSP publisher batch synchronization (a method for automatically retrieving publisher properties and creative restrictions for each DSP)
- RTB request standards for publisher creative restrictions
