Global exchange for advertising Rubicon Project has today announced the acquisition of open source header bidding solution RTK.io.

RTK’s solution is built on Prebid, the same open source framework as Rubicon’s Demand Manager. RTK’s technology and team enable Rubicon Project to extend its Demand Manager product portfolio and client base.

In the coming months, the company plans to integrate the two solutions to address the growing needs of publishers globally.

Rubicon Project acquired RTK in an all-cash transaction for $11 million.

“RTK shares our commitment to open source and our passion for serving publishers with powerful tools and incredible client service,” said Rubicon Project CEO Michael Barrett, President and CEO.

“The company has a strong group of header bidding experts and Prebid developers that adds depth to our already great team. Together, we will accelerate our shared vision of helping publishers regain control of their monetisation and make quick, informed decisions to grow their businesses.”

Founded in 2014 and headquartered in New York City, RTK is a programmatic infrastructure and ad operations company dedicated to making ad tech more efficient. RTK provides publishers with an integrated user interface to configure, install, and implement a complete header bidding solution. In addition, the company’s reporting and analytics capabilities are extremely fast and flexible, driving better yield management.

“We are thrilled to be joining Rubicon Project and look forward to being part of the Demand Manager team,” said RTK co-founder and CEO Gareth Glaser.

“Rubicon Project’s resources and footprint supporting our integrated product will enable us to bring new levels of service and innovation to publishers globally, and to further our shared vision of bringing a transparent and collaborative approach to the industry.”
