About the Project

Roku Demand Side Bidding (aka DSP/RTS) DataXu is an omnichannel media management platform, which uses powerful machine learning algorithms to automate media and optimize campaign results — a large part of the system built and supported by Proxet (formerly RailsReactor). DataXu came to us in 2010, when their growth compelled them to augment their engineering team with expert external assistance. The DataXu platform is a highly scalable, low-latency system that evaluates opportunities to bid in auctions for ad space in real-time. In peak traffic, it handles in excess of 2.5 million requests per second with a 95th percentile latency in the tens of milliseconds and is integrated with dozens of ad exchanges. Functionality Includes:

  • Active Analytics. This mixed media solution uses machine learning and predictive analysis to test ad investment patterns, analyze investment against projected outcomes, and optimize media mix across online and offline media down to the region.
  • Detailed Customer Insights. Access detailed customer insights, including age, geographic location, previous brand interaction, and purchase intent behavior. You can also use the report builder feature to visualize the information that’s important to you and your business
  • Marketing Plan Benchmarking. Allows the user to analyze an existing marketing plan for performance and improvements
  • OneView — ability to sync user information across all their devices
