However, he did say that he is interested in continuing standards work around ad inventory and the transparency of programmatic transactions. He added that his time spent at TTD was rewarding because it was an opportunity to make meaningful changes to the ad tech supply chain.

Spencer also worked with Patrick McCann, a Prebid board member and Raptive's SVP of research, to develop the OpenRTB Transaction ID standard, which Prebid implemented into its auction wrapper."
