123Push
123Push segments are provided by Stirista.
According to sources, programmatic media agencies objected to Stirista running campaigns in competition with them so they stopped using Stirista audiences. Stirista then silently launched 123Push segments without their name or a website as way to get advertiser usage reports from LiveRamp to promote their own DSP to clients directly – a trojan horse attempt?

123Push is Stirista trademark. Any references to Stirista or 123Push are for informational purposes only.
