Input: Over time  Trade Desk CEO Jeff Green believes that Google and Facebook will be forced to become far more flexible with their ad data.
"Our ID footprint will be larger than any single company login footprint "  Trade Desk CEO Jeff Green  said during the company's investor day in New York on Wednesday.  Green  is referring to the various ways people log-in to web sites and apps  providing information on their names  locations  interests  relationships – all of which can be used to identify people and target them with relevant ads.
 Green  noted that while Facebook has 1.3 billion active users  there are over 4 billion web users in the world  a number that continues to grow.
To that end  Green  said that  the company  has recently signed a deal with a major telecom company to license some of  its  consumer data for ad targeting. He declined to name the telecom firm.
In addition  the ad tech company has similar deals in the works with a dozen of the largest web publishers   Green  said. Presumably  these are sites that encourage people to register and log in in some fashion.
Over time   Green  wants to rent log-in data from other social networks  audio streaming services and big dating sites. In the end  he believes he'll have more info on consumers than either duopoly giant.
