We founded Sift in 2015 around the idea that the unique set of apps each of us has installed on our smartphones is like a digital fingerprint of who we are and our interests.


So we set out on a mission to collect this data for every smartphone user. Now with more than 2.1 billion unique profiles of smartphone users around the world, we leverage all of this data and advanced AI & machine learning algorithms to
sift through 50 billion mobile ad requests daily in order to hyper-target
app install ads for our clients.

“The average smartphone user has 41 apps installed.”
— Nielsen
