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 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 billions of mobile ads daily in order to hyper-target
app install ads for our clients.

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