With close to 2 million beacons and over 60 partners, Unacast is the world´s largest network of beacon and proximity companies, connecting the physical world to the digital world.

Through the Unacast PROX network, Unacast enables a scalable solution for retailers and brands to use beacon and proximity data for online retargeting and attribution.

Online marketing is almost entirely based on whatever online trails the consumer leaves behind. At the same time, the world is being rapidly “sensored up” with beacons and other proximity technologies collecting data about customer’s offline Behavior. The data is however extremely fragmented and siloed between more than 350 companies.

Unacast is the backend of proximity that aggregates and provides a unified platform for the proximity and advertising industry, solving the fragmentation problem to the benefit of both the supply and demand side.

We are the first company to enable a scalable way for retailers and brands to retarget customers online based on behavior in the physical space.
