4INFO is an American firm that allows its clients to provide text message alerts and information to their consumers. The ad tech company claims it has a reach of over 95% of U.S. smartphone users.

To do so, the platform utilizes smartphone-household location data to gain insights about its users. Essentially, 4INFO targets the desired audience by leveraging CRM data or third party segmentation or purchase data. The method is described in its patent abstract:

Embodiments of the invention relate to methods and systems for associating a mobile device to a household. In various embodiments, a plurality of latitude-longitude pairs is received for a mobile device during a time period. The latitude-longitude pairs are organized into a plurality of clusters corresponding to geographic regions visited by the mobile device during the time period. For each cluster, a score is calculated that represents a likelihood that a user of the mobile device resides in a household within the cluster. The cluster with the highest score is identified as being the location of the user’s household. The computation is preferably conducted recursively over time periods. The mobile device is then associated with the user’s household.

From Wikipedia:

The company’s products collect data on the extent to which its clients’ customers are exposed to their advertisements.

As of 2014, the company offers multi-screen functionality (mobile and desktop display).

When it was founded in 2004, 4INFO began as a text-based SMS advertising company. The company is now headquartered in San Mateo, California, with offices throughout the U.S.
