| PressBox was founded by ex-Bleacher Report engineers who saw where AI could help media organizations scale the discovery, creation, and measurement of personalized content across a variety of platforms.

Sports organizations are looking to personalization to meet this rapidly growing portion of the fan base, but lack the end-to-end solution to deliver revenue-producing results.
