Cujo LLC

Cujo LLC (operating as CUJO AI) is a privately held American network-intelligence and cybersecurity software company founded in 2015 by Yuri Frayman and Einaras von Gravrock. The legal entity Cujo LLC is registered in Delaware (1209 Orange Street, Wilmington), while the operating business is headquartered in El Segundo, California, with engineering and offices in Lithuania, Hungary, Finland, the Netherlands, the UK, Israel, and Norway. It is private, backed by investors including KPN Ventures and Charter Communications. Third-party trackers estimate headcount in the roughly 200–250 range and annual revenue near $126M; these are unaudited estimates, not company-disclosed figures.

Products / services. CUJO AI sells software (not consumer hardware) to network operators. Its platform applies machine learning to broadband network data to provide connected-device identification and classification, real-time home network security, advanced parental controls and profile-based content blocking, privacy protection, and network analytics. The company has supplied technology behind carrier offerings such as Comcast's Xfinity xFi Advanced Security, and states its software reaches operators including Comcast, Charter, TELUS, Sky, Rogers, Cox, Shaw, Videotron, and EE. This is an operating company with real products and paying carrier customers.

Litigation posture. The structured data shows one tracked case, zero as plaintiff and one as defendant — the profile of an operating company being sued rather than a patent assertion entity. In Kajeet, Inc. v. Cujo LLC (2:20-cv-00253, C.D. Cal., filed January 9, 2020), Kajeet asserted patents covering real-time policy management of user communication devices against CUJO's Smart Firewall and "Compass" operator products. The case was filed in the Central District of California, not an NPE-heavy venue such as the Eastern District of Texas.

Context. Kajeet, a wireless/mobility solutions provider holding a patent portfolio, settled with CUJO and granted a software patent license, dismissing the suit (announced June 1, 2020). Stanford's NPE Litigation Database classifies both parties as product companies/practicing entities, consistent with a commercial dispute rather than NPE assertion.
