GoGuardian (Liminex, Inc.)
The Los Angeles company that turned the Chromebook boom in US schools into a device-filtering, classroom-management and student-safety monitoring business. With private-equity backing from Sumeru Equity Partners, a $200m Tiger Global investment and the 2020 merger with Pear Deck, it became one of the largest K-12 software platforms in the country. It is also one of the companies most often named in the debate over student surveillance.
