AI-powered student safety platform monitoring school device and personal app activity for cyberbullying and mental health risks. Atlanta GA, raised $24M+.
About
Bark Technologies is a student safety company that uses AI to monitor student online activity across both school-managed devices and personal apps, detecting signs of cyberbullying, depression, suicidal ideation, sexual content, and other risks, and alerting parents or school administrators when concerning patterns are identified. Founded in 2015 and headquartered in Atlanta, Georgia, Bark serves both individual families through a consumer subscription and school districts through its Bark for Schools product. The company has raised more than $24 million and has processed billions of messages to help identify students at risk.\n\nBark's approach is privacy-conscious by design — rather than giving parents or administrators access to read all student messages, it uses AI to analyze content and only surfaces alerts when problematic patterns are detected. This balances the legitimate safety need to identify at-risk students with the developmental need for adolescent privacy, a distinction that differentiates Bark from more invasive monitoring tools. The system monitors more than 30 platforms including Gmail, Instagram, Snapchat, TikTok, YouTube, and others, covering the breadth of channels where problematic student activity occurs.\n\nBark for Schools extends this monitoring capability to school-managed accounts and G Suite / Microsoft 365 environments, integrating with district technology infrastructure. The company competes with GoGuardian Beacon, Securly Aware, and other student mental health monitoring tools, as well as with broader student safety platforms. Bark has earned strong trust among school counselors and parents due to its detection accuracy, privacy-preserving design, and documented track record of helping schools identify and support at-risk students.
