Guy Rosen is an Israeli-American technology executive renowned for his contributions to mobile analytics, cybersecurity, and platform integrity in social media. Born on June 1, 1977, in Israel, Rosen earned a Bachelor of Science in Computer Science from the Technion – Israel Institute of Technology in 1999. He co-founded Onavo in 2008, a mobile intelligence company specializing in data analytics tools that helped developers understand user behavior and market trends on mobile devices. Onavo gained attention for its VPN-based app that compressed data and offered insights, but faced criticism for privacy practices. In 2013, Facebook acquired Onavo for a reported $70-100 million, after which Rosen joined Facebook (now Meta Platforms). He rose through the ranks, serving in key leadership roles focused on security and integrity, including as Vice President of Security addressing threats like hacking and data breaches. Since around 2017, Rosen has served as Vice President of Integrity and Product Management at Meta, leading initiatives to protect users from misinformation, election interference, hate speech, and other forms of online harm. His work has been pivotal in Meta's efforts to enhance transparency and trust on platforms like Facebook and Instagram, often involving collaborations with governments and NGOs on global policy issues, including testifying before Congress on content moderation and disinformation during the 2020 U.S. elections. Rosen's career includes prior roles at Webcollage and other startups before Onavo. Onavo's tools were controversially used post-acquisition to monitor competitors like Snapchat and WhatsApp, leading to allegations of anticompetitive behavior; Apple banned Onavo from the App Store in 2019 over privacy violations, prompting Meta to shut it down. Rosen has faced criticism for Meta's handling of hate speech and political ads, with reports accusing the platform of insufficient action against foreign interference, and his tenure has involved navigating regulatory scrutiny from bodies like the FTC and EU over privacy and monopoly concerns. His background reflects a blend of Israeli innovation and American tech entrepreneurship, and he has been vocal on topics like cybersecurity and digital privacy, drawing from his experience in Israel's tech ecosystem. While maintaining a relatively low public profile outside professional contexts, his influence extends to shaping how major platforms balance innovation with ethical responsibilities in the digital age.
