Glystn is the cultural intelligence layer: an AI-native platform that turns the world's social conversations — video, comments, creators — into strategic and consumer insight for agencies, brands, and publishers of any size. Think of it as a 24/7 focus group, and a social layer for AI — millions of conversations analyzed daily across TikTok, Instagram, and YouTube, with the evidence attached. A Glystn agent is a custom AI workflow, at your command: pre-built for creator vetting, trend tracking, and brand intelligence, or built around your team's own methodology, most in under a week. Nothing else in social works this way. Glystn runs in production at some of the world's largest agencies and holding companies, including Stagwell's The Marketing Cloud, Influential, Weber Shandwick, Horizon Media, and 456 Growth Media. Founded in 2021 · San Francisco · Backed by Precursor Ventures, Eniac Ventures, Sfermion, and HannahGrey. See it live: app.glystn.com · Free trend reports: app.glystn.com/trends
