Documented cause
Manticore Games, creator of user-generated content platform Core (often called 'Roblox for adults'), raised $100M from Andreessen Horowitz and others. CEO Frederic Descamps positioned Core as a game creation metaverse. Despite a free PC launcher and thousands of creator-made games, monthly active users never exceeded 500K and monetization remained weak. In 2024, Manticore conducted sweeping layoffs affecting over 50% of staff and wound down Core's active development.
Lesson
“UGC platforms need network effects before Series B; without creators AND players simultaneously, neither stays.”
