Civitai: Open Sourcing AI Art

Justin Maier, Maxfield Hulker, Maxville Holker

Co-founded by Justin Mayer and Maxville Holker, the platform Civitai rapidly scaled to one million users by March 2023 to consolidate open-source image technology and host community-created models. The site differentiates itself through detailed metadata tracking, automated content safety via Safe Prompt Models, and integrated tools that allow users to train custom LoRAs from uploaded data. By balancing unrestricted creative expression with necessary moderation, the organization currently fosters a growing creator economy where developers can monetize their work without sacrificing open accessibility.
