Civit AI, Inc. is an online platform and marketplace for generative AI content, founded in 2022 by Justin Maier and Maxfield Hulker and headquartered in Boise, Idaho. The company operates Civitai, a community-driven hub for sharing and discovering custom AI models, fine-tunes, LoRAs, and embeddings built primarily around Stable Diffusion and Flux image-generation frameworks.
The Civitai platform enables users to upload, share, and download AI model resources and hosts a gallery of AI-generated images and videos. It supports a virtual creator-incentive currency called Buzz and a developer API at developer.civitai.com. By April 2024, the platform had reached 23.2 million monthly accesses, making it one of the largest open-source repositories of generative AI models.
Civit AI, Inc. raised a $5.1 million Seed round in November 2023, led by Andreessen Horowitz. The company employs approximately 19 people and maintains an open-source codebase on GitHub. Its community spans AI artists, researchers, and model creators worldwide.

Who Civit AI, Inc. competes with, and how they differ.
Hugging Face is a general-purpose open-model hub spanning text, audio, and vision models with enterprise APIs and Spaces hosting, versus Civitai's narrower but deeper focus on Stable Diffusion/Flux checkpoints, LoRAs, and an on-site image/video generator.
1 product reviewed on TopReviewedTensor.Art runs the same checkpoint/LoRA-sharing and on-site generation model as Civitai, including comparable tolerance for mature content, making it the closest like-for-like alternative when either platform tightens moderation.
1 product reviewed on TopReviewedMage Space offers community Stable Diffusion model hosting and on-site generation at smaller scale than Civitai, with a simpler creator-monetization model and no comparable bounty or licensing-fee system.
1 product reviewed on TopReviewedOpenArt centers on curated workflows, templates, and a smaller model library aimed at designers, versus Civitai's open marketplace where any creator can upload and monetize checkpoints and LoRAs.
1 product reviewed on TopReviewedMidjourney is closed-source and accessed via Discord/web app on a flat subscription with no user-uploadable model marketplace, competing for image-generation spend rather than for creator/model-hosting traffic.
1 product reviewed on TopReviewedReplicate is a developer-first API marketplace for running (not browsing or discovering) open models, including many also hosted on Civitai, competing for the builder audience rather than Civitai's hobbyist/creator community.
