ComfyUI raises $30M at $500M valuation for AI media control

ComfyUI, a startup that provides a node-based approach for managing diffusion model outputs, has successfully secured $30 million in funding, achieving a valuation of $500 million. This funding round was spearheaded by Craft Ventures, with contributions from Pace Capital, Chemistry, and TruArrow. Established as an open-source initiative in 2023, ComfyUI quickly became popular among creatives for its detailed control over generating images, videos, and audio. In late 2024, the company raised $19 million in Series A funding from Chemistry Ventures, Cursor Capital, and Guillermo Rauch. CEO Yoland Yan highlights ComfyUI's accuracy compared to prompt-based platforms like Midjourney, which he claims only achieve 60-80% of the intended outcomes. The platform now boasts over 4 million users, with growing job listings for 'ComfyUI artist or engineer.' Competitors include Weavy, which was acquired by Figma in 2025.
