ComfyUI raises $30 million at $500 million valuation as creators adopt node-based AI control tools

ComfyUI, a startup offering node-based control over AI image, video, and audio generation, closed a $30 million funding round at a $500 million valuation. The round was led by Craft Ventures, with participation from Pace Capital, Chemistry, and TruArrow, according to TechCrunch reporting.

The platform evolved from an open-source project launched in 2023 to address the precision limitations of diffusion models like Midjourney and DALL-E. Rather than relying on prompts, ComfyUI's interface lets creators link specific components of the generation pipeline, enabling granular control over outputs at each step. Co-founder Yoland Yan described prompt-based generation as reaching only 60–80% accuracy, after which small refinement requests can overwrite correct elements entirely.

ComfyUI claims over 4 million users across visual effects, animation, advertising, and industrial design. The tool has gained enough adoption that studios increasingly list 'ComfyUI artist' or 'ComfyUI engineer' as formal job titles. The company previously raised $19 million in Series A funding in late 2024 from Chemistry Ventures, Cursor Capital, and Vercel founder Guillermo Rauch.

Yan argued that as AI-generated content becomes ubiquitous, human-in-the-loop approaches offering precise control will dominate professional creative markets over lower-control alternatives, even as underlying models continue to improve.
