Open-source platform ComfyUI raises $30M at a $500M a valuation

ComfyUI, the open-source platform that gives creators granular control over AI-generated images, video, and audio, has raised $30 million at a $500 million valuation, bringing total funding to $47 million. The round was led by Craft Ventures with participation from Pace Capital, Chemistry, and TruArrow.

What began in 2023 as a single developer's open-source project addressing limitations in early diffusion models like Midjourney and DALL-E has evolved into the creative industry's leading AI workflow tool. ComfyUI now serves over 4 million users with 150,000+ daily downloads and a community-built library of 60,000+ custom nodes.

Unlike prompt-based tools where small changes can unpredictably alter entire outputs, ComfyUI's node-based interface allows creators to link specific components of the generation process. "If you think about your typical prompt-based solution, you ask for something, it gets only 60-80% there," said co-founder and CEO Yoland Yan. "But to change that remaining 20%, you have to try this slot machine."

The platform has become essential infrastructure for production studios, agencies, and corporate creative teams. Silverside AI used ComfyUI to produce SVEDKA's AI-generated Super Bowl advertisement, while studios like Black Math employ it to build modular pipelines integrating motion, texture, and generative tools. ComfyUI's impact has been so substantial that "ComfyUI artist or engineer" has started appearing as a dedicated job title on studio boards.

The funding will expand Comfy Cloud for team collaboration, enhance local deployment stability, and strengthen infrastructure for the platform's 60,000+ community nodes—all while maintaining the project's open-source foundation.

"We pledge: ComfyUI remains perpetually open," the team stated. "You'll always retain full access to self-hosted deployments with complete control over your creations."
