ComfyUI, a startup that gives creators granular control over AI-generated images, video, and audio, raised $30 million in April 2026 at a $500 million valuation. The round was led by Craft Ventures, with participation from Pace Capital, Chemistry, and TruArrow.
The company’s node-based interface lets users link specific components of the AI generation process rather than relying on open-ended text prompts. ComfyUI says it has over 4 million users and is used by creative professionals across visual effects, animation, advertising, and industrial design. The job title “ComfyUI artist or engineer” has reportedly begun appearing on studio job boards.
ComfyUI began as an open-source project in 2023, developed in response to the limitations of early diffusion models. It previously raised $19 million in a Series A round in late 2024 from investors including Chemistry Ventures, Cursor Capital, and Guillermo Rauch, founder of Vercel.
Co-founder and CEO Yoland Yan described the shortcoming of standard prompt-based tools in an interview with TechCrunch. “If you think about your typical prompt-based solution, like Midjourney or ChatGPT, you ask for something, it [gets only] 60%–80% there,” Yan said. “But to change that remaining 20%, you have to try this slot machine.” He noted that prompting a model to make a small adjustment can overwrite parts of the output that were already correct.
Yan argued that demand for precise, human-directed AI tools will persist even as foundational models improve. “In the world where AI slop is going to be everywhere, the Comfy version of human-in-the-loop approach is going to win out most of the eyeballs in the end,” he said. ComfyUI’s competitors include Weavy, a startup acquired by Figma last year.
