ComfyUI, a startup that gives creators detailed control over AI-generated images, video, and audio, announced in April 2026 that it has raised $30 million in a new funding round 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 solely on text prompts. Co-founder and CEO Yoland Yan described the limitation of prompt-only tools: “If you think about your typical prompt-based solution, like Midjourney or ChatGPT, you ask for something, it [gets only] 60%–80% there. But to change that remaining 20%, you have to try this slot machine.” He compared the experience to a casino, where prompting a model to make a small adjustment can overwrite parts of an output that were already satisfactory.
ComfyUI started as an open-source project in 2023, shortly after diffusion models emerged, and grew into a formal startup as adoption spread among creative professionals. In late 2024, the company raised $19 million in Series A financing from Chemistry Ventures, Cursor Capital, and Guillermo Rauch, founder of Vercel. The startup now claims more than 4 million users and says its tool is used across visual effects, animation, advertising, and industrial design. The job title “ComfyUI artist or engineer” has reportedly begun appearing on studio job boards.
Yan argued that even as foundational AI models improve, demand for precise, human-guided control will persist. “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.
