ComfyUI, a startup that gives creators granular control over AI-generated images, video, and audio, raised a $30 million funding round in 2026 at a $500 million valuation. The round was led by Craft Ventures, with participation from Pace Capital, Chemistry, and TruArrow.
The company began as an open-source project in 2023, developed to address the limitations of early diffusion models. At the time, tools like Midjourney and OpenAI’s DALL-E frequently produced errors — such as adding extra fingers to hands — and offered users little ability to fix specific details without disrupting the rest of an output. ComfyUI’s founders responded by building a modular, node-based framework that lets creators control each individual step of the generation process.
The project grew into a formal startup and in late 2024 closed a $19 million Series A from investors including Chemistry Ventures, Cursor Capital, and Guillermo Rauch, founder of Vercel. The latest round marks a significant step up in valuation.
Co-founder and CEO Yoland Yan described the core problem with standard prompt-based tools. “If you think about your typical prompt-based solution, like Midjourney or ChatGPT, you ask for something, it [gets only] 60%–80% there,” Yan told TechCrunch. “But to change that remaining 20%, you have to try this slot machine.” He compared the process to a casino, where prompting a model to make a small adjustment can overwrite parts of an output that were already correct.
ComfyUI’s node-based interface addresses this by letting users link specific components of the generation process independently. The company says it now has over 4 million users, including creative professionals working in visual effects, animation, advertising, and industrial design. The startup notes that “ComfyUI artist or engineer” has begun appearing as a listed job title on studio job boards.
Yan argued that even as foundational AI models continue to improve, demand for precise human control over outputs will remain strong. “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.
