Founded as an open-source project in 2023, ComfyUI developed a modular, node-based interface that lets creators control each step of generation from diffusion models for image, video, and audio. The tool has been adopted by creative professionals and technical artists, with the company reporting over 4 million users and usage across visual effects, animation, advertising, and industrial design. ComfyUI evolved from a community project into a formal startup and has raised multiple rounds, including $19 million in a late‑2024 Series A and the recent $30 million round at a $500 million valuation. Yoland Yan is the company’s co-founder and CEO and has emphasized the platform’s role in enabling precise, human-in-the-loop adjustments that prompting alone often cannot deliver. The company faces competitors in adjacent tooling, including Weavy, which was acquired by Figma.
