Monumental Labs builds an AI design agent that generates UI designs, websites, and marketing materials from text descriptions, sketches, or screenshots. The platform automates iterative design tasks, allowing users to edit and refine outputs conversationally. It serves product designers, marketers, and no-code builders aiming to prototype faster without deep design expertise. Customers include individual creators and small teams integrating with Figma and other tools. Founded in 2023 in New York by Micah Springut, previously at Meta and Scale AI. The company emerged from stealth with seed funding in 2024.
