The story
tldraw began as an open-source collaborative whiteboard released by developer Steve Ruiz around 2021, which was rewritten and turned into a venture-backed company in 2022 offering a React-based infinite canvas SDK for developers. It gained wide attention in late 2023 for its viral 'Make Real' AI demo built around OpenAI's GPT-4 Vision. It now sells the tldraw SDK commercially to companies while keeping the tldraw.com whiteboard free, and has raised roughly $14.7M from Lux Capital, Amplify Partners and Definition Capital.
