What does Paper do?
Paper is a connected design canvas that links teams, agents, code, and data on a single web-standards-based design space, enabling designers to move fluidly from canvas to code and back while collaborating with AI agents. Founded in 2024 by Stephen Haney, co-creator of Radix UI, the company raised a $4.2M seed round in February 2025 led by Accel and Basecase.
