Mosaic on the record

What they shipped

  • From its YC profile: Mosaic gives teams and their coding agents shared memory across every session, so everyone can understand what happened, why decisions were made, and pick up where someone else left off. We started as a real-time coding environment where multiple people and their agents can work together live. It went viral, defined the multiplayer AI category, and inspired frontier labs like Anthropic. Together, we’re building the infrastructure for people and agents to share context and work together.

  • Its own site describes it as: "Mosaic puts every AI coding session your team runs — Claude Code, Codex, Cursor, and 11 more — into one shared, read-only drive." (source)

Who is behind it

  • Dorsa Rohani, Founder: Co-Founder @ Mosaic | NVIDIA, University of Toronto (source)
