Mosaic GTM brain

Mosaic syncs AI coding sessions into shared memory for software teams and their coding agents.

Shared memory for coding agents

market profile

  • text: As developers use multiple coding agents, session context becomes fragmented across tools, people and tasks.
  • text: Shared session memory overlaps with emerging live agent collaboration and orchestration products, though they solve different parts of the workflow.

personas

  • title: Software engineer using coding agents
    pains:
    • Reconstructing a teammate's prior agent work before continuing a task
    • Repeating experiments because past sessions are invisible
  • title: Engineering manager
    pains:
    • Losing the reasoning behind code decisions across individual agent sessions
    • Coordinating handoffs when each developer uses a different agent
  • title: Developer productivity lead
    pains:
    • Building brittle custom glue to share context between agents
    • Supporting a mixed coding-agent toolchain across a team

icp

  • text: Software engineering teams where several developers already use coding agents such as Claude Code, Codex or Cursor.
  • text: Teams with frequent shared code ownership and agent handoffs; company size is not specified.

message pillars

  • text: Bring team coding sessions into one shared location.
  • text: Preserve the history of decisions across agents and teammates.
  • text: Let others continue a session without recreating context.

objections

  • objection: Our team uses several different coding agents.
    response: The launch lists Claude Code, Codex and Cursor; check current support for the exact tools your team uses.
  • objection: Will shared sessions expose sensitive code or prompts?
    response: Review current access controls, retention and security terms with Mosaic before syncing production work.
  • objection: Why not share notes or links manually?
    response: Pilot the sync on a real handoff and compare time spent reconstructing the decisions and work already attempted.
