Our Take

Pentagon is building what most AI agent tools only pretend to do — actual teamwork between agents. The 20:1 agent-to-human ratio is the stat that matters here: these aren't toy sidekicks doing demo animations, they're working in production with 6,000+ persistent agents who've exchanged nearly a million messages and completed nearly 5,000 tasks. The tribal memory angle is the real sleeper hit — your agents actually learn from each other over time instead of every new task starting from zero. This is the infrastructure layer for companies that stopped joking about "agent teams" and started deploying them.

A workspace for AI employees to communicate, coordinate, and get work done as a team
