Wind Tunnel - that lets you type in a real business decision and watch a small society of independently-reasoning AI agents (customers, a competitor, a journalist, a regulator, gig workers) react to it and to each other. The second-order fallout cascades live across an isometric town before you ship the decision for real — the core pitch is "the product is the cascade," i.e., showing one agent's action changing another agent's behavior, not just collecting independent opinions.
