Simulate Thousands
of Possible Futures

Stacle is an AI launch simulation platform that predicts how a product launch, campaign, or announcement will land before it ships. It populates thousands of parallel worlds with multi-agent AI personas — journalists, investors, customers, and skeptics — then runs your launch through all of them and reports the distribution of outcomes rather than a single forecast.

A Stacle run moves through four stages: brief, signal, simulated, and decide. You submit a deck, URL, or one-line idea; Stacle pulls live intel from ten public sources to calibrate priors; it spins up a synthetic world of agents with their own memory and motives; and it returns outcome distributions, counter-narratives, and a decision memo across 1,024 branching futures. See the three-step walkthrough.

A parallel-world launch simulation runs the same launch thousands of times under varied conditions and records how often each outcome occurs. Instead of one prediction, you get a probability distribution — how likely the launch is to be covered, ignored, or attacked — which is what makes the result plannable rather than a single guess that is either right or wrong.

Traditional market research samples a few dozen real people once and takes weeks; Stacle simulates thousands of calibrated synthetic audiences in under five minutes and can be re-run every time the plan changes. Because a run is cheap and fast, Stacle is used iteratively — to compare messaging options and rehearse objections — rather than as a single go/no-go study.

Stacle anchors every agent in live public signal rather than model imagination. Each world is calibrated against ten sources — search interest, news coverage, community discussion, competitor moves, and customer voices — so agent behaviour reflects what audiences are actually doing at the time of the run.

A Stacle run goes from brief to outcome in under five minutes, with no analysts in the loop and no setup required. You drop in a deck, a URL, or a one-line description and the first synthetic world is ready to inspect immediately.

Stacle simulates product launches, marketing campaigns, pricing changes, funding and company announcements, positioning and messaging tests, and crisis or backlash scenarios. Any decision that will meet a public audience can be rehearsed as a synthetic world before it is made.

Yes. Stacle runs private by default: strategy inputs stay inside your perimeter, deployments are single-tenant, and a private model option is available for launches that cannot be exposed to third-party inference. Read the full security practices.
