The run

From One-Line Idea to
A Future You Can See.

Every Stacle run moves through four stages — brief, signal, simulate, decide. You bring the question. We synthesize the world.

Brief

01 — Brief

Drop a pitch deck, a website, or a one-line idea. Stacle reads it, extracts the offer, the audience, the wedge — and builds a profile of your business.

02 — Signal

We pull live intel from ten public sources — search trends, news, communities, competitor moves, customer voices — and turn them into priors your world is calibrated against.

03 — Simulate

Stacle spins up a world of synthetic agents — protagonists, crowd, NPCs — each with their own memory and motives. Press go, and watch the timeline run in fast-forward.

04 — Decide

See the headline you'll get, the backlash you'll absorb, the coverage curve you'll ride — across thousands of possible futures. Then choose the one you actually want.

How it works

From Idea to Possible Future

Three steps between you and a synthetic world that simulates how your launch, campaign, or announcement will actually land.

Step 01

Describe

Drop your pitch, deck, or website. Stacle reads it, extracts the offer, the audience, and the angle — and builds a calibrated profile of your business in seconds.

Step 02

Populate

Stacle synthesizes a world of agents — investors, journalists, customers, skeptics, lurkers — modelled on real public data and tuned to the audience that matters for you.

Step 03

Run

Press go. The timeline unfolds in real time, branches into thousands of alternate futures, and surfaces the headlines, backlash, and quiet wins you'd actually face on launch day.

Calibrated to Reality

Plugged Into The Real World

Stacle reads the same internet your buyers do. Frontier LLMs power the agents. Real-world signal sources — search, news, communities, competitor moves — keep every world calibrated. Then the decisions flow back to the tools your team already lives in.

Stacle is powered by frontier LLMs (OpenAI, Anthropic, Google Gemini, Groq) and reads live signal from Reddit, X, Hacker News, YouTube, Product Hunt, Google News, Wikipedia, and Google Trends. Outputs sync to Salesforce, HubSpot, Zapier, Slack, Notion, and GitHub. Runs on AWS, Google Cloud, and Microsoft Azure with MongoDB, Redis, and Docker on the infrastructure side.

Why Stacle

Built to Predict Launches, Not Just Power Demos.

Calibrated to Reality

Agents are anchored in live signal — search interest, news coverage, competitor mentions, community sentiment. Your worlds run on what people actually do, not vibes.

Forward-deployed Sims

Stacle's team stands up your first ten worlds with you. Production-grade scenarios, real audiences, real numbers — not toy demos with two agents in a sandbox.

Branching Futures

Every run forks into thousands of possible futures. You see distributions, not point estimates — probabilities you can plan a launch around.

Counter-Narrative Detection

Surface the criticism before launch day. The exact angle a journalist will take. The comment that'll go viral. The objection your buyers will keep typing.

Private by Default

Your strategy never leaves your perimeter. SOC 2, single-tenant, with a private model option for the launches you can't afford to leak.

TODAY
