Launch scenario

What decisions do you want to test?

A sandbox for decision-making.

Polyhyle is a simulation platform where teams create a controlled world, define its assumptions, populate it with synthetic humans, and run strategic scenarios before taking real-world action.

Every run comes back structured.

Each simulation type returns its own output: metrics, distributions, segment breakdowns and the reasoning behind every answer. The panels below use sample data.

HOW IT WORKS

See how decisions play out before the market does.

Model the world, simulate behavior, and compare likely outcomes before launch.

  1. 01

    Build the world

    Set assumptions, market conditions, and constraints.

  2. 02

    Simulate behavior

    Populate it with synthetic humans and run realistic scenarios.

  3. 03

    Compare outcomes

    See likely reactions across segments before going live.

  4. 04

    Decide before launch

    Choose the strongest direction with less exposure and faster feedback.

Plugs into your stack.

Polyhyle connects to the analytics and product tools you already use, so every simulation is grounded in how your real users actually behave.

Questions before you simulate.

A quick guide to who Polyhyle is for, what it solves, and where it fits into your decision workflow.

Who is Polyhyle for?

Polyhyle is for product, growth, research, strategy, and founder teams that need to make consequential decisions before they have enough live signal.

What problem does Polyhyle solve?

It reduces the gap between an idea and real-world feedback. Instead of waiting weeks for interviews, tests, or enough traffic, teams can simulate likely reactions before committing budget, code, or reputation.

What can we simulate?

You can test pricing changes, copy and positioning, funnel updates, onboarding flows, market shocks, competitor moves, rollout strategies, and willingness-to-pay assumptions.

How is this different from A/B testing?

A/B tests require live exposure and enough traffic. Polyhyle runs before launch, so you can compare options and remove weak directions before users ever see them.

How reliable are simulated outcomes?

Polyhyle is decision support, not a guarantee. Results depend on the world, assumptions, and scenario you configure, and they are strongest when used to compare directions rather than predict a single exact number.

What inputs do we need to start?

You can start with a market, audience segments, the decision you want to test, and the assumptions that might shape behavior. More context improves the simulation, but you do not need a full research dossier.

When should a team use Polyhyle?

Use it before a launch, price change, campaign, onboarding update, market entry, or any decision where learning only after exposure would be slow, expensive, or risky.

Can it work for early-stage teams?

Yes. Early teams can use Polyhyle to explore positioning, pricing, and target segments before they have large datasets or enough traffic for conventional experiments.

How do I get started?

Log in to Polyhyle, build your first world, populate it with synthetic humans, and run a scenario. You can go from setup to your first simulated outcome in minutes.
