Briefs → personas → simulations → real-world testing.

Tesemble runs the exploration stage of GTM in minutes, so the expensive part (talking to real customers) starts from a shorter list.

From hypothesis to experiment in four steps.

Explore many ideas at once. Take the ones that survive to the real world.

  1. 1

    Bring your context

    Start with what you have: your website, a product brief, positioning, landing-page copy or a sales pitch.

  2. 2

    Define your audience

    Describe B2B or B2C buyers by role, industry, company size, geography, buying behaviour, pain points and current alternatives.

  3. 3

    Simulate

    The same message runs across hundreds of profiles. Every run shows who reacted differently, which idea looks stronger, likely objections and a recommended experiment.

  4. 4

    Take the survivors to the real world

    Simulation narrows the search. Real customers decide. Test the strongest ideas with them next.

Outputs

Tesemble doesn't just give you responses. It gives you experiments.

Every simulation ends with something you can act on, not a wall of generated text.

Why not just use Claude or ChatGPT?

A simulation is more than asking an LLM a question 100 times.

You can run the same method yourself. We open-sourced it as icp-gtm-sim: a free skill for Claude, ChatGPT, and Codex that builds a defined audience and reports segment-level patterns.

Tesemble runs that workflow when you need it often — with visual reports, comparisons, and faster runs at scale.
