From artifact to insight in under 10 minutes.

No setup. No waiting. You send it, the system simulates.

Step 1

Send what you have

One-liner, landing page, pitch, PRD, or pricing proposal. It does not need to be polished. It needs to be real.

Step 2

Choose who evaluates

Potential customers, investors, builders, competitors, or interest groups. 100 diverse personas per round.

Step 3

Read what they thought

Impact score, objection map, adoption triggers, and response clusters. Compare versions. Iterate with data.

Five perspectives. One simulation.

Each society brings together 100 personas with distinct profiles, motivations, and evaluation criteria. You choose who matters for this round.

Click a society to explore

Customers

Potential users with varied jobs-to-be-done, pains, and adoption criteria.

They reveal whether your value proposition resonates with real needs and buying triggers.

0personas active

Investors

Profiles from angel investors to VCs. They evaluate traction, timing, and return potential.

Their objections surface gaps in your market sizing, defensibility, and unit economics narrative.

Builders

Engineers, designers, and PMs. They challenge technical feasibility and execution clarity.

They stress-test your roadmap and expose misalignment between vision and implementation.

Competitors

Perspective from those already in-market. They expose blind spots in differentiation.

Their reactions highlight where your positioning is vulnerable or your moat is thin.

Interest Groups

Regulators, press, and communities. They detect reputation and large-scale adoption risks.

They anticipate public perception issues and compliance hurdles before they become blockers.

Iterate with evidence, not opinion.

Compare two versions of the same artifact side by side. See exactly where one narrative performs better — and why.

Rafael T., founder solo, marketplace

"I showed it to investors and they asked if I had done user research. I said yes."

Marcos V., founder, fintech early stage
