I.The Forum
Where personas convene
Layo opens a live forum the moment a brief lands. Two hundred personas, soon thousands, file in by segment.
Run the launch before you build it.
Shipping a feature is still mostly guesswork. The Product Manager writes the brief, the team builds it, and the company only finds out how customers react after launch, when the damage is already done.
We thought guessing was a problem worth solving.
The Method · in four rooms
How a launch is rehearsed.
The simulation runs in minutes, not weeks. The PM stays in the chair: scrolling threads, pulling on the loudest argument, finding the objection nobody on the team thought to ask.

II.The Witnesses
Built from your evidence
Each persona is distilled from your tickets, calls, NPS, app reviews. Not invented from a generic survey panel.
“Power users will hide this behind a toggle.”
“Segment C will churn before they understand it.”
“The previous version solved a job this drops.”
III.The Trial
Argument, not approval
They debate in public. Replies, upvotes, churn warnings, segment splits. The loudest critic is the one you click first.

IV.The Verdict
A change you can ship
What leaves the room is a transcript and a single decision: copy change, rollout condition, kill signal, by Tuesday.
§ The team
The founding team.
We met at hackathons in Zürich and Munich.
Bring us a feature you need fast feedback on.
We are pairing with product teams who have real customer data and a decision that cannot wait three weeks for another research cycle.
