How it works

What happens afteryou press run.

One real run, backstage and start to finish: our own ad against a buzzword version of it, 30 people, 2 minutes 25 seconds, 16 credits. Every number on this page comes from that run.

Run 508c1fb2, on its real clock (played ten times faster)Each dot is one persona, at the second it answered

1You drop it in

Two versions of one line.One room to judge both.

An ad, a page, a price, an email or an idea, as text or an image. Give it two versions and the same people judge both, so the winner isn't down to who happened to be in the room.

2The room is cast

Nobody is scraped.Everyone is built.

Each seat is assembled from an archetype, a city, a budget, the proof it needs, how it takes risk, how it talks. These are the 30 from this run. Pick anyone.

CastingFrom 101 archetypes, 9 voice axes, 8 decision traits

3Everyone reads alone

Thirty booths.No peeking.

Each persona reads your work in its own call and never sees another's answer, so one loud voice can't tip the room. The booths light up at the second each one answered. Tap one to read it.

Version AFirst answer at 6.2 s, last at 53.6 s

4The same people read B

Same room, second version.They remember the first.

Then the same thirty read version B. 28 answered. Each line below is one person, from where they stood on A to where they landed on B.

A on the left, B on the rightColour is the stance on B

5The objections are counted

Complaints, groupedand counted per version.

Every answer names what's wrong in its own words. We group the ones that mean the same thing and count who raised each, on A and on B.

6You get the call

Keep, fix or kill.With what to change.

Each version gets a score out of 100, a call, the reason, and the fixes the room's objections point to, ranked by impact.

7Then push harder

A call is where it starts.Take it further.

These are synthetic personas, not real customers, and the room doesn't forecast your numbers. It shows you where strangers push back, and why, before they get the chance. Then go talk to real people.

Your turn

Two minutes backstagebeats a month of guessing.

10 free credits when you sign up, no card. Enough for a room of 50.
