Test your business idea before you launchYour idea, under pressure.

Write it down: it becomes a block. A Scout checks it against the real market, 3 to 5 experts with opposing interests tear it apart in isolation, a devil's advocate strikes wherever they agree. Whatever holds up gets a stamped verdict.

The more you tell them, the sharper the verdict. Tell them:

  • the product, and who it's for
  • how it makes money
  • the competitors you know of, even indirect ones
  • what you already have (customers, premises, team…) and what makes you hesitate

3 to 5 minutes, live. No free trial, on purpose. See a real verdict

The Scout

First, the real market.

Before anyone gives an opinion, the Scout goes out on the web: competitors, listed prices, complaints from real customers, each with its source. Every finding sticks to your idea.

The Orchestrator

A council picked to disagree.

It reads the dossier and assembles 3 to 5 experts with opposing interests. Not complementary: opposed. The Financier, the Customer's Voice, the Competitor, sometimes the Investor or the Regulator.

The experts

Each on their own side, behind glass.

They analyze in parallel without seeing each other. Nobody falls in line behind whoever speaks first: each one pushes their angle all the way and cites the dossier.

The debate

Then the glass comes down.

They answer each other, contradict each other, push your idea or pull it apart. Every round, each one chooses:

  • holds their ground
  • doubles down
  • concedes

The devil's advocate

It hits where everyone agrees.

Its job: the assumption nobody checked. Played by a different model family, it has no reason to be polite. Whatever sounds hollow cracks and falls off.

The verdict

What holds up gets stamped.

The synthesis takes a side without averaging: for, against or conditional, with the conditions spelled out in black and white.

The stamp only turns to yes if

  • a developer community already exists, and it's measurable: downloads, external PRs, forks;
  • cash covers at least 24 months;
  • the Red Hat model is locked in from day one: 100% open, revenue from support subscriptions.
“Congratulations on your irrevocable clause: it guarantees you'll die open source, loyal and without revenue.”The devil's advocate

Real dossier and verdict from a recorded session on the idea “Take the product open source”. Yours covers your market, with its own sources.

A chatbot answers. A council investigates.

The question everyone asks before paying. Here's the answer, line by line.

Straight questions.

How is this better than free ChatGPT?

ChatGPT wants to please you: one model, no research, it validates almost everything. Here: 3 to 5 experts with opposing interests, real same-day market data, and a devil's advocate played by a different model family.

Why is there no free version?

Free tools flatter you to keep you around. We get paid once, to tell you the truth once. And if a session fails for technical reasons, your credit is restored automatically, refundable on request.

How long does a session take?

3 to 5 minutes, live before your eyes. The Scout does real research: it's the slowest part, and it's what keeps the debate honest.

Where does the dossier data come from?

From the web, at the moment you ask: competitors, listed prices, user reviews and complaints, how long players have been around. Every item keeps its source, and you can browse the dossier during the session.

What's the difference between 1 council and Deliberation?

The €9.99 council plays one round of exchanges. Deliberation, at €30, plays three, with the full transcript: you see who doubles down, who concedes, and why.

What if the council is wrong?

It will be wrong sometimes, like any council. Its job isn't to be right for you: it's to show you the angles you didn't want to look at.

Do my ideas stay confidential?

Your session lives at a private, unguessable address that we never publish or list anywhere. Only you decide to share it. Nothing is resold.

Enough going round in circles.

Put your idea down. The council meets right away, and it won't go easy on you.

The more you tell them, the sharper the verdict. Tell them:

  • the product, and who it's for
  • how it makes money
  • the competitors you know of, even indirect ones
  • what you already have (customers, premises, team…) and what makes you hesitate

Or Deliberation for €30, three rounds of debate.
