Too expensive for students.

Margins look promising.

Decision score0/100
Type your own idea, then hit Simulate.
One decision. The panel disagrees.
This is the product — specialists arguing against each other so you see every side.
Should we raise prices, or introduce freemium?
Investor
“Raise prices. Demand supports it.”
vs
Customer
“Prices are already too high.”
Growth Specialist
“Introduce a freemium plan.”
vs
Finance Specialist
“Freemium will damage margins.”
They don't agree — and that's exactly what you need before you commit.
One decision. A whole team behind it.
Every run orchestrates a panel of specialists, each pushing from their own angle.

Sample report71/100
Decision: Launch a premium subscription tier for a note-taking app that currently has one free plan.
Competitive analysis
Customer
Free users tolerate ads, but power users want offline access and more storage.
Competitor analyst
Two direct competitors charge $8 and $12 monthly. Bundling offline plus unlimited notes wins.
Pricing strategist
A single $9 tier is cleaner than three. Anchor it against the $12 competitor.
Market opportunities
- Annual billing improves cash flow and locks in early adopters.
- A founding-member price can convert waitlist signups now.
Risk assessment
- Churn if the free tier loses features users already rely on.
- A competitor undercuts the launch price within one quarter.
Action plan
- Bundle offline access with unlimited notes; price it against the $12 competitor.
- Set a clear usage ceiling on the free plan before announcing the paid tier.
- Offer 20% off annual at launch to lock in early adopters.
- Open a founding-member price to convert waitlist signups now.
