Should we raise funding now or bootstrap for another 12 months?
Early-stage investor
Market timing is favorable. Raising €1.2M now gives you 18 months of runway and the ability to build traction without pressure…
Bootstrapped founder
Raising dilutes too early. With your €8k MRR, 12 more months of bootstrap lets you validate product-market fit without external pressure…
Strategic CFO
The real question is your acquisition curve. If CAC < 3 months of LTV, raise now. Otherwise, optimize unit economics first…
What the circle concludes"The consensus leans toward 6 more months of bootstrap — unless a partnership opportunity changes the equation."

Three AIs. One circle. Better decisions.

How it works

Three steps.
Total clarity.

No generic chatbot. A structured process that forces you to consider angles you would have ignored.

01
Ask your question
The circle analyzes your question and automatically generates tailored expert roles — with the right friction and the right diverging perspectives.
02
The debate begins
Claude, ChatGPT and Gemini embody each expert. They argue, clash, and respond. Up to 5 progressive argumentation cycles.
03
The synthesis decides
Argument scores, convergences, tensions, concrete recommendations and final verdict. The circle deliberates — you decide with the full picture.
Optimistic expert
B2B SaaS market growth is +28% this year. Your positioning aligns with a favorable macro. Raising now capitalizes on the window…
Risk analyst
The 4.2% monthly churn is the real problem. Raising in these conditions means filling a leaky bucket with other people's money…
Strategic CFO
At €8k MRR, the effort/dilution ratio leans toward 6 more months of traction before raising at a better valuation…
What the circle concludes"Reduce churn to 2% before raising. The investor will pay more in 4 months."
Score: 8.4/10

Pourquoi Plurall

What your brain
alone cannot do.

Overcome your cognitive biases
Each AI embodies a distinct perspective and argues it to the end. You hear the objections you would have ignored yourself.
A real debate, not a summary
The AIs respond, rebut and concede. The result is a structured intellectual confrontation — not a list of bullet points.
Configurable experts
Decision-maker, Senior expert, Contributor. Optimistic, pessimistic, neutral stance. You control the weight of each voice in the final synthesis.
Features

Everything you need
to decide better.

Designed for important decisions — not for questions Google can answer.

AI-generated roles
Claude analyzes your question and automatically suggests the most relevant expert roles — with naturally diverging perspectives.
Up to 5 debate cycles
Readings → Friction → Recalibration → Edge → Clarity. Each cycle deepens the analysis and forces concessions.
Expert configuration
Hierarchy (Contributor / Senior expert / Decision-maker) and stance (Very critical → Enthusiastic). The circle adapts to your exact context.
Visual synthesis
Argument scores per expert, convergences, tensions, debate evolution, actionable recommendations and final verdict. At a glance.
Custom experts
Add any role the circle wouldn't have suggested. "My skeptical lawyer", "The unhappy customer", "The aggressive competitor".
Past consultations
All your consultations are saved and indexed. Resume a debate, compare decisions, track the evolution of your thinking.
Témoignages

What the circle
has changed.

I had decided to hire a COO. After Plurall, I realized that was the wrong problem — I needed a head of sales. 6 months later, MRR x3.
ML
Marc L.
Founder, B2B SaaS · Series A
The pessimistic expert raised an objection that neither my partners nor my board had seen. We avoided a pricing mistake that would have cost us 40% of CAC.
AS
Amélie S.
CPO · Fintech scale-up
I use it before every important negotiation. The "Friction" cycle is particularly brutal — exactly what you need to not get caught off guard.
TM
Thomas M.
Partner · Early-stage VC fund
In 20 minutes, I got an analysis that would have taken my team 3 days to produce — and probably less complete. Expert configuration changes everything.
JB
Julie B.
Strategy Director · €200M company
What I was missing wasn't more data — it was someone who truly challenges me. Plurall does that with a rigor no consultant can maintain.

FAQ

Everything you
want to know.

What's the difference from using ChatGPT or Claude directly?+
Asking an AI a question gives you one opinion. Plurall structures a debate between contradictory perspectives — the AIs clash, respond to each other and must defend their position. The result is incomparably richer and more honest about uncertainties.
Can I change plans?+
Yes, at any time. Changes take effect immediately. Upgrading unlocks new features instantly. Downgrading takes effect at the end of your billing period.
What happens when I reach my debate quota?+
You receive a notification at 80% of your quota. You can upgrade immediately or wait for the monthly reset. On Free, the 10 debates are a one-time allocation — upgrade to continue.
Are prices in USD?+
Yes. Stripe handles currency conversion automatically based on your country. VAT may apply depending on your location.
Is there a Team plan?+
A Team plan (5 seats, shared debates) is in preparation. Join the waitlist to be notified at launch.
Is my data confidential?+
Your consultations are stored in your personal space and never shared. They are not used to train the models. You can delete all your data from settings at any time.
