The 7-layer sieve

Every idea goes through a structured 7-layer framework, from the hardest physical constraints up to human abstraction, then back down to a concrete product. The order matters: it lets you fail early on what won't hold, and build a solid judgment layer by layer.

1. Physical

Does the idea obey the laws of physics? Energy, matter, biology — we start with what can't be negotiated.

2. Technological

Does the tech exist or does it need to be built? We assess maturity, dependencies, and R&D cost.

3. Legal

Is the idea legal? Regulatory grey areas, existing patents, future regulation risks.

4. Social

What happens if the idea succeeds at scale? Uberization, resistance, cultural acceptability.

5. Psychological

How does the idea affect the individual? Attention, autonomy, dependency, cognition, rebound effects.

6. Economic

Is the idea profitable? R&D costs, acquisition, scale costs. Existing market or new? Revenue model.

7. Product

What concrete form to deliver the idea? Target, channel, pricing, differentiation. Only if the first 6 layers hold.

#10 — Concept physiquement réalisable, technologiquement accessible en série, mais jur

Concept physiquement réalisable, technologiquement accessible en série, mais juridiquement critique sans montage associatif/préfectoral préalable. Le séquençage hôtel/festival → solidarité est la stratégie la plus crédible. Le verrou principal reste économique : la version solidarité n'a pas de modèle de revenus autonome et dépend entièrement du succès de la version hôtel et des subventions publiques.

#9 — Regenerative Immersion Tank for Severe Burns

A full-body immersion device delivering growth factors, antibiotics, and electrical stimulation via lipid vesicles to accelerate tissue regeneration in severe burn patients.

7.1 /10

#8 — A legally sound, technically simple mystery-shopping subscription for independen

A legally sound, technically simple mystery-shopping subscription for independent restaurants. Core risk is unit economics: €79/month leaves razor-thin margins after shopper costs, requiring rapid volume or a price increase to survive. Operationally, building a reliable shopper network city-by-city before scaling sales is the critical execution challenge.
