03The method
How we vet an idea
The problem is paid for today
Someone already spends money or time working around it.
The market can be counted
We know how many people or companies are affected in France, and where the number comes from.
Three competitors, three weaknesses
If there is nobody, there is often nothing to take.
A member built it
The score rises when a build shipped and reported its numbers.
