The six factories and their four layers

Brand
They get to know and trust you, before they are buying
Client acquisition
They buy, from the moment someone is buying to the signature
Value delivery
They get the result and stay, from the signature to renewal
Value creation
What we make, whatever its type: software, a service or a course
People
Employees, fractionals, freelancers and AI agents, counted as one workforce
Finance
The money and the rules
