Marketing Principle

There is no magic recipe that suits all! Every project and every client are unique. To reach the maximum potential aim, marketing planning should be based on research, monitoring, analysis and key interventions. 

Design Philosophy

The Essence of Our Design Philosophy in a Socrates – Adeimantus dialogue as expressed by Plato in 360BCE

“Then beauty of style and harmony and grace and good rhythm depend on simplicity, –I mean the true simplicity of a rightly and nobly ordered mind and character, not that other simplicity which is only an euphemism for folly? 

Very true, he replied. 

And if our youth are to do their work in life, must they not make these graces and harmonies their perpetual aim? 

They must. 

And surely the art of the painter and every other creative and constructive art are full of them, –weaving, embroidery, architecture, and every kind of manufacture; also nature, animal and vegetable, –in all of them there is grace or the absence of grace. And ugliness and discord and inharmonious motion are nearly allied to ill words and ill nature, as grace and harmony are the twin sisters of goodness and virtue and bear their likeness.”

Plato, “The Republic, book III”, 360 B.C.E
