In architecture, it has served as a grounding for many strengths and talisman of protection, in nature it is linked to the growth of things, whilst for the Pythagoreans it symbolises harmony and balance. And, above all, it is the symbol of the complete human being.


On this basis of values (pentagon) our business model "BAYLOS 5.0", is identified wholly by innovation, to be able to generate value to our clients and thus furnish them with the best service.
