For several years he devoted himself to teach with enthusiasm what he had learned with dedication, but he soon realized that the university air would not blow with enough force to change the world and he decided to try it in the financial markets, which at that time were catching up, like so many other things in the Spain of the late 80's. In the financial markets he found impossible explanations, unacceptable characters and very interesting personalities.
He also learned that the first independence is economic and he focused on what he could achieve. He participated intensively in all corners of the financial markets, as an investor and as an issuer and was a professor at Business Schools.

During the period in Telefónica (2002-2016) he participated in all the operations of that stage, which were many and large. In those years he learned that the tools of number sculptors do not improve the quality of the material with which they work. And now he is an entrepreneur and practices entrepreneurship. In Spain he learns and in Brazil he undertakes, trying to cultivate both hemispheres (of the brain) with incomprehensibly positive results.
In his less public life, he has been reprimanded by the same woman for four decades and has been surprised by three children who have managed to direct the course when the fog was thicker. If life handed out letters, Santiago got the aces. If he was born again, you will learn to navigate earlier and better.
