To have someone you can trust and rely on is asking a lot these days, and Sergio and the company he represents is just that. It values a job well done, punctuality, honesty and a friendly and approachable manner. A pleasure to work with him. I will follow him in all your professional endeavours...

José Manuel Hernando

Since I met Sergio we have always had a very direct, one-to-one relationship. He is a born entrepreneur, highly intelligent, organised and as knowledgeable about the business as anyone. It is always devising new services to provide a solution to customers' problems. He has a taste for design and knows how to appreciate it, which is fundamental.

I like company directors who sell, and who go the extra mile for their customers. Every time I talk to Sergio, he transmits commitment, dedication and a great eagerness to help his clients: he is a resolute person, and he never stops training himself to improve as a professional and boost his business. With people like Sergio you can trust in any kind of project because you know it will always go ahead.

Sergio is one of the most committed and hard-working people I have ever had the opportunity to work with; Always looking at the positive side of things, he is capable of taking forward any project he proposes, getting all team members enthusiastic and involved. In addition to being a great person, very empathetic and approachable, he is a student of new trends (especially digital) and an "early adopter" of all the techniques and products that allow him to learn how to improve, in order to teach how to improve. It has been, and I hope it will continue to be in the future, a pleasure to be able to collaborate with him on the technological side of some of his projects, and to be able to learn from someone who has such a complete business vision. Undoubtedly, the best partner for any future project.

In my more than 30 years of business experience, I have come across few minds as sharp as Sergio Carbonell's. He is a man with an enormous knowledge of new technologies from the point of view that is of most interest to a company, that is to say, the practical, the real and direct, the one that produces results. From my point of view, he is a gifted man in this field. As far as I know of my professional relationship with him, he has always fulfilled to perfection in those issues that we have dealt with together, demonstrating a great knowledge of the sector and the profession, as well as great seriousness and professionalism.

It is very easy to recommend Sergio: in 100% of the projects in which, for one reason or another, we have worked together, his involvement has been absolute. With total dedication and commitment, he has shown me a track record and ethics that are out of the ordinary.
