Feedback from people
Lisa-Jane Perraud, International MSc Programme Director at GEM
"When someone makes something complicated seem simple, it's a sign that they really master the subject. Sergio demonstrated his total understanding of the product management domain when he gave a masterclass to the MSc innovation, strategy and entrepreneurship class (of which he is a senior alumnus). Sergio reached out to suggest the pertinence of training current students on this topic, spent considerable time with us honing his presentation and examples and then gave a seamless presentation. I really appreciate his measured calm and clear communication. I strongly recommend working with Sergio, in whatever capacity - he is an active listener ( rare!) and a generous professional when sharing his expertise. THANK YOU SERGIO"
Simon Flossmann, Professional Scrum Trainer
"If you want to learn the ins and outs of modern product management, then I highly recommend joining one of Sergio's Product Management classes through Product School. Through an intense 8-week-long class, Sergio helped me to deeply understand: Determine a Product Strategy, Identify Opportunities & Acquire Customers, Innovate Opportunities &, Achieve Product-Market Fit, define your Product, Master Design Thinking & Development, Understand Product Marketing & Strategy, and Orchestrate a Successful Product Launch Structure Product Growth in an Organization.
Besides the world-class content of the class materials, Sergio provides tons of real-world stories on how he applies all this knowledge in his day-to-day work at Amazon."

Maneesh Behera, Project Management Intern at Ubisoft
"Sergio has been a mentor and a professor to me during my master's degree at Grenoble Ecole de Management. He is one of the best mentors when it comes to digital product management. He was kind enough to share his experience with me as well was patient enough to discuss mine. However, what I appreciate the most is that he has a very strong hold of the upcoming tech, with an ability to foresee its implementations with existing products. I highly recommend anyone looking for a knowledgeable, patient, innovative and supportive mentor to have a quick discussion about your goals with Sergio, you will realise the wholistic view he has for product management."
Rebeca Cruz, Project Controller Intern at Gaggenau
"Sergio was my professor for the Product Management course at Grenoble École de Management. He is a knowledgeable and experienced professional with a strong background in product management, innovation, and leadership.
During the course, Sergio explained the topics often using real-life examples from his work at Amazon and other companies. We did a final project, where we worked like real Product Managers to improve an app. Sergio guided us through every step of the process, encouraging us to think critically and creatively. He provided constructive feedback, challenged our ideas in a positive way, and always made time to support our progress.
He is not only a good professor but also a supportive mentor who really cares about helping students grow. I recommend him to anyone interested in learning in a hands-on way."

Shalmali Chury, International Marketing and Business Development
"Had the opportunity to be part of Sergio's very first class, and I’m genuinely grateful for the experience. His course unexpectedly sparked a strong interest in product management that I now plan to pursue further. His clear dedication and genuine effort to help us learn stood out. One moment that really stayed with me was when he created a mock app just for our group project — an effort that isnt typically seen. That project pushed us to explore the many dimensions of product management in a practical and engaging way, and I loved every part of it."
