“Lenny and I worked on a day-to-day basis for a duration of 2 months, and I enjoyed working with him every step of the line. Working on this project, Lenny showed a perfect mix of both soft and hard skills. He knew when to challenge me and always highlighted his points with concrete examples. He is a true specialist in his field, always bringing the right insights when needed. This was a pleasant experience both on a professional and a personal level.”

“I had the pleasure of having Lenny as my mentor for my final field project of Solvay Brussels School. During these 6 weeks, he didn't only teach us a lot about growth hacking, he also taught us to question everything, view things from different perspectives and this while continuously motivating us.What I appreciated most while working with Lenny, was that he treated us, students, as an equal at every given moment and always took the time to listen to our ideas and views.Every morning, over a coffee, he asked us 3 simple questions: What did you achieve yesterday? What is your plan for today? What is stopping you from achieving your goal? These questions made us reflect about ourselves and about the process of our project.Anyone would be lucky to have Lenny as his or her mentor and to work together with him!”
