"With Martin and his team, during collaborative work and discussions, you will experience numerous 'aha' moments that will help you improve both professionally and personally. Martin seamlessly combines insight and humanity with vast experiences in top-level management, making him an excellent leader, coach, and mentor."

"We invited representatives from SINLEI to address the topic of psychological safety in innovation management. The entire training in this area included an interactive survey among our managers, revealing insights into how managers feel in the decision-making process, presenting new ideas, and other situations. At ORLEN Unipetrol, we aim to establish a corporate culture based on the values of open communication and collaboration. We encourage our employees to come up with new ideas and contribute to changes within the company. SINLEI's workshops were part of a larger project designed to understand and align with our 2030 strategy. The workshops were conducted both online and in-person for over 200 managers, and we appreciate SINLEI's support and their overall highly professional approach. We can recommend Martin and his colleagues as speakers."

"Martin is truly an outstanding mentor and coach who excels in working with groups and skillfully developing motivation, knowledge, and success."

"The innovation workshop with Martin focused on Design Thinking and the creation of new products was truly enriching. We learned to think and ask questions differently, actively listen to customer needs, and avoid getting stuck in our assumptions. Plus, it was fun! Martin is an inspirational instructor, and I highly recommend him"

"Our financial leadership team participated in the VUCA training organized by SINLEI. The training provided significant added value for our development in these challenging times. We realized how this approach will help us in our daily work and what changes we can achieve with our clients through a new mindset. Thanks again to the whole team!"

"Martin was a guest at our leadership conference. His presentation was inspiring and entertaining. He can combine personal managerial experience with stories from current practices across industries, and deliver this mix in a clear, understandable, and vivid manner."

"I approached SINLEI with a request for a keynote on change – how to approach it, what to be mindful of, and what to watch out for. The keynote was tailored for a business unit facing a significant change in their work approach. The lecture was excellent, and I received very positive feedback from the audience. I particularly appreciate the level of interaction, and as a pleasant bonus, I received credible feedback regarding psychological safety in the team."

"SINLEI's workshops were filled with energy, humor, and specific examples that provided us with the necessary motivation for implementing these principles into practice."

"Martin consistently helps us facilitate 'team topics,' such as adapting our local vision and mission to make them relevant to us. The workshop on team dynamics using the CliftonStrengths methodology was particularly well-received. It not only showed us our strengths but also how we function as a cohesive team."
