"Mellius is leading in a good natural way, he was able to remove resistance well in our change process. He is empathetic, responding with empathy to resistance, emotions and questions. He is analytically strong: he can quickly take in specific information. And process that into a process or document that is shareable with others."

"It's always a question of what working with externals will bring. I have worked a lot with externals. I wondered beforehand what I was going to gain from working with Mellius. Mellius has exceeded my expectations. He is good at gathering, monitoring and qualifying requirements. Throw in a quarter and Mellius makes sure you get a euro back. He has a tremendous drive to add customer value. He is good at monitoring the project scope and he keeps a keen eyeon the goal of the project . I appreciate his attitude as a human being. He positions himself independently."

"I have experienced the failure of IT vendors to deliver on promises several times during system implementations. In addition, they often only looked at the cost, but not at what it would bring to the business. During the digital change process for a new risk insurance tool, we approached it carefully with an extensive Proof of Concept and by involving users extensively. Mellius was responsible for the business analysis during the PoC, change project and implementation. I would definitely recommend working with Mellius! He has a helicopter view, is good at setting priorities and connects the business and IT. The system successfully went live and has resulted in more user convenience, a 50% reduction in turnaround time for the bulk of the cases and less frustration in the department. As far as I am concerned, the methodology of this change project is the blueprint for all future digital change projects we will implement within our company."

"Under extreme time pressure - during the summer vacation - Mellius led a dedicated team to assess the functional and technical applicability of an alternative compute core. The result was that from a technical and functional standpoint, an alternative computational core was selected, allowing us to proceed with the signing of the overall deal."
Arie Edens, Head of Capgemini Retirement Services

"Mellius has a very pleasant positive personality and is therefore a nice person to work with. In addition, he can share and explain his knowledge without coming across as a pedantic or rooster. That is rare, he has a huge favor factor with clients! I also liked that he slowed me down at the beginning of the project to dwell on the 'softer' things like getting to know each other and agreeing on how we want to work together. Thanks again for that!"

"Mellius knows how to bring the right parties to the table and see/name the different interests. He combines this with a clear way of communicating, ensuring effective meetings and avoiding ambiguities. He is able to create overview and structure. As a result, he succeeds in achieving objectives and ensuring that everyone is 'on the same page'. I found it pleasant working together in our fraud prevention project."

"Mellius has been my coach for more than 3 years, our coach-coachee relationship has grown a lot. In the first year, Mellius mainly helped me find solutions to very specific problems and challenges. Then we entered a phase where he became a sparring partner who really challenges me to get the best out of myself. He provides excellent feedback and advice. All in all a very customized, educational and enjoyable experience."

"I like Mellius' enthusiastic approach, proactive behavior and energy. He is content-driven and delivers high quality. He had a great impact with leading the Proof of Concept on the pension deal with a total contract value of over €100 million. During the pension deal, he understood the overall complexity and dependencies. He did this very well! Furthermore, he understands functional as well as technical issues and can work well in a flexible agile environment."
Jimut Basa, Head of Sales Belgium and the Netherlands, Vice President, Capgemini

"I was afraid of overlooking important issues and pushing through desires that don't add value for the bigger picture. I needed someone to hold up a mirror to me. Mellius was this mirror for me; he helped me make conscious choices. He is knowledgeable, keeps the helicopter view and asks good questions about why we would want something. He thinks through and thinks one step further. Furthermore, he is approachable and allows others to have their value. Because of his help, we worked on the right things during the change process for the benefit of the consultant and the client."
