Vertranium Academy

Marcel is a top trainer who puts a lot of emphasis on conveying understanding and always tries with a lot of verve to help everyone who wants to participate and become successful. There hasn't been a session where I haven't learned something new or been able to refine my existing knowledge.

I really like the way the whole training is structured. You get a much deeper insight into the topic of sales and a stronger mindset. This makes it much easier for me to go into conversations with my contacts. Thanks for everything so far!

I think it's great that you can choose the topics that concern you the most and discuss them in the group. That way, individual challenges are solved much better. There is a consistently pleasant atmosphere and you always feel welcome. By using various methods to simulate different situations with potential customers in everyday life, you learn a lot for your own everyday sales life. I'm already looking forward to the other trainings.

The trainers really do a great job! You feel very comfortable and get first-class input regarding sales and personal development. Everyone is welcome and can ask open questions. I have been able to take away a lot so far, which has had a positive effect on my everyday sales life. I am looking forward to many more trainings!

The guides and support were a personal highlight. This made learning new partners much easier and comprehensible. Multipliable work at a high level!

Saturday training is a must! Anyone who does not accept and implement all the content and expertise of the trainers really has only himself to blame. Everything is presented in a very understandable and practical way. Absolutely recommendable.

I always find the exchange with experienced trainers very helpful and interesting. I particularly liked the systematics that were taught, as this has already helped me very well in some situations with potential contacts. I continue to look forward to productive meetings and good cooperation.

From day one, I felt absolutely comfortable and welcome. Both my direct contacts and the executives took attentive care of me. I didn't encounter anyone who turned me down. In addition to the technical issues, a lot of emphasis was also placed on my personal development. Even if I sometimes didn't perform at my best or felt insecure, no one gave up. On the contrary. They not only encouraged me to leave my comfort zone, but also actively supported me and said: "Come on, we're going this way together!" Now we're going this way and we're getting closer to our goals day by day.

The training on Saturday helps immensely in the daily mission to do justice to one's tasks. The exchange with the other participants from all over Germany offers a huge added value, because you get impressions and methods of different people. It's a lot of fun and I'm happy to be there every time, even though as a mother you don't often have the time. I would recommend it to anyone who wants to develop personally and in sales.

I have been lucky enough since the beginning (at the beginning also as a sideline) to be able to participate in the Saturday trainings, which has brought me extremely far in a very short time. The training offers a good mix of sales (and partly technical) training and impulses for personal development.


I also found it particularly great that constructive criticism was positively accepted and also implemented within a very short time.

Everything super explained. When questions, they were always answered directly.
Never negative to other people on the contrary always positive attitude. Stands with full conviction behind what he does. Top!

The meeting was always very informative and interesting, I always learned something new. My fears were also taken away and I always felt very comfortable. Now it is no longer so difficult for me to talk to people. Thank you Marcel!

The Saturday training supports me very much. The stories from experienced employees, as well as the conversations between the new ones, contribute a lot to the learning process. At each appointment you learn a bit more, thank you.

It was my first time and I was able to take away a lot of practical things for my work. No matter who you are and where you stand, from advanced to newcomer, this training is highly recommended.

Great exchange, lots of practical approaches with a very great group.

Anyone who doesn't take advantage of Saturday training is missing out on top-notch coaching!
I started as a sideline and enjoyed every Saturday Training with Marcel Mankas. The Saturday Training has contributed significantly to my development through the personality development and the active training of the sales and technical impulses and topics. Many thanks for that!

Through the Saturday training at Vertranium, I have benefited tremendously and am now much more confident when approaching potential clients. I now understand how best to approach my customers and can adapt much better to their individual needs. As a result, I now have many quality appointments and my clients no longer show up to the appointment with preconceptions. I can recommend the training at Vertranium to anyone who wants to improve their sales skills and take care of their customers comprehensively. Thank you Vertranium!

The Saturday training helps me to motivate myself anew every week in order to dedicate myself again to what moves me forward. The content taught has enabled me to develop personally much better and thus optimize my sales skills. In addition, I am shown again and again that things that seemed impossible to me are very much possible. I would recommend this training to anyone who expects more from life!

The training with Marcel Mankas is especially helpful to understand the purpose of why Vertranium is built the way it is. It is also very helpful to get out of your comfort zone and to grow personally. Furthermore, all questions and ambiguities can be clarified. It is professionally and intelligently structured and offers invaluable added value, both for personal development and for one's own career.

I received a complete understanding of our profession in the Saturday training. Marcel and Maik can answer ANY QUESTION and help you. The training offers a huge added value for trainees, which cannot be overestimated. Absolutely recommended for anyone who wants to experience their personal click moment.
