Mr. Rehberger has been a financial companion for me for many years. Easily accessible, reliable, calm and very pleasant to deal with. He is excellent at explaining things and does not exert any unpleasant sales pressure. His training and professional expertise are excellent. An unreserved recommendation from me.

It would have been nice if our tax advisor had made us aware of the possibilities of the IAB. After Michael had shown us the possibilities and advantages of IAB projects in detail, we quickly realized that we would make use of them. Michael handled the entire process very professionally. Only the product provider itself sometimes took a little longer for feedback and the current project status. We look forward to continuing our collaboration with Michael Rehberger.

Michael has explained to me how the SIT-Token works and showed me all I need to know to start my first investment. The 18% rewards are paid out second by second and I can see them grow when I refresh my browser after some minutes. The price of the SIT-Token has also been rising by 20% from September. Thanks for the explanations and the help!

Michale Rehberger was recommended to me for the topic of PV systems. After a clear and very detailed consultation and answers to all my questions, I decided to go ahead with the project. The contract for a PV project was signed in 1-2024 and the PV system has been producing electricity since 12-2024. The cooperation with H. Rehberger was extremely good, and everything went smoothly and with very little effort on my part.

Michael patiently explained everything I needed to know about Bitcoin in a way that was easy for a layperson to understand. The videos provided allow everyone to listen to them as often as necessary to deepen or refresh their understanding. Superbly prepared.

In response to my inquiry, Michael Rehberger arranged a PV system for an IAB that had already been formed. The communication with Mr. Rehberger was very prompt. The economic data of the PV plant positively surprised my tax advisor. The financing through a specialist was not easy, but was finally solved. Now I am looking forward to the planned commissioning of the PV plant in the summer of 2023.

Thank you very much for the great support and with it also an absolute recommendation for all who work with Mr. Rehberger.

With Mr. Rehberger we have found a competent partner for the acquisition of PV plants. With the first plant there were unfortunately longer delays, because of an incorrect entry in the land register. Since then, the power production of the PV plant runs smoothly.
