"Tilia is not a typical consulting firm. The result of this really pleasant and professional cooperation: significantly improved cooperation in the entire company on IT issues, as well as proven optimization in IT organization and operation. I highly recommend Tilia for IT performance optimization and digitalization!"

Dr. Emanuel GrünBoard of Water Management Associations Emschergenossenschaftund Lippeverband | eglv

"Rising energy costs, higher levies and new requirements demanded a concept that provides economic supply, prevents extreme price fluctuations and is environmentally friendly. Energy supply is not our core business, which is why our partner Tilia has developed a tailor-made energy concept that convinced us. As part of a cooperation investment, Tilia Solutions GmbH implemented the new heating center, which consists of two highly efficient combined heat and power plants, as well as a ventilation and absorption refrigeration plant. The entire plant produces the complete heat and cold and about 50 percent of the required amount of electricity. We are very satisfied with the result."

Hendrik P. DeschCEO, DESCH Antriebstechnik GmbH & Co. KG

"Together with the University of Aalen and Tilia GmbH, the municipality of Essingen set out on the path to becoming a CO2-neutral municipality in 2018. After a thorough inventory and analysis of the current situation, various options for a future climate-neutral heat supply were identified. In the meantime, at the end of 2020, we were able to pass a resolution in the municipal council to set up a local heating network in the centre of Essingen, which will be built already this year. I would like to expressly thank Aalen University and Tilia GmbH for their excellent support. Our eyes have been opened and we have also been given practicable suggestions for the way forward."

Wolfgang HoferMayor, Municipality of Esslingen

“As a growing IoT company, it is a joy for us each day to be able to count reliably on the professional support of Tilia as an experienced partner – pleasant, always with a cool head when it comes to finances and with a clear vision for pragmatic solutions.”

Felix AdamczykCEO, qiio AG
