Finally more time for real engineering work
We are driven by making engineers’ work easier with Systems Engineering!
- Simple methodology
- Structured product development
- Clear requirements and specifications
- Holistic overview of your project
- Direct and indirect dependencies at a glance
- No more trial and error
- also for non-technicians, e.g. product managers
- Short training and quick application success
Our MBSE software iQUAVIS is the key to your success!

ISO/IEC 27001 certified
Your data is important to us. Since January 2025, Two Pillars GmbH has been certified according to ISO/IEC 27001 to ensure the highest standards in information security.
How iQUAVIS came to Europe
Dr.-Ing. Christian Tschirner and Dr.-Ing. Christian Bremer founded Two Pillars GmbH in Paderborn in 2018 with the vision of making engineers’ work easier with systems engineering. The German Fraunhofer-Gesellschaft and the Japanese IT group DENTSU SOKEN INC. (formerly Information Services International-Dentsu (ISID)) recognized the potential for innovation and product development work and participated in June 2018.
Since then, Two Pillars has been acting amicably in the sense of a joint venture, and since 2023, Two Pillars has actually been a subsidiary of the DENTSU SOKEN Group and acts as an expert in systems engineering in Europe and a bridgehead for DENTSU SOKEN between the two major industrial nations of Germany and Japan.
The founding of Two Pillars in 2018 was preceded by a number of milestones that facilitated the transfer from university research to industry.

Dr.-Ing. Christian Tschirner
How can products be developed better and faster? I asked myself this question as a little boy and always used abstract sketches for “my projects”. During my studies, it became clear to me: This is systems engineering! However, I was impressed by the rigid interpretation of the approach and esp. disrupted the usability of the existing software – and at the same time it appealed to me so much that I wanted to change something. And then I discovered iQUAVIS! This allows me to integrate my ideas into an outstanding tool – for innovation in the product and more transparency in the process.
Dr.-Ing. Christian Bremer
Since my youth, two topics have fascinated me equally: technical systems and software. During my mechanical engineering studies, I supposedly chose one, but never really left the other. With Two Pillars, I can now combine both. My ambition is to keep creating new, innovative software solutions for our customers, who use them to successfully develop complex technical systems. I am driven by curiosity, drive and the joy of developing things. My family gives me the energy for this.
Since the beginning, Two Pillars has relied on the cooperation and involvement of strong experts, who have repeatedly motivated us to spin off this company from Fraunhofer IEM and to transfer its strong research performance into practice. Prof. Dr.-Ing. Roman Dumitrescu (University of Paderborn), Prof. Dr.-Ing. Albert Albers (KIT) and Prof. Dr.-Ing. Lydia Kaiser (TU Berlin) accompany Two Pillars with a scientific eye, Prof. Dr. Christoph von Einem with entrepreneurial and legal drive. Colleagues such as Dr. Lukas Bretz (Miele), Dr. Michael Hillebrand (John Deere) and Jörg Heihoff-Schwede (CLAAS) have also motivated us again and again and cooperated closely in their previous roles at Fraunhofer. That’s the spirit of Two Pillars: Building connections – just like in systems engineering!
