30 YEARS OF HISTORY...

The founding of SII Deutschland GmbH as AIDA Development GmbH

The story of SII Deutschland begins in 1996. Driven by a lifelong fascination for aviation and a desire for new ideas, Frank-Heinrich Schoenenberg, together with his partner Peter Miehlke, founded AIDA Development GmbH (the original name of SII Deutschland GmbH). From the very beginning, Schoenenberg was a true pioneer, constantly seeking innovative solutions and new challenges. Over the years, he expanded the company’s services and areas of activity, thus laying the foundation for its future growth and success. This milestone marks the entrepreneurial start of a company that would go on to become an important player in the industry.

The founding of SII Technologies GmbH

In 1997, a small group of ten technology enthusiasts with a big vision founded Cadcon GbR, which would later become SII Technologies. What began as a traditional engineering office quickly developed into a center of rapid growth and innovation. We continuously expanded our services and rapidly established ourselves in mechanical engineering, energy and environment, as well as the automotive industry. This founding milestone not only marked our beginning but also laid the foundation for our ongoing commitment to technical excellence and our customers’ success.

AIDA Development (now SII Deutschland) becomes a member of the SII Group.

In 2010, SII Deutschland became part of the French engineering group SII Group. This strategic step marked a turning point in the company’s history and opened access to a global network spanning 20 countries. The international presence created new opportunities, expanded expertise, and opened doors to previously untapped industries. With strengthened capabilities and cross-border collaboration, SII Deutschland was now well‑equipped for ambitious growth. The foundation for expansion was laid—and the path toward becoming a leading player in engineering and digital services had begun.

Rücker Aerospace GmbH is acquired by AIDA / SII Deutschland

In 2014, AIDA Development GmbH acquired 100% of Rücker Aerospace GmbH and shortly thereafter merged with it to form SII Deutschland GmbH. Rücker Aerospace GmbH offered services for the aerospace industry and related sectors, as well as for the defense industry.

SII Technologies becomes a member of the SII Group

A major milestone was the integration of Cadcon into the SII Group in 2015. This step changed everything and led to our rebranding as SII Technologies. As part of this global corporation, we gained access to an international network across more than 21 countries. Through this new affiliation, we also acquired valuable additional expertise and significantly expanded our service portfolio. We were now able to offer solutions in new sectors such as banking, insurance, transportation, and aerospace, solidifying our position as a versatile and globally connected engineering partner.

One identity – Combined strengths: SII Group Germany is born

The year 2020 marked a strategic decision for SII Technologies and SII Deutschland. We unified our business operations and brand identity and now operate as SII Group Germany. The aim of this decision was to maximize our combined strength and increase our market presence. By pooling resources and fostering synergies, we created a more coherent and efficient organization. This collaboration strengthens our global position, allows us to have a greater impact within the SII Group, and enables us to provide even more comprehensive support to our customers worldwide.

Mission 2030 – The shared path

In 2025, SII Group Germany is taking a decisive step forward: it is integrating its administrative departments and enabling cross‑team collaboration on shared customer projects. The launch of our unified website underscores this transformation and demonstrates our strength, transparency, and commitment to excellence. This milestone represents the beginning of a shared mission: growing together, driving innovation together, and achieving ambitious growth and revenue targets by 2030. By combining our strengths, we present ourselves as a united front to employees, customers, and suppliers—ready to shape the future with purpose and determination.
