We work at the intersection of science, capital, and time.
German Deep Tech Group
We build institutional capacity around technologies that take time to matter — and that sovereign economies cannot afford to import.
Our real estate portfolio gives us something rare in technology: independence from the exit calendar. We use that independence to back research, build institutions, and develop partnerships that compound over decades — not quarters.
Real assets. Long horizons. No external capital cycle to answer to.
Group
GDT Group
An entrepreneurial holding at the intersection of deep research, industrial application, and permanent capital. We commit to the technologies that critical infrastructure depends on — at the stage where no fund would, and for the duration no fund could. We do not time markets. We build them.

GDT Institute
The institutional layer between what research produces and what industry and policy can deploy. We enter at the point where the translation fails — sharing risk with those who build, not billing hours to those who commission.
Institute →Independence
Foundation
A listed castle in Brandenburg. A preserved art collection. 70,000 sqm of real estate that answers to no external timeline. The material expression of what it means to build for decades rather than quarters. And, quietly, one of the more consequential places where German technology and policy meet.

“The technologies that change industries rarely announce themselves early. We pay attention to the ones that don’t.”

Schloss Fuerstlich Drehna
Some conversations happen better away from the city.

Old walls, new art, and conversations about what comes next in software. The Software Management Executive Retreat at Schloss Fuerstlich Drehna brought together senior decision-makers to address collaboration, global tech competition, and digital sovereignty.
May 2026Marc Hildebrandt on AI governance at the Executive Retreat: If AI lets you ship software three times faster, you also need to understand, review, and own what you ship three times faster. Governance matters more than productivity alone.
May 2026We kicked off this morning. At Schloss Fuerstlich Drehna, the Software Excellence Network opened the Software Management Executive Retreat 2026. Two days. A closed circle of senior corporate decision-makers. One question: In the age of AI, how do we steer software production strategically, with proper governance and executive-level accountability?
May 2026Every road, building, power line, and rail tunnel now produces more data than any team of engineers could read. Algorithms classify the images, spot the cracks before inspectors do, update the 3D models before the next audit cycle starts. The real question is who owns the system that does the reading. Spatial intelligence is not a technology question anymore. It is a sovereignty question.
We work with people who understand that the most consequential technologies take decades — and that those who wait for market confirmation arrive too late.
