Florian Seibel

Overview
Florian Seibel is a German entrepreneur and the co-founder and co-chief executive officer of Quantum Systems, the Gilching-based uncrewed-aerial-systems company he established in 2015.
Why this entity matters
Seibel is one of the most prominent figures in Europe's emerging defence-technology sector. Under his leadership, Quantum Systems grew from a civilian drone-mapping start-up into a dual-use company valued at approximately $8 billion following its 2026 Series D round, and he is frequently quoted on Europe's need to build independent defence and technology capacity.
Career, company, or institutional background
Before founding Quantum Systems, Seibel served as an officer in the German Bundeswehr and trained as a military helicopter pilot. He later worked as an aerospace researcher at the University of the Bundeswehr Munich, where he studied flight-systems dynamics and co-developed a patented concept for a vertically launchable transition aircraft. He left his doctoral research to commercialize the technology, founding Quantum-Systems GmbH in January 2015.
Role in the startup, technology, investment, or innovation ecosystem
As co-founder, Seibel has guided the company's product strategy and its pivot from agricultural mapping toward defence and reconnaissance systems. Following a 2025 leadership reorganization, he shares the chief-executive role with co-CEO Sven Kruck, with Seibel concentrating on products, technology, and long-term strategy while Kruck focuses on operations, sales, and finance.
Selected relationships and affiliations
Seibel co-founded the company alongside fellow University of the Bundeswehr Munich researchers Dr. Michael Kriegel, Tobias Kloss, and Armin Busse. Through Quantum Systems he works with investors including HV Capital, Balderton Capital, Blackstone, Airbus, and Thiel Capital, and the company partners with drone-software firm Auterion.
