Florian Seibel flew helicopters for the Bundeswehr and did doctoral research at the University of the Bundeswehr Munich. He and a colleague patented a drone prototype, and he left the PhD to found Quantum Systems in January 2015.
The first Trinity prototype flew in 2016, the Tron eVTOL system followed in 2017 and Trinity production began in 2018. Customers were civilian, mostly agriculture and surveying. In a 2018 interview Seibel's advice was that what can go wrong will go wrong.
In September 2020 Quantum Systems partnered with Auterion on the Vector drone. After Russia's 2022 invasion of Ukraine the company moved toward defense. The first Vector went to the Dutch Ministry of Defence in October 2022, and Australia chose Vector for Land 129 in July 2024.
Funding followed: €63.6 million in October 2023 and €160 million in May 2025, which made it Europe's first dual-use unicorn. Germany approved a framework agreement for 747 drones in December 2025, and a $1.2 billion round in July 2026 valued the company at $8 billion.
