Qubitrium has raised €2.25 million in seed-plus funding to build its space-based quantum communications business. (qubitrium.tech) The round closed in December 2025, according to the company, with Türkiye Development Fund contributing €1.25 million and ACT Venture Partners adding €1 million. (qubitrium.tech) Qubitrium said it will use the money to expand its technical team and infrastructure, push product development toward deployment, and support early customer implementations. Webrazzi reported the company also plans to accelerate partnerships and go-to-market work. (qubitrium.tech) (webrazzi.com) Quantum key distribution works by using single particles of light to create encryption keys, so any eavesdropping changes the signal and can be detected. Qubitrium has built its business around shrinking that hardware into payloads small enough for nanosatellites and CubeSats. (actvp.vc) (sahaistanbul.org.tr) That space angle is central to the pitch: satellites can connect long distances that fiber-based quantum links struggle to cover without repeaters or trusted relay points. Tech.eu said Qubitrium’s 2024 seed round was tied to a plan to launch a 2U satellite carrying a quantum key distribution payload. (tech.eu) The company was founded in 2020 by Dr. Kadir Durak, a faculty member in the Electrical and Electronics Engineering Program at Özyeğin University. The university said ACT Venture Partners led Qubitrium’s earlier €1.5 million seed round in September 2024. (ozyegin.edu.tr) (tech.eu) ACT Venture Partners said in 2024 that Qubitrium had also received support from NATO’s Defence Innovation Accelerator for the North Atlantic, or DIANA, where it tested miniaturized quantum key distribution systems for nanosatellites. (actvp.vc) Webrazzi reported on April 22, 2026 that Qubitrium had recently placed its QubitCore payload into low Earth orbit on SpaceX’s Falcon 9 Transporter-16 mission and then generated its first quantum keys in space. The outlet said the company reported operation between 0 and 35 degrees Celsius and output of more than 500 256-bit keys per second. (webrazzi.com) The financing lands as venture investors in Türkiye remain active but selective: KPMG counted 360 startup deals worth $1.4 billion in 2025, up from 331 deals in 2024, while total value fell from $2.6 billion as mega-deals disappeared. (assets.kpmg.com) For Qubitrium, the new round extends a path from university lab work to hardware in orbit and, if the company can turn those payload tests into contracts, to commercial quantum communications products.
