2025 was another milestone year for the UnternehmerTUM ecosystem, as startups from our network collectively raised more than one billion euros, demonstrating the breadth and strength of Munich’s deep-tech innovation landscape.
International investors turned their attention to Munich – and five teams stood out with exceptional funding rounds.
1. Scalable Capital – €155 million
Scalable Capital, co-founded by TUM alumnus Florian Prucker, secured €155 million and strengthened its position as one of Europe’s leading digital investment platforms. Led by Sofina and Noteus Partners, the round supports product expansion, infrastructure growth, and Scalable’s mission to make modern wealth management accessible to millions.
2. QuantumDiamonds – over €150 million
QuantumDiamonds, shaped by programs such as XPLORE, XPRENEURS, and the TUM Venture Labs, announced an investment exceeding €150 million for the world’s first production facility for quantum-based chip inspection systems. Supported by the European Chips Act, the new facility marks a key step in industrializing their quantum- and AI-powered technology.
3. Isar Aerospace – €150 million
Following the first test launch of a Western orbital rocket from Andøya, the TUM spin-off Isar Aerospace reached another significant milestone in 2025: a €150 million convertible bond from Eldridge Industries, elevating the company to unicorn status. The funding accelerates production of the Spectrum launch vehicle and strengthens Europe’s ambitions for independent access to space. Isar Aerospace is also one of UVC Partners’ earliest portfolio companies.
4. Proxima Fusion – €130 million
Proxima Fusion, supported by UVC Partners, XPRENEURS, and the TUM Venture Labs, closed one of Europe’s largest Series A rounds in the fusion sector: €130 million, led by Cherry Ventures and Balderton Capital. The funds accelerate the development of next-generation stellarator fusion technology, including the construction of crucial superconducting magnets by 2027.
5. Marvel Fusion – €50 million (Series B extension)
Marvel Fusion, founded by TUM alumni, advances a laser-driven approach to inertial fusion. In 2025, the company raised an additional €50 million – including from EQT Ventures, Siemens Energy Ventures, and the EIC Fund – bringing the total Series B to €113 million. The funding supports the transition toward industrial application of their technology.
A strong signal for deep tech from Munich
These five teams represent the power of our ecosystem: From prototypes in the MakerSpace to scale-up support through programs like XPRENEURS, Funding for Innovators, the TUM Venture Labs, and investments by UVC Partners, UnternehmerTUM empowers founders throughout their journey to global impact.
We look ahead to 2026 with excitement for the next wave of deep-tech innovation emerging from our community.
