QuantumDiamonds, a Munich-based semiconductor testing company, has closed a €15 million equity funding round led by World Fund, with participation from Bayern Kapital, IQ Capital, Earlybird, First Momentum, UnternehmerTUM, Creator Fund, Onsight Ventures, and angel investors.
The funding marks a significant milestone for the deeptech startup, which was spun out of the Technical University of Munich in 2022. Combined with €76 million in EU-backed non-dilutive state funding already secured, QuantumDiamonds has now mobilized a total of €91 million to accelerate its growth and establish itself as a key player in quantum sensing technology for semiconductor manufacturing.
Scaling Production and Infrastructure
The capital will be directed toward scaling production of the company’s quantum sensing technology and expanding operations, with a particular focus on establishing a high-tech semiconductor testing facility in Munich. This investment arrives at a critical juncture as semiconductor manufacturers worldwide seek solutions to yield challenges that existing testing systems struggle to address.
Kevin Berghoff, CEO and co-founder of QuantumDiamonds, commented on the significance of the round: “This is a major step in bringing quantum sensing into fabs worldwide. The response from leading chipmakers has been clear: they see our technology as essential for solving yield challenges that today’s systems can’t address.”
The company’s technology leverages quantum physics principles to detect defects and anomalies in semiconductor production with unprecedented precision. By identifying issues earlier in the manufacturing process, QuantumDiamonds’ solutions aim to reduce waste and improve overall chip quality—critical concerns as the semiconductor industry faces mounting pressure to maintain yield rates amid increasingly complex manufacturing processes.
European Semiconductor Autonomy
The investment also reflects broader European strategic objectives. As the EU continues efforts to reduce technological dependence on the United States and secure its supply chains, support for homegrown semiconductor innovation has intensified. The combination of equity funding and substantial state backing signals confidence in QuantumDiamonds’ potential to contribute to European semiconductor self-sufficiency.
The participation of established venture capital firms and corporate investors alongside public funding demonstrates the viability of the company’s business model. Bayern Kapital, IQ Capital, and Earlybird bring deep expertise in scaling deeptech ventures, while UnternehmerTUM’s involvement reflects the academic roots and entrepreneurial ecosystem surrounding the Technical University of Munich.
QuantumDiamonds joins a growing cohort of European deeptech companies attracting significant capital as investors recognize the long-term competitive advantages of quantum and advanced sensing technologies. With production scaling and facility development now underway, the startup is positioned to establish itself as a critical infrastructure provider for semiconductor manufacturers seeking to maintain competitive advantage in an increasingly quality-focused market.
