The company will use the new funding to expand its team, scale production of cryogenic switches, and advance the development of integrated cryo-CMOS chips designed for next-generation quantum systems.
Founded in 2025 FrostByte is led by CEO James Kroll and CTO Luc Enthoven. It is scientifically supported by Fabio Sebastiano and Masoud Babaie, both recognised pioneers in cryo-CMOS technology with extensive research experience now being translated into commercial applications.
World-leading expertise in cryo-CMOS
FrostByte’s solution is to move part of the control architecture closer to the core of the computer, rather than keeping it on the outside. This makes systems easier to scale, smaller, and more power efficient, which makes the technology relevant to virtually every organisation working on quantum computers worldwide. It is enabled by cryogenic chips, which operate at extremely low temperatures.
Features include:
- The development of cryo-electronics: they design specialized cryo-CMOS (Complementary Metal-Oxide-Semiconductor) circuits that can operate inside the refrigerator at extremely low temperatures.
- The creation of cryogenic switches: they produce integrated circuits and switches that can control, bias, and read out quantum devices locally.
- Scalability: By moving the control infrastructure closer to the processor, they reduce the need for external cabling, heat generation, and system complexity, which is essential for building computers with millions of qubits.
FrostByte is exactly the kind of company that shows what the Dutch knowledge economy is capable of producing.”
“FrostByte is exactly the kind of company that shows what the Dutch knowledge economy is capable of producing,” says Auke van den Hout, Managing Partner at Graduate Ventures. “This investment fits within Graduate Ventures’ broader strategy of backing key technologies such as quantum, AI and climate tech, where fundamental research is translated directly into industrial application.”
“The perfect investor for a deeptech company”
“For a deeptech player like us, Graduate is a uniquely well-suited investor,” says James Kroll, CEO and co-founder of FrostByte. “They understand what it takes to commercialise technology rooted in decades of academic research. On top of that, the access to their network of seasoned entrepreneurs is exactly what you need at this stage, particularly for a company operating at the intersection of science and industrial scale-up.”
FrostByte is a spin-off from TU Delft and QuTech, which is internationally recognised as one of the world’s leading institutes in quantum technology. Graduate previously also invested in QuantWare, another QuTech spin-off, which has since grown into one of the world’s major suppliers of superconducting quantum chips, with customers in more than 20 countries.
