Delft Circuits focuses on Cri/oFlex®, a flexible, cryogenic high-density I/O system engineered to remove the performance and thermal bottlenecks that traditional cabling introduces in large-scale qubit machines. The technology is sold to quantum hardware builders and is now being integrated into dilution refrigerators through a partnership with Bluefors. The firm recently hired long-time Boston Consulting Group veteran Martin Danoesastro as CEO to steer its next growth phase. Fresh capital will fund continued product innovation, additional technical hires, and expanded manufacturing capacity. Management also intends to leverage new investor Paeonia Group’s network to enter North American and Asian markets. A next-generation Cri/oFlex® product roadmap has already been published, underscoring plans to stay ahead of emerging quantum-computing I/O requirements. Including the latest extension, Delft Circuits has raised €15 million ($17.5 million) to date.
