DELFT, Netherlands, Apr 8, 2026 – Delft Circuits has appointed Karen Keenan as chief operating officer (COO) as it builds out its global quantum I/O hardware manufacturing capacity. She replaces Maarten Hendriks, who will take on responsibility for developing the company’s Quantum Fab infrastructure in Netherlands.
The leadership change comes as Delft Circuits progresses work on a dedicated Quantum Fab facility for manufacturing cryogenic quantum I/O hardware. The company is also extending its global commercial and field operations to support customers as demand rises.
“We are entering a new phase of our growth, where scaling operations becomes just as important as advancing the technology itself. I am excited to join at this key moment and to work with the team building the operational backbone required for our global growth, while preserving the quality and innovation that define the company,” said Karen Keenan, COO at Delft Circuits.
“We have built a strong operational foundation over the past years, and the next step will help us scale it even further. Karen brings exactly the right leadership and experience needed for this phase. I am excited to now focus fully on expanding our Quantum Fab and infrastructure in the Netherlands, ensuring we are ready to support the growing demand for quantum I/O hardware on a global level,” added Maarten Hendriks.
Recent additions to the leadership team include the appointments of Martin Danoesastro as CEO and Robby Ferdinandus as CCO, indicating a shift toward industrial-scale operations.
CEO Martin Danoesastro added: “Our customers are rapidly scaling their quantum systems, driving a new level of demand for reliable, industrial-grade I/O hardware. The next step is to industrialize that scale globally. Karen brings the experience required to scale our operations to meet increasing global demand and drive execution at speed, while Maarten focuses on expanding our Quantum Fab and infrastructure. In parallel, we are strengthening our global customer-facing capabilities to serve them at scale. Together, this leadership team positions Delft Circuits to accelerate growth, attract top talent, and partner with the leading players shaping the future of quantum systems.”
Keenan holds bachelor’s and master’s degrees in aerospace engineering from TU Delft and began her career at Boston Consulting Group (BCG). At Luuna (now Zebrands), she helped scale the company from 35 to more than 800 employees and grew revenue from $5 million to over $100 million, while improving operating performance.
