DeteQt

DeteQt focuses on pioneering quantum sensing technology, providing innovative solutions through advanced diamond-on-silicon quantum magnetometry systems that enhance measurement precision across multiple industries. Founded in 2023 by CEO Jim Rabeau and CSO Omid Kavehei in Darlinghurst, Australia, DeteQt specializes in quantum sensing technology, particularly its diamond-on-silicon quantum magnetometry systems. In April 2026, DeteQt raised USD 5 million in seed funding led by Main Sequence Ventures, with participation from BOKA Group Holdings, ATP Fund, Beaten Zone Venture Partners, Uniseed, and The University of Sydney - Australia. DeteQt specializes in advanced quantum sensing technology, prominently featuring its small, stable diamond-on-silicon quantum magnetometry systems.

These systems employ NV diamond sensors that detect weak magnetic fields with high accuracy, enhancing measurement precision across various challenging environments. The core technology is encapsulated within a CMOS chip design, offering a low-cost and durable solution ideal for industries such as navigation, medical imaging, and mineral exploration. DeteQt’s products are engineered for seamless integration with existing systems, providing real-time vector magnetic field detection and utilizing industry-standard interfaces. The company primarily serves clients in regions with a high demand for innovative sensing solutions, including North America, Europe, and parts of Asia-Pacific, catering to both commercial enterprises and research institutions.

DeteQt generates revenue through direct sales and partnerships within its target industries. Transactions typically involve B2B arrangements where the company collaborates with clients in navigation, mining, and medical imaging sectors. The revenue model includes product sales of their flagship quantum magnetometry systems, which are offered under flexible pricing plans suited to the specific needs of enterprise customers. By providing tailored solutions and support, DeteQt fosters long-term relationships with its clients, ensuring repeat business and a steady revenue stream.

These transactions enable clients to leverage DeteQt’s technology for precise magnetic field sensing, thereby enhancing their operational capabilities. The company plans to use the April 2026 funding to develop its next‑generation quantum magnetic sensor, scale diamond chip manufacturing, and expand the team.
