What Kwan-tek does
Kwan-tek is a French deep-technology company headquartered in Ploemeur, Brittany, that designs, manufactures, and commercializes metrology solutions based on Nitrogen-Vacancy (NV) center diamond quantum sensors. The technology relies on optical interrogation of synthetic diamond NV defects to measure magnetic fields and temperature with high spatial resolution (sub-100 micrometer) and stability at room temperature, without requiring vacuum or cryogenics. Its product portfolio spans five lines: KWANTEACH, a turnkey modular education platform (Base and Pulsed modules) used in quantum-physics curricula at roughly 20 universities worldwide; Non-Destructive Testing (NDT) systems that detect microcracks, grinding burns, and martensite in metallic components for aerospace, defense, energy, and nuclear customers; Quantum Magnetometers and High-Field Magnetometers for precision instrumentation; Quantum Navigation sensors providing drift-free magnetic heading data; and Quality Control instrumentation for NV-grade diamond certification.
The company generates revenue through hardware sales of these quantum sensing instruments, an exclusive licensing/commercialization arrangement with Metrolab for NV Diamond magnetometers in the precision-instrumentation market, recurring annual maintenance and support subscriptions, and custom R&D services for characterization of quantum diamond materials. It pursues a sales-led go-to-market model combining direct enterprise engagement in aerospace, defense, energy, and nuclear verticals with an international distributor network spanning Taiwan, Southeast Asia, Australia/New Zealand, Japan, and China, plus partnerships with CETIM, ELyTMaX Laboratory, HIQUTE DIAMOND, and Institut FOTON. Kwan-tek was legally formed in October 2023 through the buyout of WAINVAM-E assets by CEO Remi Geiger alongside Breton investment companies Breizh Rebond and S.F.L.D., inheriting approximately €8M of prior R&D and IP and 20 years of underlying research; it employs 24-25 people and is backed by approximately €5M of equity (including a €1.2M seed round in September 2024) and a €1.9M i-Démo grant under France 2030.
