What Hiqute Diamond does

HiQuTe Diamond is a French deeptech company incorporated in December 2022 that manufactures ultra-high-quality synthetic diamond plates and wafers using Chemical Vapor Deposition (CVD). The company was spun out of the LSPM-CNRS laboratory, leveraging 30 years of academic diamond research and a founding team of five LSPM researchers led by CTO Riadh Issaoui and CEO Florent Alzetto. It operates an R&D facility at the LSPM-CNRS site in Villetaneuse and its corporate headquarters in Boulogne-Billancourt, with a team of 1-10 employees combining more than 100 years of cumulative diamond expertise.

The company sells three configurable product families—Bleu (boron-doped bulk diamond for power electronics), Blanc (ultra-pure 12C-enriched bulk diamond), and Rouge (NV-doped diamond for quantum applications)—along with layered structures such as 12C-enriched layers on ultra-pure substrates and NV-doped layers on ultra-pure substrates. Its technology stack rests on custom in-house CVD reactors, patented large-diameter growth (up to 5x5 mm² for boron-doped plates), patented dislocation reduction, advanced doping control (boron, nitrogen, isotopic enrichment), precision laser cutting and polishing, and characterization via AFM, Raman spectroscopy, and photoluminescence imaging.

HiQuTe Diamond targets enterprise customers in three vertical use cases: power electronics (data centers, electric mobility, communications), quantum computing (edge devices, NV-center-based qubits), and quantum sensing (medical diagnostics, industrial quality control). Go-to-market is direct enterprise sales with custom quote-based pricing and no public price list, reflecting the bespoke nature of the products. Revenue is generated through hardware sales of diamond plates and wafers. As of mid-2025, the company had raised €7.5 million (approximately $8.78M) from Bpifrance, the Île-de-France Reindustrialization Fund, IXcore, Socadif, and TF Participations, with proceeds dedicated to launching an industrial pilot line in Île-de-France and scaling production capacity.

Core offering

HiQuTe Diamond manufactures ultra-high-quality synthetic diamond plates and wafers using Chemical Vapor Deposition (CVD) for advanced technology applications. The company sells three product ranges — Bleu (boron-doped for power electronics), Blanc (ultra-pure for quantum applications), and Rouge (NV-doped for quantum sensing and computing) — configured with custom dimensions, thickness, isotope selection (natural carbon or 12C enriched), and optional electron irradiation. Products are sold directly to enterprise technology developers through a custom quote-based ordering process.

Product overview

HiQuTe Diamond offers a portfolio of ultra-high-quality synthetic diamond products for advanced technological applications. The core product line consists of three diamond grades: Bleu (boron-doped bulk) for electronics with conductive properties, and Blanc (ultra-pure bulk) and Rouge (NV-doped bulk) for quantum applications. These products are offered as bulk substrates or with specialized layering configurations including 12C isotope enrichment and NV-center doping. The company provides tailor-made dimensions, thickness options, and isotopic specifications to meet specific application requirements in quantum computing, quantum sensing, and power electronics.

Broad incumbent offering diamond substrates, NV-center solutions, and thermal-management products that overlap directly with HiQuTe's Bleu, Blanc, and Rouge ranges, but at much greater scale and broader portfolio.
• Wolfspeed: US-based incumbent in wide-bandgap SiC power-electronics substrates and devices. Competes indirectly with HiQuTe's Bleu diamond plates as an alternative substrate for high-voltage, high-frequency power-conversion applications.
• Soitec: French leader in engineered semiconductor substrates (SOI, SiC, GaN, InGaAs). Comparable as a substrate manufacturer addressing power-electronics and RF applications; HiQuTe's diamond substrates sit on the same European technology-sovereignty roadmap.

Emerging players

• Qnami: Swiss deeptech commercializing NV-center diamond quantum sensors for nanoscale magnetic imaging. Overlaps with HiQuTe's Rouge line as a customer-like integrator of NV-grade diamond material into quantum sensing products.
• RFHIC: GaN/compound-semiconductor foundry specializing in RF and power-electronics devices. Comparable as an emerging compound semiconductor/substrate-adjacent player addressing similar EV, 5G, and power-conversion customers as HiQuTe.

Others

• IMEC: Belgium-based global semiconductor R&D center that runs research programs on wide-bandgap materials including diamond for power and quantum. Not a competitor but a critical ecosystem player likely to qualify, integrate, or co-develop with HiQuTe for downstream applications.
