Quantum-safe cybersecurity startup QNu Labs plans to accelerate revenue growth as it shifts from technology development to large-scale deployment across defence, government, banking, telecom and critical infrastructure.The company will use its recently raised ₹200-crore Series A1 funding to accelerate R&D, field trials, product integrations, certifications, sales expansion and partnerships, co-founder Sunil Gupta said. The round was led by the National Quantum Mission and Speciale Invest, with participation from Sony Innovation Fund, Gaja Capital and Artha Ventures, taking QNu Labs’ total capital raised to ₹375 crore.The Bengaluru-based company is now looking to move beyond technology demonstrations and make implementation a key differentiator as enterprises prepare for the transition to quantum-safe infrastructure. Gupta expects demand to build sharply from 2027-28, as organisations move from cryptographic discovery and readiness assessments to actual deployment.QNu Labs is already seeing traction in defence and government, while discussions are expanding across data centres, critical infrastructure, banking and telecom. The company is currently in discussions with banks.Its discovery platform maps cryptographic assets across applications, middleware, hardware and communications, giving enterprises a readiness score and a prioritised implementation roadmap. This is expected to become an entry point for customers before they undertake multi-year migration programmes.The acceleration in demand is also reflected in the company’s pipeline. QNu Labs has seen eight RFPs in the last two months, compared with seven over the preceding four years. Defence deals are currently in the ₹4-5 crore range, while initial enterprise engagements are around ₹40-50 lakh, with deal values expected to rise as deployments scale. The company is also projecting to achieve an order book of around ₹120 crore this year.QNu Labs is also expanding beyond quantum security into AI security, with plans to assess vulnerabilities across large language models, training data, agentic layers, APIs and open-source components. Gupta sees AI security potentially becoming comparable in opportunity to quantum security, with adoption likely to be driven by regulation and increasing enterprise AI usage.Internationally, QNu Labs has two US customers through its US entity enQase, with which it is also pursuing partnerships across West Asia, Africa, Australia and Europe.The company plans to expand its existing portfolio of 15 patents, with around 50 additional patents planned. It is also working on quantum sensing and quantum-secure communications, including a planned satellite deployment, as it builds towards its ambition of becoming a global trust layer for quantum and AI security.Published on September 9, 2026
