QNu Labs raises Rs 200 crore to accelerate quantum-safe cybersecurity innovation and global expansion

QNu Labs, a deeptech cybersecurity startup building quantum-safe solutions, has raised Rs 200 crore in a Series A1 funding round led by the National Quantum Mission and Speciale Invest with participation from Sony Innovation Fund, Gaja Capital and Artha Ventures, among other investors.

The latest round takes its all-time raise to to Rs 375 crore.

QNu Labs was founded by Srinivasa Rao Aluri and Sunil Gupta. It was incubated in 2016 at IIT Madras.

The startup will use the raised capital to accelerate R&D, deepen its technology leadership, and scale its sales and go-to-market capabilities across India and global markets. A part of this funding will be used as QNu's contribution towards the approved project funded under RDI to build the Technology backbone of India’s Quantum Secure and Sensing Networks (IQSN), it said.

QNu Labs said the latest investment will enable it to further extend its quantum-safe technology stack by expanding into quantum sensing and AI, stretching deployments across critical sectors, and building the capabilities required to address the rapidly emerging global demand for quantum-safe migration.

“India has moved early on in the quantum era. The National Quantum Mission, through its IIT Madras hub, has laid the foundation and with implementation timelines published in 2026 across sectors, quantum-safe technology is shifting from policy to commercial deployment. QNu Labs has spent over a decade building this stack and has already deployed across government, critical infrastructure and BFSI. Investment in indigenous capability now gives India a clear opportunity: secure its expanding digital infrastructure with sovereign technology that meets global standards and competes in global markets,” said Sunil Gupta.

“With approximately 80% of this round came from new investors globally is a strong signal that global conviction in quantum-safe security is building, and QNu is at the centre of it,” he added.

Gopal Jain, Co-founder and Managing Partner, Gaja Capital, said, "Quantum-safe security is becoming national infrastructure — as essential to a digital economy as power and transport are to a physical one. QNu Labs has spent a decade building a full stack in India, and is already deployed in the environments where trust matters most: critical infrastructure, government and BFSI. What attracted us is that the science is done and the demand curve is turning — this is now a scaling problem, and that is where we work best."
