QNu Labs Raises ₹200 Crore As India Pushes Quantum-Safe Cybersecurity

QNu Labs has raised ₹200 crore in fresh Series A1 funding, Inc42 reported, giving the Bengaluru quantum-cybersecurity company new capital for product development, sales expansion and government-linked research commitments.

The round was co-led by India's state-backed National Quantum Mission and Speciale Invest.

Sony Innovation Fund, Gaja Capital, Artha Ventures and other investors also joined, taking QNu Labs' total capital raised to ₹375 crore after an earlier ₹60 crore Series A round.

The transaction lands as India's quantum-technology agenda moves from research policy toward commercial infrastructure.

Gupta and Srinivasa Rao Aluri started QNu Labs in 2016, and the company now builds systems intended to protect data and communications from threats that could emerge as quantum computing weakens older cryptographic methods.

The company plans to direct the money into R&D, go-to-market work, sales capacity and partnerships.

Gupta told Inc42 that the business will also put funds into internal processes, IT and automation as it shifts from a technology-development phase toward a “proof-of-scale” operation.

A new platform, QShield 2.0, is one of the clearest product markers in that shift.

The system focuses on discovering and assessing cryptographic assets, a step enterprises need before they can plan migration to quantum-safe security.

QNu Labs already sells products built around quantum random number generation, quantum key distribution and post-quantum cryptography.

The funding also supports a public-sector requirement attached to QNu Labs' Research, Development and Innovation Fund project.

The company received a ₹150 crore award under the government programme, with private matching capital required before the work could proceed.

The new round helps satisfy that requirement, and QNu Labs has signed the final term sheet for the project.

Beyond enterprise cryptography, the startup is working on security systems for drones and satellites.

Its drone security technology is already in pilot deployments, and Gupta expects that offering to serve defence-sector demand.

The international plan is split between products and platforms.

QNu Labs operates in Australia and the US, works through partners elsewhere, sells hardware and software in India, and is leaning more heavily overseas on subscription-based platforms for customers in sectors including banking and healthcare.

That mix matters because the company is not only selling one encryption tool.

Its portfolio spans random-number generation, key distribution and post-quantum cryptography, giving it several routes into organisations that must first map their cryptographic exposure and then decide which systems need hardware, software or subscription services.

The company employs about 180 people, with its quantum-safe VPN described as its most sought-after product.

Gupta tied the raise to a broader timing question for the market, arguing that quantum technology is moving closer to mainstream use and that India is targeting 2029 for the transition.

For now, QNu Labs leaves the round with new institutional capital, a signed RDI term sheet, pilots in drone security and a larger mandate to scale quantum-safe tools for enterprise and defence customers.
