QNu Labs Raises Rs 200 Cr In Series A1 To Scale Quantum-Safe Cybersecurity

QNu Labs, a Bengaluru based deep tech cybersecurity company, has raised Rs 200 crore in a Series A1 funding round aimed at scaling its quantum‑safe security technology as India moves from research to commercial deployment in the space.

The round was co‑led by the National Quantum Mission and Speciale Invest, with participation from Sony Innovation Fund, Gaja Capital and Artha Ventures, among other investors. The raise takes QNu Labs' total capital secured since its founding to Rs 375 crore. Roughly 80 percent of the new round came from investors backing the company for the first time, a signal of widening interest beyond its earlier domestic investor base.

QNu Labs was incubated at IIT Madras in 2016 and co‑founded by Srinivasa Rao Aluri, now chairman, and Sunil Gupta, who serves as chief executive. The company previously raised Rs 60 crore, close to 7 million dollars, in a Series A round led by the National Quantum Mission in 2025, and before that raised 6.5 million dollars in a pre‑Series A1 round led by investor Ashish Kacholia of Lucky Investments in December 2023. The jump from that earlier round to a Rs 200 crore Series A1 represents the largest single raise in the company's history, larger by itself than everything it had raised across the previous nine years combined.

The company builds what it describes as a full domestic stack of quantum‑safe technology, spanning quantum key distribution, quantum random number generation, post quantum cryptography and cryptographic key management. Its products are already deployed across government, critical infrastructure and banking, financial services and insurance clients, categories where the cost of a future encryption failure is high enough that organisations are beginning to plan migrations well ahead of when quantum computers are expected to be capable of breaking current cryptographic standards. QNu Labs says its team now includes around 160 engineers, physicists and mathematicians, and that its patented, certified and military‑grade products are already used by clients internationally to secure critical infrastructure.

A portion of the new funding will go toward QNu Labs' contribution to an approved Research, Development and Innovation project focused on building the technology backbone for India's Quantum Secure and Sensing Networks. The company was earlier awarded a Rs 150 crore project under the government's RDI Fund, which came with a requirement that QNu Labs raise a matching amount of private capital, a condition this round helps satisfy. Beyond that project, the company plans to extend its technology stack into quantum sensing and artificial intelligence, increase deployments across critical sectors, and build out capabilities aimed at meeting global demand for quantum‑safe migration as governments and enterprises elsewhere begin similar transitions.

The company has also been broadening its product line beyond its original cybersecurity portfolio. QNu Labs has built a newer platform called QShield 2.0, focused on discovering and assessing an organisation's existing cryptographic assets as it prepares for a quantum‑safe migration, essentially mapping where vulnerable encryption already sits inside a company's systems before replacing it. The company is separately developing security solutions aimed at drones and satellites, with its drone security technology already in pilot deployments and an eye toward serving the defence sector as that work matures.

The raise arrives as quantum‑safe security shifts from a policy conversation to a commercial one in India. A Department of Science and Technology report published in May 2026 set a target for quantum resilience across the country's critical information infrastructure by 2029, with broader enterprise adoption of post quantum cryptography expected by 2033, and the National Quantum Mission's IIT Madras hub has been laying groundwork for that transition through funding and implementation timelines published across sectors this year. Filed financial accounts show QNu Labs' revenue grew 64 percent to Rs 40.5 crore in the year to March 2025, with a net loss of Rs 6.2 crore, a relatively narrow gap between revenue and loss for a deep tech company still building out its product stack. If the government's 2029 timeline holds and enterprise migration follows on schedule, QNu Labs' decade spent building a domestic full stack for a transition its own government has now mandated could position the company well ahead of competitors still assembling the pieces, though execution against that timeline, and against well funded international rivals entering the same market, remains the open question the company now has fresh capital to try to answer.
