QNu Labs pockets $24M in Series A1 to push quantum-safe encryption

Quantum cybersecurity startup QNu Labs has raised $24 million in a Series A1 funding round, the company announced. The Bengaluru-based firm develops quantum-safe encryption products designed to protect data against threats from quantum computers, which are expected to break current RSA and ECC-based encryption standards.

QNu Labs offers a portfolio of hardware and software products including Armos (Quantum Key Distribution), Tropos (Quantum Random Number Generator), Q-ORE Encryptor for drone communications, and platform solutions such as QShield, QVerse for messaging, QConnect for VPN, and KyntraQ for key management. The company's Armos and Tropos products are currently available through the Indian government's Government e-Marketplace (GeM) procurement portal, indicating early traction in public sector adoption.

The funding comes as the company positions itself within a growing global quantum security market, which QNu Labs estimates could reach $100 billion by 2035. The startup points to the "Harvest Now, Decrypt Later" threat—where adversaries collect encrypted data today to decrypt once quantum computers become available—as a driving force behind demand for post-quantum cryptographic solutions.

The company serves industries including banking and finance, telecommunications, government and defence, and automotive. QNu Labs has previously been named a global leader in Quantum Key Distribution by research firm Markets and Markets.

The fresh capital will be used to scale QNu Labs' product development and market expansion efforts as organisations worldwide begin preparing for what the company describes as "Q-Day"—the point at which quantum computing capabilities render existing encryption obsolete.
