pQCee Pte Ltd, a Singapore-based provider of quantum‑safe cybersecurity technologies, today announced that it has raised US$3.9 million in its latest Seed funding round. The round was co‑led by SGInnovate and Lotus One Investment, with participation from In Group Holdings, Wavemaker Ventures, SUTD Venture Holdings, and Apsara Investments.
This marks pQCee’s second institutional funding round, following an initial US$2.8 million raise in 2022 co‑led by Wavemaker Ventures and SEEDS (arm of SG Growth Capital, the investment platform of EDB and Enterprise Singapore), with participation from SGInnovate, Mirana Capital, Paragon Capital Management, and Apsara Investments. The earlier round supported the development of pQCee’s flagship products, including SafeQuard and QKDLite, which are used to mitigate against harvest-now-decrypt-later quantum threats.
“This funding enables us to accelerate our mission of making quantum‑safe security easy to deploy and hard to break. As global regulations tighten and the threat landscape evolves, organisations need practical, interoperable solutions they can adopt today. We are grateful for the trust of our investors and partners as we scale our team and expand globally,” said Dr Teik Guan Tan, CEO, pQCee.
pQCee’s technology portfolio is headlined by SafeQuard, which provides end-to-end encryption to neutralise ‘harvest-now-decrypt-later’ attacks, and QKDLite, a sophisticated middleware for key management that adheres to standards such as PKCS#11, ETSI QKD 014 and FIPS 203.
pQCee’s portfolio of solutions also extends to inoQulate for post-quantum PKI certificates, and the QuICScript tool, which uniquely enables users to experience a 20-qubit quantum simulator directly within their browser. By integrating these solutions—alongside specialised capabilities like ownership assurance for digital assets and quantum-safe Web3 protections—pQCee aims to help enterprises transition securely to quantum-resilient environments.
pQCee has collaborations with Thales and Feitian, with the integration of pQCee solutions with their hardware security modules and secure devices; Netrust and SendQuick, to extend quantum‑safe protection into digital identity, messaging, and enterprise workflows; and PQShield, to ensure alignment with the latest post‑quantum cryptographic standards. The company has also partnered with Microsoft and TechCreate to support deployment of crypto-agile cybersecurity.
With the new capital, pQCee will expand its team in Singapore, deepen its presence across Asia, and accelerate entry into the United States, Europe, and the Middle East. The company is scaling to meet growing global demand for quantum‑resilient security infrastructure as organisations prepare for the post‑quantum era.
“As Q-day rapidly approaches due to advances not just in quantum but also in AI and materials, companies and governments are becoming more aware of the threat this poses to existing systems. We see pQCee playing a role in providing a solution to this problem, and are delighted to continue supporting Dr Tan and his team as they scale their solution to the global stage. Dr Tan is of course no stranger to us. We were investors in his first cybersecurity startup, and investing in his second venture was an obvious thing to do for us,” said Hsien-Hui Tong, Executive Director – Investments, SGInnovate
“The best infrastructure companies solve problems before the market fully recognizes them. Quantum-safe security is one of those rare opportunities. By the time quantum risk becomes everyone’s priority, the category leaders will already be built. We look forward to supporting their expansion into new markets,” said Nirmal Singh, Chairman Lotus One Investment
“Today’s encryption methods will no longer be secure in a post-quantum era, making investment in quantum-safe solutions a necessity, not an option. pQCee’s holistic suite of solutions simplifies post-quantum cryptography (PQC) migration for enterprises, reducing complexity in integration, procurement, and cost. As regulations globally mandate critical systems to complete PQC migration by as early as 2030, we believe pQCee, backed by its founding team’s expertise, is well-positioned to capture early demand,” said Paul Santos, Co-founder and Managing Partner, Wavemaker Partners.
