What pQCee does
pQCee Pte Ltd is a Singapore-based deep-tech software startup founded in 2022 that builds a suite of post-quantum cybersecurity products and services designed to protect data and communications against both classical and future quantum attacks. The company operates a Crypto-agile Defence-in-Depth (CADD) framework covering data-in-motion, data-at-rest, and identities. Its product portfolio includes SafeQuard (NIST FIPS 203 ML-KEM-based end-to-end encryption for web pages, emails, and enterprise data), QKDLite (middleware bridging HSMs to QKD networks supporting ETSI QKD 014, PKCS#11, FIPS 197/203/204, PCI-DSS), inoQulate (quantum-safe PDF/document signing using patent-pending Signature Pre-image Proof / MPC-in-the-head technology), PacketQC (cryptographic inventory and post-quantum migration governance), QuICScript (browser-native 20-qubit quantum simulator used by Institutes of Higher Learning), and AStablish (zero-knowledge-proof-based digital asset ownership verification). In March 2026 the company launched what it describes as the first crypto-agile Windows CNG provider supporting both NIST FIPS204 (ML-DSA) and FIPS205 (SLH-DSA).
The company monetizes through a combination of subscription and enterprise licensing on the Microsoft Azure Marketplace, direct enterprise sales, and channel/distributor partnerships (Netrust as global solutions partner, Pacific Tech for Singapore, Malaysia, Thailand, Cambodia, and Indonesia). Target customer segments are banking and financial services, government and public sector, healthcare, and critical infrastructure — all of which require long-term confidentiality and are exposed to harvest-now-decrypt-later risk. Go-to-market is enterprise field sales augmented by product-led growth (free demos of SafeQuard and PacketQC Discovery). The company has received up to S$1M in non-dilutive funding under CSA's CyberCall 2023 CCDF program, passed an EY security assessment with zero critical/high/medium vulnerabilities in 2025, and is a signatory of the Quantum Ecosystem MOU at GovWare 2025 alongside NCS Group, IBM, PQShield, Thales, and QIZ Security.
pQCee is a privately held Singapore private-limited company co-founded by Dr. Tan Teik Guan (CEO; PhD from SUTD) and Loh Chay Hiah (CFO), with academic and business advisory support from Prof. Jianying Zhou and Ad Ketelaars respectively. The firm is small (1-10 employees) and operates from 7 Temasek Boulevard, Singapore, with a US beachhead established in 2025 via the Maryland Department of Commerce Global Gateway Soft Landing Program at bwtech. Ownership is founder-led with no disclosed institutional venture or private equity backing; the company is closely engaged with Singapore government and ecosystem programs (CyberSG TIG Collaboration Centre, Enterprise Singapore, Maryland Department of Commerce) and pursues a patent-pending proprietary technology (SPP) as a core differentiator.
