What Secqai does

SECQAI (legal entity SECQAI LTD) is a privately-held UK semiconductor company, headquartered in London with additional engineering offices in Bristol and Bengaluru (India, opened April 2026). It designs and develops memory-safe, post-quantum cryptography-enabled Trusted Platform Module System-on-Chips (the Q-Locked product family), sold to OEMs across server, AI/HPC data centre, edge/IoT and Critical National Infrastructure markets, with an explicit dual-use focus on governments and defence (notably NATO). The flagship is the SE01 Q-Locked CHERI TPM SoC — a RISC-V implementation of the CHERI ISA v9 memory-safety architecture pioneered by the University of Cambridge and SRI International, integrating hardware-accelerated NIST PQC algorithms (FIPS 203, 204, 205), designed towards FIPS 140-3, and taped out on TSMC's 22nm process via VCA IMEC in November 2025. The product family is delivered in server TPM, edge device TPM and custom PCB integration variants, with an optional ultra-low power Quantum Random Number Generator.

The company operates a hybrid revenue model combining semiconductor hardware sales (Q-Locked SoCs) with professional services (custom PCB design and integration) and significant non-dilutive grant co-funding (Innovate UK, DESNZ, NATO DIANA, ChipStart UK). Go-to-market is OEM-embedded: direct enterprise engagement with OEMs and integrators, supplemented by a global channel partnership with Boston Limited. Distribution is supported by a PR-driven, content-led marketing motion (insights blog, PR agency Flame PR, student SNN competition) and credibility signals from membership in NATO DIANA, ChipStart UK, Plexal Cyber Runway, techUK Quantum Security Working Group, NVIDIA Inception and Ansys startup programmes. Beyond the core secure-silicon business, SECQAI has built a separate research line in quantum-assisted AI — launching what it describes as the world's first hybrid Quantum Large Language Model (QLLM) in February 2025, trained on a proprietary in-house quantum simulator, with select-partner private beta access; this remains pre-commercial and is not the primary revenue driver. Headcount is 1-10, the company is founder-led by CEO Rahul Tyagi, and funding to date has been almost entirely non-dilutive, with no disclosed venture capital investment.

Revenue model

1. Semiconductor hardware sales: Sale of SE01 "Q-Locked" TPM SoCs to OEMs across server, AI/HPC data centre, edge device and IoT markets. Designed to be commercially scalable (taped out on TSMC 22nm with industry partner).
2. Custom PCB design and integration services: Collaborative customisation of Q-Locked TPM on customer PCBs — working directly with customers and their partners, or introducing customers to SECQAI's PCB supplier ecosystem, for tailored deployment.
3. Government / grant co-funding (non-dilutive): Co-funding secured from Innovate UK (Feasibility Studies in Quantum Computing), DESNZ (AI for Decarbonisation Programme / Net Zero Innovation Portfolio), NATO DIANA Phase I (€100,000) and Phase II (up to €300,000). Acts as non-dilutive capital supporting R&D.

Core offering

Secqai designs and sells the Q-Locked System on Chip (SoC) family — memory-safe semiconductors that combine the CHERI ISA v9 capability architecture on RISC-V with hardware-accelerated NIST Post-Quantum Cryptography (FIPS 203/204/205). Its flagship commercial realisation is the SE01 "Q-Locked" CHERI TPM, taped out on TSMC 22nm, delivered as Server TPM, Edge Device TPM and custom PCB integrations for OEMs, governments, defence and Critical National Infrastructure customers. The company also develops quantum software including a hybrid Quantum Large Language Model (QLLM) and an in-house quantum simulator.

Product overview

Secqai offers a dual-use hardware-and-software portfolio rather than a single product. The flagship offering is the Q-Locked System on Chip (SoC) family — secure semiconductors that combine memory-safe architectures (CHERI ISA v9 on RISC-V) with hardware-accelerated Post-Quantum Cryptography (FIPS 203/204/205). The first commercial realisation is the SE01 "Q-Locked" CHERI TPM, taped out with TSMC on 22nm and deployed as a Root of Trust in three form factors: Server TPM (for on-premises and AI-enabled HPC clusters), Edge Device TPM (for IoT/remote endpoints), and Custom PCBs (bespoke integration via Secqai's PCB supplier ecosystem). An optional Ultra-Low Power Quantum Random Number Generator provides quantum entropy for highly constrained environments. On the software side, Secqai has built the world's first Quantum Large Language Model (QLLM) — a hybrid quantum/classical LLM that incorporates a quantum attention mechanism, trained on its in-house vectorised Quantum Simulator. The SE01 TPM was recently demonstrated powering the world's first PQC in a Firmware Over The Air (FOTA) update process on a memory-safe chip.
