KXCO is the software company of Knightsbridge Group. The group has operated since 1987, with presence in Bangkok, Doha, Paris and London. KXCO builds post-quantum infrastructure for corporates, licensed institutions and AI agents. Every product runs on Armature L1. Every material claim is independently verifiable.
The UK company on file is Knightsbridge Financial Ltd, England & Wales, Company No. 15684975, incorporated 27 April 2024. LEI 213800TMP5DQFDKOZ549. ICO registration C1961692. Group counsel is Knightsbridge Law. KXCO does not custody assets and holds no financial licence.
Leadership and advisory experience includes people who have worked at BlackRock, Fidelity Investments, DTCC, Bear Stearns, Capgemini, and Knightsbridge Group. Those names describe rooms our advisors have sat in. They are not clients, not investors, and not endorsement marks.
Economist with 40 years in global capital markets, with an Asia-Pacific focus. Founder of Knightsbridge Group (1987) and KXCO. Group context includes selection for the EU Commission Blockchain Sandbox in 2025. The conviction that post-quantum cryptography must become the foundational layer of financial infrastructure, not a retrofit, is the organisation's reason for existing. KXCO builds the infrastructure regulated institutions will need to meet post-quantum migration obligations, on architecture that will still be valid when quantum computers become cryptographically relevant.

KXCO is a UK and US software company. It builds post-quantum infrastructure for institutions that require long-term cryptographic security, not as an upgrade to schedule for later, but as a structural property of every system deployed today.
The company was founded on a single premise: the institutions that begin deploying quantum-resistant infrastructure now will complete that transition on their own terms. Those that delay will face an emergency response under regulatory pressure, with less time and less control.
KXCO does not provide custody, hold assets, or operate as a licensed financial institution. It builds the software layer that licensed institutions deploy to meet their own obligations. The infrastructure is the product. The institution is the operator.
The Armature L1 blockchain, the PQC Hosting and Bastion scanning platform, KXCO Meridian, KXCO Verified, and the KnightsVault white-label banking infrastructure are all built on the same post-quantum cryptographic foundation, NIST FIPS 203, 204, and 205.
Every signature, every credential, every deployment attestation uses ML-DSA-65 and is anchored permanently to Armature L1. There is no retrospective migration path on KXCO infrastructure. The post-quantum security is architectural, present from the first operation, and independently verifiable by any third party.
Knightsbridge Group, established in 1987 with operations across Bangkok, Doha, Paris, and London, provides the institutional foundation and capital markets experience from which KXCO was built.
Quantum migration is no longer a technology decision. It is becoming a governance, compliance, and risk-management decision, and the data being signed today may outlive today's cryptography.
Board resolutions, supply agreements, custody arrangements, and financial contracts often remain enforceable for decades. KXCO provides ML-DSA-65 signing for records with multi-decade validity, from the moment they are created, not as a future upgrade.
Audit records should remain independently verifiable regardless of vendor changes, mergers, or infrastructure migrations. KXCO anchors records to Armature L1, permanently stored and verifiable without any KXCO-controlled system remaining available.
State actors and sophisticated adversaries are capturing encrypted data today for future decryption, documented by the NSA, NCSC, and equivalent agencies. Data that must stay confidential for years should be post-quantum from creation.
As AI agents begin transacting and signing on an organisation's behalf, they need an identity verifiable without a central server. KXCO issues ML-DSA-65 agent credentials anchored on Armature L1, checkable by any counterparty, at any time.
NIST, the G7, and the NSA have transformed post-quantum migration from a future project into a present-day obligation. KXCO's cryptographic baseline is built to satisfy it from day one.
Not planned. Not roadmap. Operational today, institutions deploying KXCO operate on a compliant foundation from the first transaction.
Existing financial infrastructure remains intact. KXCO adds post-quantum signing, identity, and audit to current operations, software-only, no hardware dependency.
Built for regulated environments and built for audit. Migration advisory engagements are available now, begin the assessment and complete migration on your own schedule, before enforcement begins.
Whether you are assessing post-quantum migration risk, evaluating infrastructure for a regulated deployment, or building AI systems that require verifiable on-chain identity, the conversation begins with a direct engagement.
Stated once so it is never inferred. The group is not the filed company, and neither is a licence.
