Nexus connects the global quantum ecosystem through validated data, expert insights, and transparent matchmaking.
Nexus is a quantum communications startup building next-generation secure networking solutions for the post-quantum era. Our mission is to protect global data flows and enable resilient digital infrastructure through quantum-safe communication systems.
Growth-stage, with validated prototypes and early commercial pilots underway in defense and financial sectors.
Headquartered in London, UK, with partnerships across North America and Europe — key regions driving commercialization of quantum technologies.
Currently raising $500M USD to accelerate pilot deployments and scale commercialization.
Nexus is moving from pilot deployments toward enterprise-scale adoption. Strategic partnerships with corporates, governments, and telecom providers are central to our growth roadmap.
Seed to Series A
Nexus develops quantum-secure communication systems that protect sensitive data and critical infrastructure against emerging quantum threats. Our technology leverages a hybrid of quantum key distribution (QKD) and post-quantum cryptography (PQC), ensuring both near-term deployability and long-term resilience.
Quantum Key Distribution (QKD): Enables provably secure exchange of encryption keys using quantum states of light.
Post-Quantum Algorithms: Integrates lattice-based cryptography for interoperability with existing digital infrastructure.
AI-Driven Network Intelligence: Optimizes secure data routing and minimizes latency in complex communication environments.
Currently at TRL 6–7: validated prototypes demonstrated in relevant environments, with pilot deployments underway in defense and financial sectors.
Hybrid approach combining QKD + PQC for both practicality and future-proofing.
Designed for scalability across telecom, enterprise, and government networks.
Integration-first model, enabling adoption without full infrastructure replacement.
National Security & Defense: Ultra-secure channels for mission-critical communications.
Finance & Risk Management: Protection of high-value transactions and sensitive data.
Healthcare & Life Sciences: Secure exchange of medical records and biomedical research.
Energy & Infrastructure: Safeguarding smart grids and distributed energy systems.
Pre Seed
Nexus has secured $29M USD through a combination of seed investment, grants, and strategic partnerships, enabling us to advance prototypes, validate core technology, and establish early commercial pilots.
We are currently raising $500M USD to accelerate product deployment, scale operations, and expand into new markets.
Technology Development: Further optimization of QKD/PQC hybrid architecture and expansion of pilot-ready systems.
Commercialization: Scaling customer pilots in defense, finance, and healthcare sectors.
Talent & Infrastructure: Building a multidisciplinary team and strengthening our secure infrastructure backbone.
Strategic Partnerships: Deepening collaborations with telecom providers, enterprises, and government stakeholders.
The funding from this round positions Nexus for Series A growth, targeting global expansion and establishing leadership in the quantum communications market over the next 3–5 years.
