What NuBlue does

Nublue Ltd is a UK-based managed cloud and infrastructure provider founded in 2003 and headquartered in Lancaster with a second office in Manchester. Operating as the hosted-infrastructure arm of CTI Holdings Group (a diversified digital agency parent that includes CTI Digital, Silverchip, Mosquito Digital, Stardotstar, and Supercharged Commerce), Nublue delivers fully managed services on AWS — including EC2, RDS, S3, VPC, and IAM management — combined with Cloudflare Enterprise CDN and security, Platform.sh-based PaaS, and NVIDIA GPU infrastructure for AI workloads.

The portfolio spans WordPress Hosting (£50-£315/month tiers), PCI-compliant eCommerce Hosting for Magento, WooCommerce, and Shopware (£75-£350/month), Application Hosting for Drupal/Umbraco/Laravel, and reseller/agency hosting (£200-£450/month). In 2024 Nublue extended into AI infrastructure with managed GPU Hosting and a Private LLM Hosting platform that deploys open-source large language models inside customer AWS environments or on-premise NVIDIA appliances for data-sovereign use cases. Cross-cutting services include security (Tenable vulnerability scanning, WAF, DDoS, MFA), migrations and AWS health-checks, and disaster recovery.

Revenue is generated primarily through recurring monthly and annual subscriptions across managed hosting tiers, supplemented by quote-based multi-year enterprise contracts for GPU/Private LLM deployments and project-based professional services for migrations and AWS audits. Nublue's documented customer base is weighted toward UK public sector and regulated enterprises — British Council, VisitBritain, Department of Health & Social Care, Uniper, Maze Living — with a secondary channel serving digital agencies and resellers through white-label plans. Distribution runs through direct enterprise sales, inside sales via website quote requests, and the CTI group referral network, and Nublue holds ISO 27001 (2021), ISO 9001, Cyber Essentials, and AWS Solution Partner and G-Cloud 13 supplier credentials that materially shape its addressable market.
