What STONESTHRO LTD does

Stonesthro Ltd is a UK-based, privately held SME founded in 2022 that provides sovereign microedge cloud computing infrastructure under the True Edge Cloud ("microscaler") brand. Its platform delivers AI-ready, geo-resilient distributed compute with access to 15,800+ UK sites through a strategic partnership with Cornerstone, offering sub-5ms latency, N+3/N+4 availability configurations, a PUE as low as 1.02, and zero-trust security architecture. The core product suite comprises IaaS and PaaS services — CPU-as-a-service, GPU-as-a-service (NVIDIA-optimised) for AI/ML workloads, Kubernetes-as-a-service, Docker container support, Linux/Windows servers, and Object/Block/File storage — augmented by optional advanced security services (virtual firewall, anti-malware, DDOS protection, SOC/SIEM). All infrastructure is positioned as UK-owned and operated under UK law, with explicit Procurement Act advantages for public sector buyers.

The company monetises via quote-based enterprise contracts on multi-year terms, blending managed services, usage-based GPU/CPU consumption, and recurring subscription revenue for storage and security. Go-to-market is direct enterprise field sales targeting six primary verticals: Smart Manufacturing, Financial Services, Healthcare, Media and Entertainment, Justice, and Government. Distribution is supported by a technology partner ecosystem of more than 12 named partners (Cornerstone and Zadara as flagship/core, plus Neurosyn for healthcare AI and AMP, G2N, Ontix, Plexa, Sapphire, SiteHop, Slicefinity, Timebeat, and Zave IT), plus content marketing, industry events such as Tech Show London, and earned media recognition including STL Partners' 50 Edge Computing Companies to Watch in 2026 and a 2025 Cloud Solution of the Year award. Stonesthro holds Cyber Essentials and ISO 9001:2015 (Certificate No: 508992026) certifications, and its operating geography is exclusively the United Kingdom. Leadership comprises CEO Ashley Sellar, CTO Gregg Mearing, CISO Andy Bates, and CRO Mark Hua.

Expansion highlights5 records

Broad incumbents

• Amazon Web Services (AWS): Global hyperscale cloud provider with UK regions and growing edge capabilities; competes with Stonesthro across IaaS, PaaS, and AI workloads but lacks the sovereign microedge positioning.
• Google Cloud: Hyperscale cloud provider with UK presence and AI/ML infrastructure; competes for enterprise compute and AI workloads but does not match Stonesthro's sovereign edge distribution.
• Equinix: Global colocation and interconnection provider with extensive UK data centre footprint; broader scope than Stonesthro but adjacent in providing distributed infrastructure for low-latency enterprise workloads.
• Microsoft Azure: Global hyperscale cloud platform with UK data centres and extensive enterprise/government footprint; competes for the same regulated UK workloads that Stonesthro targets.

Emerging players

• Nscale: UK-focused AI cloud infrastructure provider offering GPU compute for AI/ML workloads; directly comparable to Stonesthro's GPU-as-a-Service edge offering within the UK sovereign market.
• Platform9: Managed Kubernetes and cloud-native platform provider; overlaps with Stonesthro's Kubernetes-as-a-Service and cloud-native enablement capabilities for distributed infrastructure.

Direct peers

• Vapor IO: US-based provider of micro-edge data centres and edge cloud services with a distributed architecture similar to Stonesthro's microscaler model, targeting low-latency AI and IoT workloads.
• EdgeConneX: Global edge data centre operator offering distributed infrastructure for cloud, content, and AI workloads; directly comparable to Stonesthro's distributed microedge positioning.
• Civo: UK-based cloud provider offering managed Kubernetes and cloud services with a sovereign UK focus; comparable to Stonesthro's UK-regulated, enterprise-focused positioning.
• Zadara: Provider of fully managed, distributed cloud infrastructure services (compute, storage, GPU); a strategic partner of Stonesthro and a direct competitor in managed edge cloud delivery.
