Gamma Tech Stack

Unified communications and connectivity platform for European SMEs and enterprise

Telecommunications London, England 1,001–5,000 employees Public Company

Gamma is a London-listed telecom operator delivering voice, unified communications, mobile, and connectivity across the UK, Germany, Spain, and Benelux. The tech stack (Microsoft 365, WebRTC, Cisco, SD-WAN, AWS, Kubernetes) reflects a hybrid infrastructure play—blending carrier-grade networking with cloud-native application delivery. Active hiring leans engineering-heavy (25 roles) against sales (15), suggesting product-led capability expansion; concurrent pain points around quote-to-cash, incident management, and supply-chain risk indicate operational scaling challenges typical of mid-market telecom consolidation.
