Gamma Tech Stack

European cloud communications and unified workspace platform for business

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

Gamma is a London-listed telecom provider serving 1,000+ businesses across Europe through a hybrid sales model: channel partners for SMEs (1,500+ in the UK alone) and direct enterprise teams for larger accounts. The tech stack reveals a modern, distributed engineering operation—Java, Python, Node.js, React, Kubernetes, AWS—paired with active hiring across engineering and sales, suggesting ongoing product velocity and geographic expansion. Core pain points cluster around partner enablement (deployment proficiency, training, engagement) and bid/proposal management, indicating that channel scaling is the operational bottleneck, not technology.
