1GLOBAL Tech Stack

Global eSIM and connectivity platform connecting devices, people, and enterprises

Telecommunications Amsterdam 501–1,000 employees Founded 2006 Privately Held

1GLOBAL operates a multi-layered telecom infrastructure spanning eSIM provisioning, cloud connectivity, and IoT routing across five continents. The tech stack reveals heavy containerization work (Kubernetes adoption, hardening, service mesh architecture) paired with acute security focus (ten active security hires, multiple hardening projects, CI/CD automation in flight) — a pattern typical of companies scaling mission-critical network infrastructure from monolith to distributed cloud. Finance headcount scaling alongside engineering signals operational strain from rapid customer acquisition.
