A Team That Understands Telecom From the Inside
We build billing, OSS, and network software for telecom companies, using the same cloud native engineering practices we had to adopt ourselves to keep up with the systems we run.
Our Story
This company did not start with a framework or a methodology. It started with real telecom systems that needed to work: billing platforms, product catalogs, network integrations, built the way most software was built a decade ago. Single applications, manually managed servers, and releases that took a planning meeting just to schedule.
Over time, that stopped being good enough. Systems got harder to change, harder to scale, harder to trust in production. So we rebuilt how we work. We moved to microservices, containerized everything with Docker, put Kubernetes underneath it, automated releases with CI/CD, and started actually watching our systems in production instead of finding out about problems from a customer complaint.
We bring that same shift to the telecom companies we work with now, at the scale enterprise operators actually need.
What We Believe
Software Should Get Easier to Change Over Time, Not Harder
A system that was simple to launch but impossible to modify two years later was never actually simple. It just deferred the difficulty. We would rather do the harder work upfront so the next five years of changes are easy ones.
A Vendor Who Disappears After Go-Live is Not Really a Partner
Long term support is not an upsell for us. It is the point of working with us at all. We stand behind our architectures, run real telemetry monitoring, and stay engaged to support reliability, optimisation and ongoing engineering improvements.
Our Team
Our engineering is led by people who have built billing, OSS, and network integration systems for telecom operators in multiple countries, including deep, hands on experience with protocols like Diameter and RADIUS, not just the application layer sitting on top of them.
That combination, real telecom protocol depth alongside modern cloud native engineering, is something most vendors in this space simply do not have.
Low-level AAA and packet inspection experience for prepaid and postpaid charging protocols.
Working with modern telecom standards and 5G ecosystem integrations where relevant to client requirements.
Containerized deployments with automated scaling and blue-green canary rollouts.
Standardized catalog, order, and billing APIs eliminating proprietary silos.
Lalu Kalsariya
Horizon Telco Labs is led by a practical engineering mindset shaped by telecom systems, cloud-native modernization, and standards-aligned platform thinking. The focus is on helping telecom and technology teams build systems that are easier to operate, easier to evolve, and better aligned with long-term delivery needs.
From billing and OSS modernization to APIs, cloud-native platforms, and observability, the emphasis remains on maintainable engineering, real delivery support, and technology decisions that continue to work after go-live.
Where We Work
Representative delivery experience across multiple telecom environments and regions shapes how we think about integration, standards alignment, and practical engineering execution from the start of a project.
