Platform
The network inventory platform, built on the world’s leading geospatial engine.
MarlinDT turns Esri ArcGIS into a true digital twin for telecom and utility networks. We build the high-quality network inventory — the data model, the multi-user CRUD at scale, the telecom-native tools — and rely on ArcGIS for world-class geospatial. The result is one connected platform, on web, mobile and desktop, that brings your whole organisation to a single source of truth.

Web, mobile and desktop — for everyone who touches the network
One platform, three surfaces, every role:

Field technicians
Mobile and offline survey, acceptance and as-built capture — the crew works from the truth, even with no signal.

Designers
High-output, rule-based design at scale on the desktop, with versioning and locking — without ever touching production.

The business
Web dashboards and real-time KPIs for planning, leadership and investors.

Everyone, integrated
A strong API ties MarlinDT to the rest of your stack — survey tools, dashboards, PM software and more.
A connected platform, not an island
Because MarlinDT is built on ArcGIS and integrates with it natively, you inherit the entire ArcGIS ecosystem. We don't rebuild what already exists — we connect it, and keep one source of truth at the centre.

Through best-in-class ArcGIS mobile tooling (VertiGIS Studio Mobile), tailored to your workflow.

Bring in automated high- and low-level designs and turn them into a maintainable inventory.

Any ArcGIS dashboard or analytics tool can read MarlinDT data.

Transactional, bulk and streaming APIs connect everything else.
