AI-Ready Infrastructure

The Transport Layer for AI in Southeast Europe

DWDM wavelengths, dark fiber, and IP transit connecting AI data centers, GPU operators, and cloud platforms across Bulgaria, the Balkans, Caucasus, and the Middle East.

The Network Problem

Why Fiber Infrastructure Matters for AI

AI at scale is a network problem, not just a compute problem. GPU clusters need massive, dedicated transport to move training data and synchronize distributed nodes across sites. Inference requires low-latency paths to deliver AI outputs to end users in real time. The fiber and wavelength layer is what makes or breaks AI performance at every stage of the workload lifecycle.

Training Workloads

Massive, Dedicated Bandwidth

GPU clusters running distributed training require massive, uncontended bandwidth for data ingest and model synchronization between nodes. Shared internet paths introduce jitter and congestion that stalls training runs and wastes expensive compute time.

Inference Workloads

Low-Latency Delivery

Real-time AI outputs — from language models to image generators — must reach end users with minimal delay. Low-latency IP transit with regional IXP presence means inference endpoints in SE Europe respond faster to users across the Balkans, Caucasus, and the Middle East.

The Markets Global Carriers Overlook

We operate in the geographic corridor where global carriers have shallow presence — providing the optical infrastructure that makes AI viable in SE Europe, the Caucasus, and the Black Sea region.

Key Asset

Caucasus Cable System

Submarine fiber across the Black Sea — the direct optical path connecting Georgia, Armenia, and the northern Middle East to European internet infrastructure. No other carrier in SE Europe operates an equivalent single-operator route on this corridor.

Who We Serve

Built for Operators, Not End Users

AI data center operators

Building or expanding data center capacity in Bulgaria and SE Europe, needing direct fiber connectivity and IP transit from day one.

Neocloud and GPUaaS providers

Regional GPU-as-a-service operators requiring high-bandwidth, low-latency transit to serve AI workloads across SE Europe and beyond.

Enterprises with data sovereignty requirements

Organizations running AI on EU data that must remain within EU borders. Our Bulgaria-based infrastructure keeps data under GDPR jurisdiction.

Caucasus and ME carriers

Carriers in Georgia, Armenia, and the northern Middle East needing protected, high-capacity paths to European AI platforms and internet hubs.

Content and cloud providers

Extending AI inference edge into Eastern Europe — reaching users in Bulgaria, the Balkans, and Black Sea markets without traversing Western European hubs.
