ZERO X FOURTEEN LTD

What ZERO X FOURTEEN LTD does

Zero X Fourteen Ltd (DBA: 0x14) is a UK-based telecom network consulting firm headquartered in Wembley, Middlesex, founded by Josip Duricic, a self-described "99x engineer" with 20+ years of hands-on telco and IT experience spanning ISP network construction and CTO-level operations across multiple operators. The company is organized around three service pillars: BUILD (carrier-grade network design and deployment from greenfield to integration), COMPLY (ETSI TS 102.232-aligned lawful intercept and data retention architectures), and OPTIMISE (deep-dive diagnostics and performance tuning across multi-vendor stacks). Technical depth spans L1–L7 across routing (BGP, EVPN, BNG, CGN), signalling (SS7, SIP, IMS), policy and charging (PCRF, PCEF, OCS), and mediation/OSS/BSS, with hands-on integration across Cisco, Arista, Huawei, and Juniper platforms, plus custom software work in Python, C/C++, and CUDA on Linux/FreeBSD.

The firm delivers professional services rather than a packaged software product, and its go-to-market is direct and selective: a minimal content website, no intermediaries, no marketing channels beyond inbound contact, and an explicit filter on project fit ("only interested in projects worth waking up for"). The target customer segment is telecom operators and carriers requiring carrier-grade infrastructure, multi-vendor integration, regulatory compliance for lawful intercept and data retention, or complex performance diagnostics — all engagements where uptime and protocol correctness are critical. The company states worldwide availability and a global track record, though only the UK headquarters is disclosed. No pricing, headcount, revenue, funding, partnerships, certifications, or named customers are publicly disclosed.

Commercially, the model is project-based consulting revenue from senior-led engagements, with the founder's personal credentials and domain specialization serving as the primary value driver. The combination of regulatory specialization (ETSI compliance), multi-vendor interoperability expertise, and the ability to write custom glue software for unusual network environments positions the firm as a high-skill boutique rather than a scalable platform, with revenue scale inherently bounded by the founder's available capacity and the absence of disclosed additional headcount or institutional backing.
