PREDUZECE ZA TELEKOMUNIKACIJSKE USLUGE REALAIZ DOO BEOGRAD (SAVSKI VENAC)

Their core work

Realaiz is a Belgrade-based telecommunications SME that provides ICT and communication solutions for critical infrastructure sectors — energy grids, transport networks, and border security. Across their H2020 portfolio, they contribute telecom expertise to projects securing smart grids, making transport infrastructure resilient to extreme events, enabling border surveillance in harsh environments, and building TSO-DSO market interfaces. Their consistent thread is applying telecommunications and data management capabilities to infrastructure challenges where reliable communication and sensing are essential.

What they specialise in

How they've shifted over time

Realaiz entered H2020 in 2018 across multiple domains simultaneously — transport resilience (RESIST), border surveillance (FOLDOUT), and smart grid security (SPEAR) — all as a third-party subcontractor. By 2019, they shifted to direct participation in energy-focused projects (INTERRFACE, SDN-microSENSE), suggesting a strategic pivot toward electrical grid communications and energy market platforms. The move from third-party roles to full participant status, combined with the keyword shift toward grid services, network codes, and wholesale markets, signals a maturing focus on energy-sector ICT.

Realaiz is converging on energy-sector ICT — expect them to pursue smart grid, energy data management, and grid digitalization projects as a direct partner rather than subcontractor.

How they like to work

Realaiz started as a third-party contributor (3 of 5 projects) before graduating to full participant roles, indicating they built credibility through subcontracting and then secured direct consortium positions. With 121 unique partners across 25 countries, they operate within large European consortia rather than leading them. Their broad but shallow network suggests they are brought in for specific telecom capabilities rather than serving as a consortium hub.

Despite being a small Serbian SME, Realaiz has touched 121 partners across 25 countries through large-scale EU consortia — a remarkably wide network for a company with just 5 projects, reflecting the size of the consortia they join rather than deep bilateral ties.

What sets them apart

Realaiz occupies a niche as a Serbian telecom SME that bridges ICT and critical infrastructure sectors — a combination uncommon in the Western Balkans H2020 landscape. Their ability to contribute across energy, transport, and security projects makes them a versatile ICT partner for consortia needing telecommunications expertise applied to infrastructure challenges. For coordinators building proposals with Western Balkans representation, they offer proven H2020 experience across multiple pillars.

Highlights from their portfolio

• INTERRFACE
  Their largest funded project (EUR 384,256) and a direct participant role, focused on the complex TSO-DSO-Consumer interface for pan-European energy markets.
• SDN-microSENSE
  Demonstrates their energy-sector pivot — a direct participant role in microgrid cybersecurity, combining their telecom and security strengths.
• FOLDOUT
  An unusual application — through-foliage detection for border surveillance — showing the breadth of their sensing and communication capabilities.
