What Citrus Solutions does

SIA Citrus Solutions is a Latvian design and construction company headquartered in Riga that delivers full-lifecycle engineering services for complex infrastructure projects. Founded in 2005 and operating with 330+ employees, the company operates five integrated service lines: design and research, building engineering systems (HVAC, electrical, BMS, fire safety), strategic sites and data centers (including Uptime Institute TIER III certified facilities), external engineering networks (fiber optic, power, telecommunications, border surveillance systems), and ongoing maintenance. Its service model is built on single-point responsibility from initial concept through construction and ongoing support, removing the coordination burden that arises when multiple contractors are involved.

The company serves primarily Latvian government institutions and large enterprises, generating €117M in 2025 revenue through project-based contracts awarded via public procurement and direct enterprise sales. Key customers include LVRTC (283.6 km Latvia-Russia border surveillance infrastructure), VID (customs control point video surveillance across 32 servers and 24 locations), telecom operators such as Tet and Lattelecom (the DATTUM TIER III data center), Rail Baltica consortium partners, and healthcare operators including the Children's Hospital and Latvian Oncology Centre. The company also maintains a wholly-owned German subsidiary, Citrus Solutions GmbH, in Etzelwang, signaling initial geographic expansion beyond Latvia.

Citrus Solutions' business model is project-driven, with revenue generated from professional services contracts (design, construction, installation) supplemented by recurring maintenance revenue from installed engineering systems. Multi-year contract cadence dominates, and the company differentiates on regulatory clearances for sensitive government infrastructure, TIER III certification capability, and an integrated delivery model that competes against fragmented multi-vendor alternatives. To date, the company has completed 1500+ projects for 180+ clients, with notable programs spanning maritime observation (2006-2008), data centers (2012-2013), customs surveillance (2017-2019), Rail Baltica external networks (2020-2023), and current border surveillance (2024-2026).
