What AllSpark does
AllSpark OÜ is an Estonian technology and engineering services company founded in 2017 that delivers end-to-end infrastructure technology services for railway, telecommunications, and energy projects, with primary concentration in Estonia and selected work in the wider Baltic region. The firm organizes its offering into three integrated service lines — Design and Engineering, Construction and Integration, and Maintenance and Operations — covering the full infrastructure lifecycle from initial design and risk assessment through owner supervision to preventive and corrective maintenance. Its technical core is railway command control and signaling (CCS) and interlocking systems, railway catenary network design, telecommunications infrastructure, operational technology and automation, and energy solutions spanning low, medium, and high voltage.
The company operates on a project-based professional services revenue model, with customer acquisition driven by direct enterprise and government sales outreach rather than self-service or channel distribution. It has executed 200+ projects for a concentrated set of anchor customers including the Estonian Railway Infrastructure manager (EVR), the Rail Baltic Harju I program, Telia, Utilitas, Enefit Connect, Elektrilevi, and the new Tallinn Hospital. Differentiators cited are full lifecycle coverage, deep specialization in safety-critical railway signaling and interlocking, and cross-sector synergy across railway, telecom, and energy infrastructure. AllSpark is privately held, founder-owned, headquartered in Tallinn, holds ISO 9001 and ISO 14001 certifications, and discloses 5+ M€ annual turnover on its corporate website.

AllSpark product offering
Product offeringCore offering
AllSpark provides end-to-end infrastructure technology and engineering services across railway, telecommunications, and energy sectors. The company delivers the full project lifecycle—from design, engineering, and construction through integration, maintenance, and owner supervision—with deep specialization in safety-critical railway signaling (CCS) and interlocking systems, railway catenary networks, telecommunications network buildout, and low-to-high voltage energy solutions including substation design.
Product overview
AllSpark is a technology and engineering services company offering end-to-end infrastructure services organized into three integrated service lines: Design and Engineering Services (covering telco/IT solutions, railway signaling and interlocking, railway catenary networks, operational technology and automation, and energy solutions), Construction and Integration Services (covering telco infrastructure, railway systems, and security/low voltage solutions), and Maintenance and Operations Services (including turnkey lifecycle management with preventive and corrective maintenance). These three service lines work together to provide lifecycle coverage for railway CCS (Command Control Signaling), telecommunications, and energy infrastructure projects.
