Sigicom develops and delivers autonomous measurement systems for vibration, noise and other environmental disturbances in infrastructure and construction projects, supported by a cloud platform for monitoring, reporting and regulatory compliance.
About Sigicom Operations
Sigicom is a private, independent technology company founded in 1981 that develops and supplies complete systems for environmental monitoring in construction and infrastructure projects. The company focuses on measuring vibration, noise and other environmental disturbances generated by blasting, piling, excavation, tunneling and heavy traffic. Customers include contractors, consulting engineers, asset owners and public authorities that need to document environmental impact and demonstrate compliance with applicable standards and permit conditions.
The core offering is the INFRA system with autonomous vibration and noise sensors, data loggers, communication units and a web platform for data collection, analysis and reporting. The solution is used in projects such as metro systems, railways, road and bridge construction and urban development where requirements for continuous monitoring of environmental impact are high.
Sigicom Business Model
Sigicom operates a business model that combines sales of proprietary hardware with recurring revenues from software, services and support. The company designs and manufactures sensors, loggers and accessories that are sold to customers globally, often as part of complete monitoring systems for long term field deployments. The hardware is engineered for robust operation in demanding outdoor environments, with long battery life and remote configuration capabilities that reduce the need for site visits.
In addition to equipment sales, Sigicom provides cloud based access to the monitoring database through INFRA Net, where customers can configure measurements, follow ongoing projects, generate reports and share information with clients and regulators. The company also offers calibration, training, technical support and equipment rental, which create recurring revenue streams and support long term customer relationships.
Growth and Development
Sigicom has gradually expanded its geographical presence outside Sweden and the Nordics through subsidiaries in markets such as France, the United Kingdom, the United States, Canada, Denmark and the Netherlands. International growth is driven by increasing requirements for documented environmental monitoring and by a growing need for cost efficient, automated measurement solutions in large and complex infrastructure projects.
The company invests continuously in product development, including wireless communication, energy efficient electronics, data storage and user interfaces. New generations of sensors and loggers are developed to simplify installation and operation, improve data quality and support more extensive remote monitoring. In parallel, the digital platform is further developed to support standardized report formats, project management and integration with customers’ internal systems.
Market and Competition
Sigicom operates in a specialized global market for environmental monitoring linked to the construction and civil engineering sector. Demand is influenced by infrastructure investment levels, urbanization, dense urban development and tightening regulations related to vibration, noise and other disturbances. In many countries, authorities require measurement and reporting to protect nearby buildings, infrastructure and people during construction activities.
The competitive landscape includes international suppliers of vibration and noise monitoring equipment, traditional instrument manufacturers and local rental and consulting companies that provide monitoring services. Sigicom positions itself as a system provider focused on complete, autonomous solutions for long term field monitoring where hardware, software and support are delivered as an integrated offering.
Technology and Differentiation
Sigicom’s technology platform is based on proprietary vibration and noise sensors, data loggers and communication units designed for unattended operation in the field over extended periods. Examples include triaxial geophones and noise monitors that comply with relevant standards, embedded digital signal processing and integrated communication modules that transmit data to INFRA Net without manual handling. The engineering focus is on reliability, low power consumption and rugged design suitable for harsh site conditions.
INFRA Net aggregates measurements from multiple units and projects into a single cloud platform where users can configure alarm thresholds, follow measurements in near real time, analyze historical data and create standardized reports. The system supports regulatory frameworks and limit values, which simplifies documentation towards clients, regulators and other stakeholders. The combination of in house hardware and software gives Sigicom control over the full chain from sensor to report.
Ownership and Capital Structure
Sigicom is a privately held, non listed company. The ownership base consists of founders, key employees and institutional investors. The company finances its operations through cash flow from the underlying business and shareholder capital, and has over time continued to invest in product development, international expansion and organizational capacity.
For investors evaluating a potential future listing, relevant focus areas include the scalability of the international business, the share of recurring revenues from software and services and the company’s ability to continue developing technical solutions that address increasing requirements for documented environmental monitoring in major infrastructure and construction projects.

Sigicom is an unlisted company, meaning the shares are not traded on any exchange. Instead, transactions take place through direct transfers between parties, known as secondary trading, typically via a specialised platform for unlisted shares such as Accumeo. For larger international companies, investing through fund structures that pool several investors into a single ownership vehicle is also common. This allows smaller minimum investments and opens up access to international companies for non-institutional investors.
Yes, it is possible to buy existing shares in Sigicom through secondary trading. On Accumeo you create a free account, submit an expression of interest with an amount and any conditions, and may then be matched with a seller. Once both parties have signed the customer agreement, a share transfer agreement is drawn up covering price, share count, and settlement date.
Yes, secondary trading is often the only realistic route to liquidity for an unlisted holding before an IPO or acquisition. Via Accumeo you submit an expression of interest with a share count and target price, and a match may be made with a potential buyer. The sale is executed through a share transfer agreement and registered either via Euroclear or directly in the company's share register, depending on how ownership is administered.
Unlisted companies have no continuous share price because there is no continuous exchange trading. The value is instead based on the latest secondary-market trade or on the price per share from the most recent share issuance. Accumeo shows both historical transaction prices and current bid/ask quotes, providing a combined reference point for pricing.
The value of an unlisted share is most often based on the latest trade — the price buyer and seller agreed in a transaction — or on the latest funding round, where the company and its investors agreed a price for the newly issued shares. These are the reference points shown on Accumeo's platform. It is, however, important to form your own view of value by examining the company's prospects. Financial reports, growth opportunities, market position, and comparable transactions in the sector all help to build a better picture of how the business may develop. Useful information can be found on the company's own website, via Accumeo's platform, and on services like allabolag.se.
No, Sigicom is an unlisted company and its shares are not traded on the Stockholm Stock Exchange, NYSE, or any other regulated marketplace. Shares are instead traded through secondary trading between investors, typically via a specialised platform such as Accumeo.
Yes. Shares in Sigicom can be delivered to an ordinary securities account with a broker such as Avanza or Nordnet, and are registered as the transaction completes.
We hold no registered transfer restrictions for Sigicom. The articles of association are what decide this, so read them before placing an order — restrictions can be added without showing up in public sources.
