About Ahertaja

Ahertaja at a glance

Problem

Coordinating labour and site services on data centre projects is complex

For main contractors on large data centre and infrastructure projects, the challenge is rarely finding individual workers but managing a constantly changing mix of personnel, site management, machinery and seasonal services like winter maintenance. Instead of one partner who can scale a full site team to match project needs, contractors often rely on multiple staffing firms and subcontractors, increasing coordination effort, cost and the risk of delays or quality issues on site.

Solution

One partner for workforce and site operations on complex projects

Ahertaja acts as a single partner for personnel and construction site services on large projects, combining staffing, site management, machinery and seasonal services such as winter maintenance under one roof. The company employs and organises its own workforce, can ramp team sizes up or down in line with project schedules and provides the necessary site services to keep work progressing safely and efficiently. This allows main contractors to reduce coordination complexity, rely on one point of contact for critical site resources and focus on delivering the overall project.

 Business model

From staffed site teams to project revenue

Ahertaja generates revenue by providing workers and site services to large construction and data centre projects and charging its customers for this. Customers pay agreed hourly or daily rates for each worker, as well as fees for services such as site management, machinery and winter maintenance. The more people and services Ahertaja provides on a project, and the longer the project runs, the more revenue the company earns.

Competitors

Single partner for staffing and site services on large data centre projects

Ahertaja operates in a market with many staffing firms and construction companies that provide labour or individual services to building sites. Most of these competitors focus either on personnel leasing or on specific subcontracting tasks. Ahertaja’s focus is on large data centre and infrastructure projects, where it combines staffing with broader construction site services under one partner. This positioning aims to make it easier for main contractors to organise and scale their site operations on complex projects.

Market

Growing demand for data centre construction services in Finland

Finland is seeing strong activity in data centre construction, with several large projects under way and others announced. Ahertaja is currently involved in major data centre projects in Vihti and Espoo together with established contractors. The company is also preparing to participate in planned projects in locations including Lappeenranta, Forssa and Vaasa together with its existing partners. This concentration of long-term data centre projects creates stable demand for skilled site workforce and related services, which is the core of Ahertaja’s business.

Why data centres are being built in Finland

Several practical and sustainability-related reasons make Finland an attractive place for large data centre investments:

  • Cool climate lowers the energy needed to cool large server halls.
  • Stable, low‑carbon power a reliable grid and good access to low‑carbon electricity help manage costs and support operators’ climate targets.
  • Use of waste heat in Finland it is typical that waste heat from data centres is fed into district heating networks to warm buildings, including for the data centres Ahertaja is involved in building.
  • Commitment to renewable energy Microsoft has stated that it will cover the electricity consumption of its new data centres in Finland with fully renewable power through long-term power purchase agreements (PPAs) with Finnish wind and solar producers, including the data centre projects Ahertaja supports.
  • EU location and regulation predictable rules, strong data protection and an EU jurisdiction are attractive for long‑term projects.
  • Strong digital infrastructure good connectivity and a skilled technical workforce support large‑scale data operations.
  • Long project pipeline for companies like Ahertaja this means a series of complex construction projects that need reliable staffing and site services.

Use of funds

The company intends to use the proceeds mainly to strengthen working capital for ongoing projects in Vihti and Espoo and to prepare for additional projects together with its existing partners. The tables below show how the funds are expected to be used at different total bond sizes.

Scenario I: approx. €250 - 300,000

Smaller bond size focused on supporting working capital needs for ongoing projects in Vihti and Espoo and reducing the most expensive short-term financing.

  • 15% — mobilisation of teams and services when new phases of existing projects start.
  • 15% — reduction of more expensive short-term financing and a small buffer for timing differences between costs and customer payments.

Maximum scenario

Scenario II: approx. €300,250–600,000

Larger bond size that supports working capital for current projects and prepares Ahertaja for additional data centre projects in other locations.

Use of funds

Security

The following collateral is provided for this funding round: a business mortgage in the amount of 100 % of the value of the bond,  and a guarantee as for own debt  in the amount of 25 % of the value of the bond.

Detailed information on the collateral can be found in the KIIS in the documents section for this funding round.
 

Risks summary (simplified)

Investing in growth companies through bonds is very high risk. You can lose part or all of the money you invest.

The following text is a short and strongly simplified overview of selected risks of an investment in Ahertaja Yrityspalvelut Oy Ltd.
It is not complete and does not replace the detailed description of risks in the Key Investment Information Sheet (KIIS).

Before you invest, you must read the KIIS in full and with care and check whether you can understand and bear all of the risks described there.
If there are any differences between this summary and the KIIS, only the KIIS is legally binding.

Key Risk Areas (Short Overview) 

Business, market and management risk 

Ahertaja depends heavily on major data-centre and construction projects and on a small number of large customers. A delay, less work or the loss of a customer could reduce revenue and cash flow. The company must also find enough skilled workers and manage rapid growth. Its management has construction experience but limited experience of scaling a rapidly growing business. 

Sector, project and funding risk 

The construction and data-centre sector can be affected by project schedules, the availability of personnel and wider economic conditions. Rapid growth requires money for wages and other costs before customer invoices are paid. If receivables are delayed or costs rise, the company may face pressure on its cash flow and funding. 

Default, return and liquidity risk 

The company may be unable to pay interest or repay the bonds. This could happen, for example, because of weaker economic conditions, management problems, insufficient cash flow or unsuitable financing. You could lose some or all of your investment. Collateral may be difficult to enforce or may not cover the loss. Returns can be lower, late or absent, and inflation, costs, exchange rates and your tax situation can reduce your return. The bonds cannot normally be terminated early by investors. There is no liquid market for them, so you may need to hold them until maturity or sell at a loss. 

Platform, investor-rights and technology risk 

The platform may be temporarily unavailable or may close. This can delay communication or payments, although your contractual claims against the company remain. As a bondholder, you have no voting or participation rights and cannot influence the company’s decisions. Bond terms may be changed by a required majority of bondholders. The electronic register, digital safe deposit box or related systems may have technical problems or be attacked. You could temporarily or permanently lose access to your bonds. 

A complete and detailed description of all risk factors can be found only in the KIIS in the documents section of this funding round.
