Worldstream is entering an exciting phase of growth. As a Dutch data center and IT infrastructure provider with its own data centers, advanced network technology and more than 2,500 customers worldwide, Worldstream plays an important role in the digital infrastructure of businesses across the globe. The market is growing rapidly. Data consumption continues to accelerate, companies are increasingly outsourcing their IT infrastructure, and demand for reliable and scalable solutions is rising. In addition, data and IT infrastructure sovereignty is high on the agenda for many companies. Worldstream has built a strong position in this market and is looking to accelerate its growth significantly in the coming years.

With Freshstream as a shareholder since 2024, these ambitions have gained further momentum. Worldstream is investing in organic growth, further professionalization and potential acquisitions. This creates a dynamic, data-driven environment where performance, scalability and value creation are key. This is where an ambitious and analytical Business Controller comes in – someone who looks beyond the numbers, connects finance with data and uses sharp analysis to drive better decision-making. Thanks to Worldstream’s flat organizational structure.

In this newly created role, you will work closely with Senior Business Controller Olav Bakker and CFO Ernst Wiemans. The Finance team also consists of a Financial Controller and two administrative colleagues. You will work close to Worldstream’s strategy, growth plans and new projects, while also interacting regularly with Freshstream on analyses and business cases.

As Business Controller, you will work on a wide range of commercial and strategic topics. You will analyze margins, cost structures, forecasts and underlying business drivers, translating data into clear and actionable insights. You will also play an important role in CAPEX investments, such as the development and expansion of data centers. By assessing financial impact and expected returns, you will provide valuable input for key investment decisions.
What makes this role particularly interesting is the opportunity to further build and develop Business Control. Worldstream is growing rapidly, increasing the need for better insights into performance, margins and investments. You will translate data into clear management information and help develop dashboards, analyses and forecasting. This allows you to combine Finance, data and technology while directly contributing to Worldstream’s continued growth and professionalization.

At the same time, you will help further develop the Business Control framework. You will build dashboards, management and investment reporting and create greater transparency around business performance. Working with different systems and data sources, you will have the opportunity to use AI to further automate and professionalize analyses and reporting processes.

This role brings together Business Control, data and process optimization, giving you the opportunity to help build the financial infrastructure Worldstream needs for its next phase of growth.

You are an analytically strong and curious finance professional who wants to understand what really drives the numbers and data. You quickly connect the dots, ask sharp questions and enjoy diving into data to uncover new insights.

You spot opportunities to make analyses, reporting and processes smarter and take the initiative to drive improvements. With your combination of financial expertise, affinity with data and curiosity for technology, you are excited to help build a Finance organization that is becoming increasingly smart, automated and data-driven.

“This role is ideal for an ambitious finance professional who wants to work closer to the business and make a visible impact. You are analytically strong, curious about what drives the numbers and eager to contribute to growth and strategic decision-making. At the same time, you are energised by data, automation and AI, and you see opportunities to make Finance smarter and more effective. A great next step for someone who wants to build, challenge and innovate.”

Worldstream is building the digital infrastructure that powers businesses worldwide. From its own data centers in the Netherlands, the company’s team of more than 100 professionals provides powerful and scalable cloud and IT infrastructure to over 2,500 customers. From dedicated servers and cloud solutions to storage, colocation and connectivity, Worldstream largely owns and operates its technology and infrastructure. With more than 15,000 active servers, the company provides a critical digital foundation for customers across sectors including technology, e-commerce, logistics, financial services and media.

Worldstream operates in a rapidly growing market. Data consumption continues to increase, IT environments are becoming more complex and more organisations are choosing to outsource their IT infrastructure. At the same time, speed, security and European data sovereignty are becoming increasingly important. Worldstream has built a strong commercial position in this landscape by combining high-quality technology with personal service, specialist expertise and 24/7 support. The business is commercially successful and, from this strong foundation, is actively looking to expand its customer base, services and geographic reach.

Since 2024, Freshstream has been on board as a private equity investor, working alongside management to shape Worldstream’s next phase of growth. The executive team, consisting of CEO Ruben van der Zwan, CFO Ernst Wiemans, CCO Rogier Heijligers and COO Nick de Jong, is building on the company’s strong commercial foundation. The ambition is to accelerate organic growth, enter new markets and further professionalise the organisation. At the same time, Worldstream is actively exploring acquisitions that can strengthen its service offering, scale and position in the European market. The ambition is clear: to build a larger, scalable and commercially strong player in the European cloud infrastructure market.

This ambition goes hand in hand with an entrepreneurial, informal and close-knit culture. Colleagues genuinely describe Worldstream as a family: communication is direct, people know each other well and there is a strong sense of working hard and having fun together. The team regularly organises social activities, while the office environment places a strong emphasis on connection, wellbeing and enjoying the journey together.
