Establishment Simec Engineering

Simec Engineering (Now Yellax Nederland) originated from the grass roots due to dissatisfaction about inefficiently designed industrial controls. As a sole trader, Patrick Vergeer started designing electrical machine controls from his attic on April 1, 2001. Patrick developed the "Typical Manager" software application because people were dissatisfied with repetitive tasks, inflexibility and high error-sensitivity in design processes.


Name change Yellax Engineering B.V.

Simac legally forces Simec Engineering to renounce its 'Simec Engineering' name. At that time, Patrick and Sylvia gave birth to Axell. The name Yellax was formed using the balloons in the maternity room of Jelle, Britt and Axell. "Yel" from Jelle and "Ax" from Axell. For a long time, Britt believed that the B.V. abbreviation actually stood for Britt Vergeer! She knows better in the meantime 😊


Relocation Yellax

The promotion of Typical Manager starts to pay off. It is thus necessary to move to a larger location. Yellax is now located at Edisonweg 1, IJsselstein.


12.5 year anniversary Yellax

Start of BeeFinity development and shareholder participation

"Development on Article Manager (now BeeFinity) started in 2016. This is a web application for efficiently managing and finding electrical products.

Three shareholders also joined this year: Theo Klaassen, Hette Feenstra and Herbert van Donselaar"


Founding of Yellax Belgium bvba

Establishment of the first branch outside the Netherlands, Yellax Belgium located in Hasselt.


Yellax name change

"The name was changed from Yellax Engineering B.V. to Yellax Nederland B.V. in the run-up to foreign activities.

From 2018, the transition from product-oriented to solution-oriented would become clear in the market. We are a knowledge partner that offers tailor-made advice, specialises in technology and focuses on the human aspect to process optimisation and team-building in the engineering teams of our customers. The software applications ""Typical Manager"" and ""BeeFinity"" are thus tools that help our customers to design their industrial controls even more effectively."


New managing director

From January 2020 onwards, Theo Klaassen took over the position of managing director from Patrick Vergeer.

Theo: "I would like to thank Patrick and the whole Yellax team for their trust and this honourable challenge. Together with our remarkable team, we have developed Yellax into a successful organization, of which I am truly proud! Nothing is more valuable than our open culture, accountability, passion and enthusiasm to add value to our customers every day. I will definitely work hard to progress these positive results in the coming years. We are aiming to become a progressive knowledge party that enjoys sharing its knowledge with the market. An organization in which the employee is put on a central spot and which can highly support customers from the Industrial Automation sector in standardization, automation and the process related to that. Essentially, there is a great amount of motivation to continue working with our excellent team and drive our business forward!

Employee story

Working at Yellax means being part of in a very nice team, where employees come first. We do a lot of knowledge sharing and regularly organise get together to socialise with colleagues. This helps to create a close-knit team, which gives me a lot of energy. Because consultants have to visit many different customers, our work is very diverse. And if you also consider the pleasant culture that prevails at Yellax, I really enjoy going to work every day.

Employee story

Working at Yellax gives me the opportunity to look behind the scenes at various companies. It encourages me to use my knowledge to offer added value to every company. At the same time, it allows me to invest in myself by being open to other working methods and different perspectives at different customers. As a person, I fully enjoy this unique blend.

Ronald Stout
Hardware Engineer

Employee story

I work as a software developer on Typical Manager, which is the independent, multidisciplinary engineering platform of Yellax. We use Scrum as a development methodology when expanding and improving our application. A more important aspect of my work involves explaining the architecture of our applications and thus raising quality to a higher level. There is great appreciation if you come up with ideas. It doesn’t matter how young or old you are, your voice is always heard.

Danny de Groot
Software Developer

Employee story

In my role as hardware engineer, I enjoy helping customers with issues encountered in their processes. It is satisfying when you not only see projects running smoothly, but also see your colleagues growing during the process. I get my energy from acting proactively during the process. I am happy to take matters into my own hands and encourage the team to work together to focus on our goal. We end the week with our close-knit Yellax family, which helps to keep our work enjoyable.

Dwight Bruno
Hardware Engineer

Employee story

As a consultant, I help our customers to optimise their engineering processes. This involves contributing to technical solutions and improving business processes that relate to engineering. Communicating and cooperating with customers is an important part of my work. This, and the technology we use, makes my work challenging and fun. Every time, I want to work with customers to find the most suitable solution. When the results of changes become visible, I go to the next challenge with a satisfied feeling.
