Our story

Nucleus was established in 2000. Meanwhile, we’ve developed into one of the biggest players in the Belgian hosting landscape. Thanks to expertise, sensible policies and a healthy growth.

Our expertise is our most vital driver. It comes from a growing team of driven people – serious geeks and each and everyone a specialist in their field of business. Together, they form a multifunctional team that strives to the best possible uptime for your websites, applications and servers. We feel engaged and want to contribute directly to the success of our customers.

Nucleus was acquired by Combell in 2019. Thanks to this acquisition, Combell further strengthens its position as Belgian leader in the hosting market.

We strongly believe in the power of partnerships. A lot of our customers are partners too and enjoy some interesting benefits.
