We build the software
behind the content.

United Sum is a technology company in the Netherlands. We design and build software for the moment content is made, and for everything that has to happen after it: capture, processing, storage and delivery.

Get in touch

A person working on a laptop in a dimly lit living room in the evening.

What we are building
right now.
