Created with love

Working daily to deliver a user-friendly and efficient software solution to users all over the world.

In 2015, Adversus started as a bold idea in a garage. Tired of outdated and clunky telemarketing tools, our founders Mads and Kristian set out to build something better. Something that actually worked for the people using it.

So they did. A platform designed to streamline calls, reduce busywork, and help sales teams focus on what matters.

Today, we’re a global team based in Aarhus, Denmark. We support clients in more than 25 countries and power over 1 million calls every single day. 

But Adversus isn’t just about call volume or clever features. It’s about helping businesses grow faster, work smarter, and waste less time. Whether you're running a B2C call center or booking B2B meetings, our platform fits your flow. 

With a user-friendly interface, unmatched uptime, and exceptional support, we are committed to delivering excellence.

Why Adversus?
Because we don’t just help teams make calls. We help them make an impact.
