Built by outbound people. For outbound people

Outbound software that works the way outbound teams actually work. 

In 2015, our founders Mads and Kristian started Adversus after years in outbound. 

They were tired of tools that slowed teams down instead of helping them sell. So they built a platform designed around real outbound workflows and daily operations.

What started in Kristians mom's garage became a calling platform designed to remove busywork, streamline workflows, and let sales teams focus on conversations that drive revenue.

That mindset still defines how we build today.

Adversus is not only built for outbound teams. It is used by our own team, every single day. From sales to customer success, we run on the platform ourselves. That means we experience the workflows, the edge cases, and the small friction points firsthand. 

We help businesses grow faster, work smarter, and eliminate unnecessary complexity. Whether you operate a B2C call center or book B2B meetings, the platform adapts to your process rather than forcing you into ours.

With a user-friendly interface, industry-leading uptime, and dedicated support, we deliver a platform teams can rely on.

Today, Adversus is headquartered in Aarhus, Denmark, and supports clients in more than 25 countries.
