About Zalster

Senior specialists for marketing challenges that cross disciplines.

Why we exist

Marketing becomes less effective when each specialist only sees their own numbers.

Zalster brings the disciplines into one conversation. That means channel decisions can account for measurement quality, technology constraints, creative learning, and the economics of the business.

Since 2015, the brief has expanded from managing campaigns to connecting the systems around them. That history helps us recognise the difference between a new opportunity, a repackaged platform feature, and a problem that needs fixing at the foundation.

Independent Gothenburg agency · Since 2015

More than ten years of change has made us less interested in shortcuts.

Zalster was founded in 2015. The tools have changed quickly since then, while the need for clear priorities, dependable measurement, and well-executed work has remained.

01

Platforms will change

We have seen channels, formats, and algorithms come and go. The strategy still needs to work after the next product update.

02

The business is the reference point

Platform data is useful, but margin, customer quality, and realised sales decide whether the work creates value.

03

Experience should stay close to delivery

Senior specialists remain involved in analysis, implementation, and ongoing decisions—not only the first meeting.
