Let's talk

Why work with one senior marketer instead of an agency?

Ten years working across marketing: small businesses, scale-ups, large organisations, and everything in between. As a freelancer, I've worked as Head of Marketing at Spotto and as Digital Project Manager at Focus Advertising. I've built strategies, coached teams, and worked from a laptop in Lisbon, and from a beach in Bali, more than once.

I started Just Jane because I wanted to work with more than one company at a time, on my own terms, without growing into an agency. The work stays personal: you work with me directly.

Senior expertise. Personal approach. No agency markup.

Alongside Just Jane, I'm also the founder of BAJA Academy and Mayday.

How does Jantien Vanderbeke work?

  1. 01Personal.You work with me directly. No pool of coaches, no junior filling in a plan someone else sketched.
  2. 02Strategy that gets executed.Every engagement is built to be used and run, from the first week.
  3. 03AI underneath, marketing on top.AI makes the work faster and broader. The work itself is marketing. Always.
  4. 04I teach, you own.What we build stays yours: your accounts, your workflows, your documentation.
  5. 05Direct and practical.I coach the way I'd want to be coached. We get to the point.
