From Soldier-dream to Seven-Figure Squeegee:

“I didn’t know exactly what I wanted to do — I just knew I wasn’t going to take a long education. I’ve never liked school; sitting still and reading was never for me. Then I came across the window cleaning school.

A Restless Beginning

Fresh out of Denmark’s Armed Forces and a stint at folk high school, Frederik had energy to burn but no clear roadmap. He loved moving, hated sitting still, and the thought of running a company—complete with bookkeeping and business plans—felt overwhelming.

Scrolling Into a New Future

Late one night he saw an ad for Vinduespudseskolen (the Window Cleaner School). At first it sounded too good to be true: hands-on window cleaning training, a proven strategy, and a step-by-step guide on how to start a window cleaning business. Skeptical but curious, he signed up.

One Year, One Million

Fast-forward twelve months. Thanks to a subscription-based model taught at the school, Frederik’s company now posts over 1 million DKK in annual revenue. He skipped the beginner mistakes by following the school’s data-driven playbook—not spreadsheets he designed himself.

“If I hadn’t joined Vinduespudseskolen,” he says,
“I would never have hit a million in turnover after just one year.”

From Laughter to Respect

Seasoned window cleaners joked about “the military guy with a squeegee.” Today those same veterans ask him for advice. His subscriber base keeps growing organically, and he admits it “almost feels too easy” because the strategy is already battle-tested—he just executes.

Why It Works for Frederik

Low entry barrier: no fancy gear, no office rent—perfect for someone who hates spreadsheets because companypalnner.com have it all in one.
Subscription revenue: monthly plans smooth out cash flow and simplify forecasting.
Action over theory: instead of calculating every scenario, he follows a blueprint that already delivers results.

Family Reactions

Frederik’s mother still laughs at the pivot from aspiring special-forces soldier to window-cleaning entrepreneur, but even she can’t ignore the results.

Do I need to be physically present in Denmark?

No. Once you become a partner, you’ll be invited to Denmark for in-person training — but that comes later, when your business is up and running and your company can cover travel and accommodation costs. To begin with, everything can be done remotely from your home and then things look different when you have success and are fully flexible as well.
