Scaling brands with the mindset of an athlete.
Business isn't a gamble. It's discipline, clarity, and execution. That's how I help eCommerce brands break records.
About Dennis (The Story)
In 2019, at a dining table stacked on books in a small dodgy apartment in Rotterdam-South, Dennis made a decision that changed everything. At the time, his life looked like most others: a full-time 9–5 job, the perspective of working for a boss until retirement, and a humble background without any entrepreneurial blood. With no money, no network, and no safety net, nobody expected him to build what he has today.
The alarm went off every morning at 4:30 AM. Discipline came first: training, clean eating, reading, and hours of work on his business before the world woke up. At nine sharp, his job began. When the bell rang at five and most people called it a day, Dennis was only halfway. He worked late into the night, seven days a week, and in over six years only missed three days when he was too sick to get out of bed. His first “yes” came after weeks of cold calls and door knocking — a local carwash. With no budget, he did everything himself, from creating the ads to reporting on results. That was his first rep. And reps build strength.
If your goals touch business, marketing, or advertising, you’re in the right place. Not for shortcuts. Not for hype. For clarity, discipline, and results.
Make it stand out.

Advantage Program
I built Advantage to give brand owners, media buyers, and agencies the shortcut we never had. It’s the proven system behind $150M+ in sales, distilled into a program you can apply right away. Inside, you’ll find the ad strategies, creative frameworks, SOPs, templates, and community that help you stop guessing and start scaling. It’s the playbook for anyone serious about turning 5–6 figure months into 7+.

We don't talk about potential — we put results on the scoreboard. Since 2019, our team at DDU has helped 200+ Shopify brands scale profitably through performance marketing and creative systems that deliver. From fashion to food to supplements, the industries vary — but the outcome is the same: disciplined growth and record-breaking performance.

The Athlete Playbook
Scaling isn't luck. It's not about chasing hacks, random trends, or copying what others do. Scaling is discipline. Structure. Reps.
That's what I call the Athlete Playbook — the principles I've used to grow from a dining table in Rotterdam to managing over $50M+ in ad spend and generating $150M+ for eCommerce brands worldwide.
This hub is where I share those lessons. The real ones. Not recycled blog posts, not "guru" theories. Just unfiltered insights from scaling 7, 8, and 9-figure brands with a team of A-players.
You’ll find:
Battle-tested growth frameworks you can apply immediately.
Creative systems that turn ads into machines.
Mindset shifts that separate winners from everyone else.
Proof Over Promises
The Movement
DDU was built from nothing — no funding, no backing, no safety net. Just discipline, belief, and relentless execution. That same DNA drives where we’re going next.
Our mission is clear: to be the go-to growth partner for eCommerce brands worldwide. Not just another agency on the list — the name you think of when scaling is serious, when performance has to count, when breaking records is the only option.
Let’s Talk
If you’re building something worth scaling, let’s connect. Whether it’s working with DDU, booking me to speak, or enrolling in Advantage, every conversation starts with clarity.
