Hi, I'm Dennis.

I've been doing online marketing for 9 years — self-taught, which means I learned by doing, not by studying theory. I spent time on the Google Ads Support team in the DACH region, where support agents had access to any account on the platform. That means I've seen inside some of the biggest ad accounts in the world — Nike, global retail brands, major agencies running hundreds of campaigns at once. That gave me a perspective most marketers simply don't have: I saw what the biggest budgets were doing, what they were getting wrong, and what actually moved the needle.

After Google, I spent six years working with major agencies — building the kind of account discipline that only comes from operating at scale. Then I went independent: 150+ clients across Europe, North America, and beyond. Small businesses, moving companies, SaaS startups, local services. The work is always the same at its core: figure out what's broken, fix the tracking, build campaigns that convert, and make it easy for the client to understand what's happening with their money.

I started Growth Junction because the "agency model" is broken for small businesses. You hire an agency, get handed to a junior account manager, receive a report full of vanity metrics, and pay CHF 3,000/month for someone to press pause and resume on campaigns. That's not what I do.

How it works

Growth Junction is built around a simple idea: you work directly with the person doing the work. No junior handling your account, no account manager relaying messages. I use AI tools across every part of what I do — research, copy, reporting, analysis — which means I move faster and stay sharper than a traditional team, at a fraction of the cost.

One dedicated operator, AI-augmented. You get the strategy and judgment of someone who's done this for 9 years — running faster and sharper than a whole agency team, without the overhead.

Growth Junction

No black boxes. No vanity metrics.
No wasted spend. No excuses.

Outside of work

Based near Bern, next to the Aare — the best thing about this part of Switzerland. I work in English, German, Swedish, and Norwegian, so clients across Europe and no two weeks are ever the same.

I used to compete in downhill skateboarding — including at the world championships. These days I've dialled it back: Brazilian Jiu-Jitsu keeps me grounded, and I catch ocean waves whenever I get the chance. I also quit coffee 1.5 years ago, which apparently surprises everyone.
