Bastiaan Korte

Growth Marketer

Bastiaan quickly grasped the potential in our account. In a two-day kick-off, he laid the foundation for a flawless execution. The swift deployment of the PMAX campaigns, ready for Winter '25/'26, delivered impressive numbers right out of the gate. We are particularly pleased with the substantial Black Friday increase, a clear indicator of a well-executed strategy.

FAQ

What is the difference between growth marketing and traditional digital marketing?

Traditional marketing often focuses heavily on top-of-funnel brand awareness. Growth marketing is a highly data-driven approach that runs rapid experiments across your entire funnel, from initial acquisition and activation all the way to user retention and referral, to scale revenue sustainably. You may see similar roles also named as “Growth Hacker”, “Go To Market Specialist (GTM)”.

Do you handle the hands-on execution, or do you just provide the strategy?

Both! I map out the high-level, funnel-based strategy and then roll up my sleeves to build the campaigns, optimize the landing pages, and execute the experiments to make that strategy a reality.

What happens if a project requires graphic design, copywriting, or heavy web development?

I handle all the core growth setups, analytics tracking, and performance-driven copy. For intensive brand design or complex backend coding, I seamlessly collaborate with your internal team or can recommend trusted specialist partners to step in.

How do you measure success, and what specific KPIs will we track?

Success is always tied to revenue-driving actions. Depending on the funnel stage we are optimizing, we will track hard metrics like Cost Per Acquisition (CPA), Marketing Qualified Leads (MQLs), trial-to-paid conversion rates, and churn reduction.

How long does it typically take to see measurable growth in our funnels?

Quick wins, like optimizing an existing landing page or ad campaign, can show positive momentum within weeks. For foundational builds, like launching a brand new outbound engine, it typically takes 60 to 90 days to gather the data, iterate, and start seeing scalable results.

Do you guarantee specific results, lead volumes, or conversion rates?

No professional marketer can guarantee exact numerical outcomes due to constant market variables. What I absolutely guarantee is a rigorous, data-backed testing process designed to systematically uncover the most profitable growth levers for your product.

How do you integrate with our existing internal team or other freelancers?

I operate as an embedded growth partner rather than a siloed vendor. I will plug right into your Slack workspace, align with your product sprint cycles, and collaborate openly with your sales and leadership teams.
