Europe’s Top Growth Hackers – Your complete guide to Growth Hacking

How often have I answered the question “Hendrik, how have you heard about Growth Hacking the first time“? No idea.

Just a few days ago, I answered the question 3 times, while standing at the coffee machine on a Growth Hacking coaching day for a corporate accelerator program in Düsseldorf.

Unfortunately, the answer is a bit boring. You can read it in my book – but that’s probably not why you’re here.

Instead, I’ll give you a full-blown head start – so that you can understand what Growth Hacking actually is, and get introduced to some of Europe’s Top Growth Hackers.

What the F**k is Growth Hacking?

„A Growth Hacker is a person whose true North is Growth“ – Sean Ellis.

I am pretty sure that you will immediately think about that colleague whom you have often wondered what he or she is doing in this moment or has achieved the last week.

You might even think of several colleagues immediately, right? Too many people and tasks around, you have no clue if it is worth it to have them in the team?

Okay, next example.

Is there a task that you have done or might have done in the last 2 months, you may have been wondering all the time what impact that might have on your company’s Growth?

By the way, these questions are not only common in big companies and corporations with hundreds or thousands of employees.

The same goes for the majority of startups. Here, for example, hundreds of e-mails are sent out without measuring how many users they really reached or knowing how much revenue was generated from them. Maybe they should have invested this time in something completely different? Who knows…

Of course, you can also apply that to your household. If my wife, just before I start cooking, scrubs the stove clean, that does not make much sense, in my opinion. But well, that’s another story. Better to stop here 😉

Means, the big challenge for startup founders or executives in large companies is to steer everything – really everything – in the right direction, in the direction of growth.

And that’s exactly what Growth Hacking is all about.

Let’s take a closer look at the two terms:


Means growing something, or increasing the value of something. In terms of business models or startups, the steady growth of the number of users, as well as the turnover or the profit margin is meant. Nothing new so far, right?


To hack into a system means penetrating into a system. At first glance, nothing incredible, right? But in combination with Growth?

It is important to understand that a Growth Hacker always follows a specific goal.

In order to achieve this goal he has to try countless ideas, methods and helpful tools on countless target objects. A Growth hacker does not have to stick to given processes or rules.

Rather, he also has to regularly think very creatively to achieve his goal. Experience, know-how, endurance and creativity are essential skills there. A Growth Hacker is a master in Trial and Error.

Let’s get it all together and finally come to my very own definition of growth hacking:

Growth hacking is a constant optimization process. It is about the perfect synchronization of the team-roadmap to achieve the overall Growth goal. The 4 disciplines of product development, business model, creative marketing and execution speed are taken into account. Unfortunately, there is never a single growth hack that shoots a startup or corporate overnight into the unicorn sky.

I have summed up that process within our Growth Hacking Process V3.0.

Growth Hacking is a process

Passion never fails

Even these basics get constantly challenged. This could also be due to the fact that Growth hacking itself has no “traction” in Germany.

Why do I know that? Quite simply, because in 2017 I was allowed to coach around 900 participants in Growth Hacking.

Of all attendees, about 30% had never heard of the term “growth hacking” before. 

Approximately 50% already knew it and said something like “creative and free online marketing hacks from the startup world”.

The remaining approx. 20% knew that the disciplines “tracking, automation and the right user targeting” are also very important for a successful Growth Hacking environment.

So far so good…

Looking back, my initial Growth idea for my personal brand was to organize a Growth Hacking Bootcamp every month in another German city. In total, we have successfully completed 31 bootcamps in the cities of Cologne, Düsseldorf, Frankfurt, Munich, Berlin, Hamburg, Amsterdam, Vienna, Zurich, Bonn and Stuttgart in the last 24 months. These bootcamps are not a great cash cow, but a very useful method to spread the Growth Hacking idea around Europe. Moreover, a useful tool to heat up the Growth Hacking Spirit to as many willing Growth Hackers as possible.

But very exhausting to do this alone, honestly.

Behind the scenes story

When I set my business goals for 2018 a few weeks ago and stuck the Post-It on the wall saying „Growth Hacking Speaking Gig in US,“ I noticed pretty quickly:

  1. I can not do it alone. I need a community of Growth hackers to get „traction“ on our favorite topic in Europe, finally.
  2. A community of Growth Hackers in Germany alone will not be big and strong enough to be interesting for the US. That must be at least Europe.

So this year I plan my bootcamps also internationally. No problem. The 1st Growth Hacking Bootcamp in Vienna in January was sold out completely and therefore a huge success. So happy! In addition to the major German cities in 2018 Zurich, Amsterdam, Paris and yet another international bootcamp will be added. In parallel, I will have my book translated into English…So far my idea list.

Pretty much Gary Vaynerchuk Hustle, right?

But, do you know what? I got it very quickly by my self, no worries… 😉 This challenge will probably not be enough. We need something cool, big and scalable, my growth hacker mind told me…

Europe, here we come!

And then I got it! To be honest, I was inspired by my personal growth hacker champion Neil Patel. He regularly hosts online summits in the US, with himself or with top speakers who simply stream their sessions from their office, across the web, into the world. And attendees can just as easily attend from home or office.

That’s cool. That’s innovative. That’s scalable. That fits perfectly with the Growth Hacker Image, right?

This is the chance to be able to spread the Growth Hacking Spirit across Europe, right? And best of all, nobody will complain about the non-tasty food you get on conferences 😉

The Growth Europe Summit – Featuring Europe’s top Growth Hackers

So in 2018, we organized the Growth Europe conference. The goal? Spreading the growth hacking spirit, learning from each other, and be inspired.
