13+ years experience

My name is Hendrik Lennarz and I´m addicted to Growth Hacking for more than 13 years, now. Unfortunately not knowing, that my job title has such a cool name like “Growth Hacker”.

300+ startups / corporates

As Growth Hacking coach we´ve helped so far 300+ European startups and corporates applying our Growth Hacking process V3.0.

Execute or die!

Our 100 Growth Hacking examples & strategies focus 100% on execution. No bullshit-slides and no boring stories. Our Growth Hacking bootcamps, team workshops and keynotes are a balanced mixture between inspiration and focusing on execution. 

Why Growth Hacking will help you grow faster

Continuous execution triggers Growth!

Sorry, the magic formula of popular Startup Growth stories like Airbnb, Booking, Slack or Facebook is not just one single idea that let them grow like crazy overnight.

10 years working as CTO/CPO for Trusted Shops and 2 years now helping startups and corporates as Growth Hacking coach, let me find out, that it´s even more based on 2 important super powers Growth teams have to learn:

1st: The ability to establish a mindset of instant learning to be a hero in finding & prioritizing new ideas that have the most impact on Growth.
That´s what is called the Growth Hacking spirit.

2nd: It´s the ability to stick to a continuous process of planning, executing, measuring & optimizing new ideas in high-speed.
That´s what is called the Growth Hacking process.

„Hendrik helped our team to get a clear view of all dependencies between all relevant Growth topics. Especially the AARRR-Metrics are eye-opening for us, because we can measure user-onboarding campaigns. Most of discussed ideas are take-aways for our operational business, so that we can measure ROI of the Growth Hacking workshop very fast. Thanks for inspiring us.“

In a world where every brand fights for attention, marketers are most likely to keep their best practices to themselves. That’s why I love the concept of GrowthEurope. They enable growth hackers all over the globe to connect and share their best ideas in an empowering environment. Experts and rookies get together in one place, to reach one and the same goal: Become the best at their craft.

“The bootcamp was awesome the thing I liked the most about it was the personalised approach. We were a group of six, which gave plenty of opportunities to discuss our own projects and get valuable feedback from Hendrik and the group members. Special thanks for doing the workshop in English Looking forward to the English version of the book.”
