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.

More about Growth Hacking mindset!

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.

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.
