We had an exceptionally good and helpful Growth Flash with Katharina, and I can only suggest this format to everyone who runs an online business. We were pretty new to this topic (Growth Hacking) but did start already based on own literature research. Katharina was well prepared (looked at our website, checked if we use analytics and how, ...). The session was very practical, we turned right into the discussion of our situation and really had the chance to discuss exactly our position for an hour, no selling meeting. I can definitely recommend the Growth Flash to everyone and use the chance of this great format.
