Maximilian in a few words

I am an app-marketing-native. As a specialist in App Store optimization, I have self-started MyFitFeed a fitness nutrition app (which me and my team grew from zero to 200.000 downloads without any marketing spending).
I have also worked for Asana Rebel, Arise, Pantaflix, Spotify, Kaufda and fuß, among others.

When I am working with marketing teams I am conveying the principles for app- and search-engine-optimization, App Marketing and Growth Hacking.

My current field of focus is Sustainability and Climate Change.
Where I am supporting this movement as good as I can with my expertise.
Imagine the mindset of a Cambridge Analytica applied to the emerging businesses in sustainability.

So if you need someone to coach your team to find the right marketing strategy who has a holistic mindset, a proven record in growth hacking digital products and who is able to implement rapidly, we should talk.

Growth Hacking Workshop

Growth Hacking workshop to apply the principles of Growth Hacking to Sustainability Consultancy ( BCorp certified)

The sustainability movement needs holistic marketing practices.
Inspiration: Cambridge Analytica uses Marketing as a form of manipulating people to choose badly (Trump, Brexit). Why not use these principles to energize the sustainability movement?!
