Maximilian in wenigen Worten

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 fußball.de, 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.
