About

Miner of mobile growth gems  at GrowthGems.co / Mobile growth at Babbel. Passionate about growth and mobile growth. I'm especially into optimizing onboarding and the early user experience to improve monetization and revenue. I also work on user acquisition and app store optimization. I do not provide consulting services (I have a full time job) but happy to exchange ideas and advise on a call here.

Expertise

general

Inbound Marketing Strategy / Content Marketing

I can help you with your Inbound Marketing Strategy. I love to chat about cornerstone/pillar pages, content marketing funnel and conversion optimization. And of course tracking all of this the right way in Google Analytics. I did this for the agency I co-founded (Apptamin) and helped others as well.

App Store Marketing

I've been involved in app store marketing since 2009. I can help with your overall marketing strategy as well as App Store Optimization (ASO) in particular.

Product Growth & Monetization

My main area of expertise (what I focus on the most at Babbel - and what I like thinking about the most) is optimizing onboarding and the early experience to increase revenue.

Sylvain had great advice - saved me from expending a lot of time and effort on something that is pointless given our companies current situation.
