Marc Preusche


Managing Director


Dept Data & Intelligence


Marc is the founder and managing director of LeROI, a tech consulting agency focussed on data and its usage, especially in a marketing context: analytics, business intelligence/marketing intelligence, data science. LeROI helps startups and corporates use their data properly in understanding their customers and creating better customer experiences. Our credo is: Instinct is inspiration. Data is proof.

A few examples: data strategy, custom data engineering, better and more automated reporting, actual self-service analytics, multi-touch attribution, customer journey tracking, TV tracking, customer segmentation, predictive CLV, automation, and of course personalization (and many more).

Before founding LeROI, he spent five years at Google in Hamburg and Berlin supporting startups and VCs with AdWords and Analytics. Afterwards, he was one of the first angel investors in Knip (insurance startup) and its first CMO (interim), overseeing marketing, analytics and business intelligence.

Passionate about data and creativity, he is very much looking forward to meeting as many of you as possible!
