Thomas Harnisch
I combine 20+ years of performance marketing with artificial intelligence: AI applications, automated processes and data-driven media buying.

About me
I turned my hobby into my profession.
Since 2004 I have been working on online shops, websites and the digitalisation and automation of offline processes. My core competencies include digital media buying and its optimisation through self-developed automation processes.
Today, artificial intelligence is at the centre of my work: I build AI applications and websites, automate processes and work with data using AI — implemented independently or as project lead together with external agencies.

AI & Automation
For me, AI is not a buzzword but a tool: I use it to build applications, automate marketing processes and make data usable.
AI applications
Building my own AI applications and websites — from idea to prototype to productive use in day-to-day marketing.
Automated processes
Digitalising and automating offline and marketing processes, up to a fully automated marketing value chain.
Data & AI analysis
AI-supported work with data: analyses, customer score cards and first-party data management as the basis for better media buying.
Many of these AI projects were realised at DSR Hotel Holding — some independently, some as project lead with external agencies.
