Andreas Ehstand
Understand how you think — and you understand how you play.
Supported by performance factor analysis in sport through artificial intelligence
Sport scientist and AI Scientist in one: founder of the AUGMANITAI research practice, studying how people and organizations think, learn and work with artificial intelligence.
The outcome of a session: 3 to 5 named, measurable factors of a player's game and a training plan built around them.
Every credential on this page is named and dated at its issuing organisation — documented, not asserted.
Andreas Ehstand combines over 15 years of international high-performance sport expertise with empirical-methodological training.
Career stations include the Institute for School Development Research (IFS) at TU Dortmund (research associate) and the University of Bayreuth.
Coaching experience
Over 15 years of international experience in high-performance coaching, in tennis, padel and pickleball. Bundesliga and ITF coach. Stations include the USA, Austria, Qatar and Dubai as well as, nationally, Bavaria, Hamburg, North Rhine-Westphalia, Schleswig-Holstein and Baden-Württemberg.
Methodological focus
Performance factor analysis — the systematic breakdown of complex performance into nameable, measurable components.
Applied in individual and group training, in association and club work and in individual career planning.
Behind this lies the same core idea as in Andreas Ehstand's AUGMANITAI research: a state you can clearly name becomes a state you can steer. On court, that means breaking technique and tactics into single, nameable factors instead of training on vague gut feeling. A nameable factor can be as concrete as the grip angle on the forehand, the timing of the split step, or the decision time on a return.
Performance factor analysis for tennis, padel, pickleball and golf.
Academic background
Sport-scientific and empirical-methodological training at the University of Bayreuth and at TU Dortmund (Institute for School Development Research, research associate (2012–2013)). Teaching experience at universities in sport pedagogy, general pedagogy, didactics and performance factor analysis.
This academic training at two universities is the basis for the performance factor analysis: training decisions are not based on gut feeling, but planned using empirical-methodological training. In practice that means: video analysis and measured values, not pure feeling, decide what is trained next.

Documented credentials — the hard facts
Two things are documented here, each in its own register: the coaching qualifications below are training stations named by their issuing organisations (Rafa Nadal Academy, GPTCA, DTB) — and the name "License of Clarity" is legally protected as a registered EU trademark (EUIPO, since May 2025).
To be precise: ORCID is a scientific identifier for the research and publication record of Andreas Ehstand — it documents research identity, not coaching licenses. The coaching qualifications below are documented by their own issuing organisations, not via ORCID. The registered EU trademark "License of Clarity" (EUIPO, since May 2025) protects the name legally — it says nothing about coaching skill.
