Thriving in today’s overstimulated world has never been harder.
We treat ourselves like machines, constantly “on,” multitasking, and never truly unplugging. Yet, this is making us less effective and more exhausted.
However, the secret to achieving more and stressing less isn’t about doing more, but about optimizing three things: focus, sleep, and stress.

The Ultraproductive 90-minute method is a simple, science-backed approach that addresses three key aspects of productivity and well-being:
Dedicate just 90 minutes a day to deep, uninterrupted work and watch your productivity double—without working more.
Prioritize 90 minutes of deep and REM sleep nightly to supercharge your brain and increase output by up to 2.5 times—without sleeping longer.
Break stress cycles every 90 minutes to maintain energy and sustainably double your effectiveness—without burning out.
We don’t just inspire your people to change. We show them why the methods work and, more importantly, how to put them into practice during a busy workday. Keynotes and seminars are available in person or remotely, in English and German.
In our keynotes, we introduce the foundations of optimizing focus, sleep, and stress.
Our keynotes run for 60 to 90 minutes and include a Q&A session as well as practical handouts, enabling participants to apply the ideas immediately.
In our seminars, we go deep into the science and practice of optimizing focus, sleep, and stress.
Our seminars combine in-depth Q&A sessions with comprehensive workbooks, helping participants build lasting habits for more focus, better sleep, and less stress.
