Most people assume that good decisions require more time and more information. My research over the past decades suggests otherwise.
Good decisions can be made quickly. They save time, reduce costs, and enable organizations to act—even when situations become complex.
This conviction is why I founded Simply Rational – The Decision Institute.
Today, we help organizations make decisions that are bolder, safer, and grounded in science. The need for responsible decision-making is growing, especially as uncertainty and AI reshape how organizations operate.
To continue building on this path, Simply Rational GmbH has opened a funding round.
Until October 2026, we are looking for investors who share our vision and want to help shape the company’s next phase of growth.
The funding will support three priorities:
→ advancing our next stage of development and innovation
→ strengthening our science-based solutions
→ scaling our impact within organizations
We would be pleased to hear from people who share our core belief: good decisions are the foundation of resilient, innovative, and successful organizations—organizations that keep people at the center.
If you believe in this mission and would like to help shape what comes next for Simply Rational, let’s talk.
Our Managing Directors, Susanne Jung and Philipp Leipold, will be happy to provide further details.
