SFO invests in entrepreneurs who see the values of the honorable businessman as their guiding principle. Our own values in detail:


We only invest in entrepreneurs, not self-promoters or dogmatists. We believe that real entrepreneurs give a lot to our society and we want to support them in this.

Sustainability and social responsibility (ESG)

We only invest in topics that promote or consider ESG criteria. At the very least, we do not want to harm the world with our investments, ideally we make it a little better.


With SFO, we have created an excellent alternative to other equity investors. In the same way, we expect the companies in which we invest to develop excellent solutions and excellent implementation of their plans.


We provide real value to our investments beyond equity. We reject investments where we do not add value. Only sustainable interest alignment creates a lasting partnership.


We are ready to support unconventionally even in difficult situations. Be it through the right contacts, a clarifying conversation or a short-term loan to secure liquidity.
