How we got started
We are a group of experienced investment professionals with a shared vision, a passion for investing, a deep understanding of the industry and proven expertise in applying sophisticated data analysis to investment problems. In 2019 we decided to combine our expertise to forge a path toward redefining how advisory services are delivered to professional investors.
Our mission was clear: provide investment solutions that deliver superior performance while providing the thought leadership and the transparency necessary to align their various stakeholders.
With the help of a handful of sophisticated investors, Resonanz Capital was born. As a new company with limited resources, we had to innovate to deliver, leading us to commit to providing technology-based solutions early on.
Today, besides personalized advice, we offer a cutting-edge web-based application (Ensemble) for investment planning, analysis and personalised portfolio management to help our clients take a tailored approach to meet their investment goals.

Our mission
What our names mean
About the name “Resonanz Capital”
Resonanz is the German for „resonance” which means having a deep tone or lasting effect.
In physics, „resonance” refers to the reinforcement and prolongation of a sound by reflection from a surface or by the synchronous vibration of a neighbouring object.
The use of the German version of „resonance“ symbolizes our local roots, here in Frankfurt. It is a term which also has a technical meaning, thus highlighting our commitment to technology.
The idea of a „reverberating“ sound, symbolizes the constant feedback loop with our clients, and our commitment to delivering customized solutions.
The idea of „reinforcement“ symbolises our commitment to meaningfully and positively impact our client's portfolios, often through small changes that then lead to big results.
The term „Capital“ refers to us being an investment firm
About the name “Ensemble”
„Ensemble“ is a French word meaning „together“.
In machine learning „Ensemble learning“ is a technique that enhances accuracy and resilience in forecasting by merging predictions from multiple models.
In music, an „ensemble“ is a small group of musicians that play music together.
Our technology platform, Ensemble, brings together our various expertise or services and organizes them together in order to deliver one good investment solution. This is also why we like to refer to it as our „operating system“ for hedge fund investing.
