Our roots

In 1981 a group of PhD students discovered that by applying innovative modeling techniques they could support companies in making better decisions and therefore improving their efficiency and quality. And that is still our mission today: 

We enable people to manage the complexity of investment decision making.

Because we passionately believe that everybody benefits from better decisions.

Our vision

Models combined with technology provide easy access to complex knowledge, based on vast amounts of data and experiences. Models based on profound market knowledge and used in a proper way contribute to consistency, transparency, and efficiency. These models can thereby help you to become more successful in achieving your objectives.

Our mission statement

It is our mission to enable people - from the professional at a large institutional investor to the private investor saving for personal goals - to manage the complexity of investment decision making. We do this by delivering leading technologies and solutions based on the latest scientific insights.

Models at our core

We design, build, and deliver high-quality software models for asset-liability management, risk management, (impact investment) portfolio construction, performance measurement & attribution, and financial planning. Using the latest technology, data, and market knowledge and in collaboration with our global clients, we continuously find new ways to face the growing complexity of investment decision making.

Impact on society

Our main driver is to enable as many people as possible to make their own investment decisions and improve their ability to reach their financial, environmental, or e.g., social objectives in a balanced way. In addition we provide insights and technology to society as a whole and integrate sustainability into decision making by our clients.

We are committed to achieve carbon neutrality by 2030 by means of minimizing our CO2 emissions substantially and by offsetting any residual emissions. Throughout this journey, we are receiving support from Nexio Projects, a specialized company.
