Who we are

About Invera

Invera stands for Investment Ethics Research & Advisory. Ethical and sustainability analyses for investors are our core competence. Our company was founded in 2005, but our dedication to sustainablity stretches back much further.

In 1982, Dr. Elisabeth Höller started an asset management company, specialising in ethical and sustainable investments. At that time, she was the sole player in her field, also in terms of research and data. Twenty-three years later, she set up her company Invera, which was registered in the Zurich commercial register on 1 April 2005, relying on her proven research approach. From that date, Invera has pursued a single objective:

Identification and development of investment solutions that generate an ecological, social and ethical impact alongside a financial return.

As a pioneer in the field of sustainable investing, we have an impressive track record combined with extensive experience. Our research has always focused on ethics and sustainability, which is why we did not need to rethink our strategy and refocus our company when sustainable investing became a major trend. The same holds true for our independent ethics committee: top-class and interdisciplinary, it regularly meets and assesses every investment opportunity that meets our standards, which go beyond the ESG criteria.

We offer a wide range of services to institutional and private investors, who benefit from our know-how, our experience and our network. Moreover, we have set up an ethical investment fund called “Excellent Global Mix”.

The members of our ethics committee work hard, take independent decisions and are invaluable to Invera. During periodic conferences, they define, review and revise our strict exclusion criteria, whereby they set particularly tough standards for critical products and controversial practices that partially go above and beyond the ESG criteria. Each security must satisfy these exclusion criteria for inclusion in our investment universe. Furthermore, our ethics committee screens the underlying stock and bond holdings of our investment fund “Excellent Global Mix” to ensure that these meet our high ethical standards at all times.

The investment ethics research team

Our specialised Investment ethics research team creates our investment universe, applying the exclusion criteria defined by our independent ethics committee to individual stocks and issuers. In order to ensure the highest possible quality, we work together with Inrate, an independent rating agency specialising in sustainability. We follow a multi-person approach. Each security is analysed by at least two team members. Furthermore, we rely on the principle of rotation when assigning the securities to be analysed to prevent subjective ratings based on personal preferences or aversions. All of our analysts have an in-depth knowledge of a natural science or humanities discipline.
