Performance is the result of a disciplined process. Our expertise is to define and implement a governance and an investment policy that suits you, as well as to control the results. Through our disciplined and ethical approach, you capture long-term trends, integrating your specific needs and your clients' expectations.


The global trend is toward transparency and benchmarking. Changing the quality of your processes and management reporting will help you be more efficient and achieve better results.


With the entry into force of the LSFin, asset managers and financial advisers will now have to formalize and document their investment policy, and then properly apply it in the portfolios they manage.


A small private bank, an independent manager or a family office do not always have in their teams someone who can take on the role of Investment Manager (CIO). But recruiting an experienced internal CIO takes time and is rarely economically justified.


By outsourcing this function, you not only ensure a rapid compliance with the new requirements, but also benefit from the skills of an experienced specialist at a low cost.



Whether you are an independent manager, a family office, a private bank or a pension fund, we support you at every stage of your management process, with a complete range of tailored analysis and investment services to meet the needs of professionals.


The basis for efficient management delivering superior results is well-managed governance and internal organization. Premyss helps you establish a documented governance, adapted to the size of your structure and its DNA, in order to express your values ​​while meeting the regulatory requirements. In addition, it will enable you to obtain better quality performances, guarantee appropriate communication internally and externally, promote transparency and thus offer a better service to your customers.
