Konstantin Johannes Safiriou

We remember Konstantin J. Safiriou (1949 – 2020).
He was our friend and inspiration. 

Konstantin Johannes Safiriou (* 1949), private scholar, author, economic and cultural advisor, died too early, predictably and yet unexpectedly on September 14, 2020. He was a boisterous free spirit, someone who could critically question everything and investigate things underground. Not everyone was familiar with his way of thinking, but those who sought his help and advice appreciated it with honorable respect.
At the beginning of his career he was a journalist for various sports magazines, later on he was a chief reporter of a  well-known daily newspaper. He founded a weekly newspaper – but economic pressures from established competitors forced him to give up. He boosted the public appearance of key trade fairs at KölnMesse (like Photokina, Anuga, Herrenmodemesse) in a consistently inspiring way for a couple of years. In encounters and advising politicians and economic leaders, he found an interesting task while being on friendly terms. He created sustainable concepts for global companies, and in the German food and c+c trade sector he was an innovative marketing consultant for years.
He started numerous companies of his own to develop absolutely new things (e.g. in the tourism, industrial and IT sectors). He was not a hard businessman by the way, he was interested in scientific context. In the field of history, sociology, and economics he became a notable old-style private scholar, who wanted not to make a profit from everything. 

Last but not least his private interests challenged him over and over again to promote art and cultural projects. He made no fuss about it. Unselfishly he had supported the work of art mediators and avant-garde artists for decades. He was a significant art collector with a fine taste and donated his artworks mostly for charitable and public purposes.  As co-editor he was involved in various publications, i.a. about philosophy of photography. 

At ArtExpert I Network, an international platform for art-scientific and material-technical research, he was responsible as a long-term management advisor. Additionally, he has also been a honorary board member of Artforum Culture Foundation since its inception.

Konstantin Johannes Safiriou – rest in peace.

ArtExpert is entitled in this case to discontinue the services and to pay compensation amounting to at least 35% of the agreed fee or the fee to be charged according to HOAI as compensation for the loss. For further provision of services, comprehensive instalment payments must be guaranteed. Payments are due and payable at the time of invoicing.

Art Management

Art Management

Visual arts, also interdisciplinary extended to music, theatre, film, literature and new media move in the tension field of personal experience. The civilatory sphere in which societies live is determined any time by its cultural value. Besides, prominent personalities, cities and corporates have tried to define themselves always about their cultural engagement. The claim of a community or a company appears outwardly, but also towards the own members / employees about their economic, social and cultural engagement. To transfer innovation, growth and success ist he duty of central marketing, advertisement and public relations, but this can be easier and clearer formed and explained by inclusion of art and cultural management.

Companies and public facilities may use for atmospheric representation and for the personal identification of the employees and customers of their buildings pictures and sculptures. We have to imagine, that discussion about art and culture has not only to do with decoration but with constant integration of innovative processes. In this sense, art and culture will promote the competition of companies and municipalities. This will lead consequently to strengthening of the company and the whole economic area.

But Art Management is at first within the tasks of any artist. As a free-lancer she/he has to know the rules of economy and marketing. We have to imagine, every professional artist is an entrepreneur and an inventor.

Collectors, public projects as well as the artists themselves need some instruments to optimize their approach.
Without exhibitions, catalogues, monographs and poster the public cannot be involved.

With ArtExpert I Network we can support and advise  you to become part of the national and global art world.  To work systematically will help to prepare a catalogues, monographs, which are necessary media in contact with art collectors, gallerists and museums. Last but not least a catalogue raisonné will be an important instrument to inform the public and to built up trust.
