Who we are
The Artentika Story
Our art research project started in 2008, when we realized that there was an urgent need to develop tools to help protect the art world from pervasive fraud. Artentika (Pty) Limited was incorporated in South Africa in 2017 and invented a groundbreaking art authentication solution patented in the United States in 2022. Uniquely, it is multi-modal and combines several cutting-edge technologies in the field of image and materials analysis with data-driven approaches. Artificial Intelligence also plays a role, but AI is not a silver bullet and cannot be relied upon in isolation. In effect, the true value of science for the realm of art lies in complementing, not replacing, the expertise of art historians, conservators, and appraisers. We pioneered further groundbreaking technologies to expose forgeries, establish accurate ownership histories, and safeguard the true value of artworks.
The Team
We have built a multi-disciplinary team of nine world-class professionals with impressive track records in the field of art, business, culture and technology. They stand ready to execute our business plan and create value for shareholders. Four of them hold PhDs in a variety of fields:
- Imaging Spectroscopy
- Hyperspectral Data
- Synthetic Chemistry
- Photogrammetry
Our Chief Heritage Scientist, Carolien Coon, is finalizing her doctoral thesis on “Photodegradation and nanotechnology-based conservation”.
