About Us

ArtTactic is a progressive art market analysis firm that offers dynamic and bespoke market intelligence on the fast-paced and ever-changing global art market.


ArtTactic was founded in 2001 by Anders Petterson, and the first art market research company to use crowd-sourcing as the main tool for collecting qualitative and quantitative data on the art market. From the outset, our goal was to build a global art market intelligence network of thousands of knowledgeable, experienced and talented individuals. This goal has already been achieved, but we are not stopping here, and the launch of ArtTactic Forecaster in 2015, has further expanded our crowd sourcing initiatives and the growing pool of innovative and new art market data that we believe will support the call for more transparency in the art market.
