WinSim is solely dedicated to the furtherance of the DESIGN II for Windows software, originated from ChemShare Corporation.

The ChemShare Corporation started marketing the DESIGN program in 1969. In the 1970s, the Distill program was written and added to DESIGN to create the product DESIGN 2000. In the late 1970s / early 1980s, the Refine program was written and added to the DESIGN 2000 to create the product DESIGN II.

In 1995, several ChemShare employees formed WinSim Inc. An agreement was reached with ChemShare Corporation to purchase an exclusive worldwide license to market and develop DESIGN II Simulation Systems. This action created the business structure to focus and build on the 26 years of ChemShare’s outstanding service to simulation clients.
