The story
Founded by Stephen Fodor in 1992.1
Affymetrix, Inc. was spun-off from Affymax Research Institute by Alex Zaffaroni in 1993, and was eventually based in Santa Clara, California, United States. It began as a unit in Affymax N.V. in 1991 under Fodor and his group. In the late 1980s, that group had developed methods for fabricating DNA microarrays, under the "GeneChip" Affymetrix trademark, using semiconductor manufacturing techniques. The company's first product, an HIV genotyping GeneChip, was introduced in 1994 and the company went public in 1996.
