History

ZS Associates was founded in 1983 by a team with academic and corporate backgrounds drawn from Northwestern University, University of Chicago, INSEAD, Kellogg School of Management, and University of California, Berkeley networks. Early engagements linked the firm to Pfizer, Merck & Co., Eli Lilly and Company, Novartis, and GlaxoSmithKline as pharmaceutical companies sought quantitative methods used in Operations Research and Management Science. During the 1990s the firm expanded its use of Conjoint Analysis and Customer Relationship Management frameworks amid the rise of Oracle Corporation, SAP SE, and Siebel Systems. The 2000s saw entry into biotechnology and medical devices markets alongside partnerships with Genentech, Amgen, and Medtronic. ZS Associates grew globally through office openings in London, Bangalore, Singapore, and Sydney, while adopting technologies from SAS Institute, IBM, Microsoft, Google, and Amazon Web Services. In the 2010s and 2020s the firm broadened capabilities in artificial intelligence, predictive analytics, and real-world evidence working with organizations such as FDA, EMA, World Health Organization, and leading academic centers including Harvard Medical School, Johns Hopkins University, and Stanford University.
