It all started back in 1982 when two Northwestern University professors—our founders, Andy Zoltners and Prabha Sinha—had one big idea about optimizing efficiency.
Realizing the algorithm they collaborated on that was initially used to plan and distribute meals to feed astronauts and members of the U.S. military could be applied to sales force sizing and resource allocation, they presented their mathematical models to executives at the Pharmaceutical Management Science Association. That presentation was the catalyst for the birth of ZS in 1983.
Fast forward 35 years, and ZS is a leader in the industry helping companies improve their performance, grow revenue and market share, and deliver impact where it matters—directly to their customers.
Of course, a lot has changed since 1983. We’ve expanded into new practices to better serve our clients, established a global presence with 22 offices around the world and grown both in numbers and scale—recently surpassing the 6,000-person mark.
“Over the three decades I’ve been with ZS, it’s been amazing to see how we continue to grow and learn new things,” said Managing Director Chris Wright. “While so much has changed, the most important things—our culture, our values and the way we treat one another—have remained constant.”
Despite the growth and evolution of our firm, our one-of-a-kind culture that empowers ZSers to forge their own paths hasn’t changed. Our people collaborate to achieve shared success, and constantly innovate to improve both the way we work and the solutions we take to our clients.
We recently received kudos for our workplace culture, appearing on Consulting magazine’s Best Firms to Work For list and the Vault Consulting 50. Recognitions like these are a testament to the pride we take in our company culture, and confirm what we already feel to be true: that ZS is one of the best places to thrive in a successful, long-term career.
“Our firm belongs to our people and we’re constantly passing it from generation to generation,” said Chris. “The people we’re hiring today are the ones who will be leading the company in the next 35 years. If we continue to uphold our values and our culture, there’s no stopping what we can do.”
