ZS is a global management consulting and technology firm that partners with companies to improve life and how we live it. Founded in 1983 by Northwestern University professors Andy Zoltners and Prabha Sinha, we have grown from a sales force analytics pioneer into a firm of more than 15,000 professionals operating across 40-plus offices worldwide. We transform ideas into impact by bringing together data, science, technology and human ingenuity to deliver better outcomes for all. Everything we do is designed to strengthen your business strategy and product portfolio, turning insight into action and unlocking new opportunities for growth. We bring together deep consulting experience, a network of technology partners and our own ready-to-use products and digital accelerators to help you turn plans into progress. From healthcare and life sciences to high-tech, financial services, consumer goods, retail, travel and beyond, our domain expertise ensures that solutions work in the real world. We partner with you across every stage of your journey — from defining the right strategy and use cases to building, deploying and scaling solutions across the enterprise. We ensure the right data, technology, governance and talent are in place to create both practical and transformative success. Because true transformation isn't just about what's next — it's about what's meaningful and lasts.

ZS is the place where ambitions are welcomed and where passion changes lives. Our principles — Treat people right, Get it right, Do the right thing — were set by our founders and serve as the foundation for every decision we make. We believe in treating others with dignity and respect, providing a supportive, collective culture that inspires action. With more than 40 offices worldwide across the Americas, Europe and Asia, ZS connects local expertise with global collaboration. Our people — consultants, data scientists and technologists — are passionate about helping clients and communities thrive. Every ZSer brings a client-first mentality to each engagement, collaborating to develop custom solutions and technology products that create real, lasting value. A supportive community, trust, empowerment, humility, innovation and a quest for continuous improvement are the hallmarks that underpin our culture.

We combine data, science, technology and human ingenuity to develop consulting solutions, tech solutions and products that work in the real world. Our capabilities span strategy and transformation, research and development, marketing, sales, customer experience, market access, supply chain and manufacturing, and data, digital and technology. We apply AI, advanced analytics and deep domain expertise to help clients across life sciences, healthcare, technology, financial services, consumer goods and retail, and travel and hospitality make smarter decisions, accelerate growth and improve outcomes for patients, consumers and businesses alike.

Our purpose is simple and enduring: to improve life and how we live it. This drives every engagement, every innovation and every decision we make. From helping pharma companies bring life-saving therapies to patients faster, to enabling retail brands to build deeper customer relationships, to empowering health systems to deliver better care — every project we take on is grounded in this commitment to creating a better world.

Three principles set by our founders guide every experience and action at ZS: • Treat people right — We believe in treating others with dignity and respect, providing a supportive, collective culture that inspires action. • Get it right — We apply industry expertise, leading-edge analytics, technology and strategy to bring bold ideas to life. • Do the right thing — Our commitment to ethics empowers our people to act with integrity and confidence.

ZS differentiates through four core strengths. First, deep industry expertise: we lead the way in combining science and hands-on experience to solve the toughest business challenges, with especially deep roots in life sciences and healthcare built over four decades. Second, analytics and AI: we use leading-edge analytics, generative AI and build robust software solutions that don't just recommend but execute. Third, solutions that work: it's about results, not just ideas — we don't stop until the solution works for our clients. Fourth, a proprietary product ecosystem: ZAIDYN, our AI-powered life sciences intelligence platform, and Max.AI give clients ready-to-use technology that connects insight to execution at global scale. Recognized as Forbes' top management consulting firm and a Leader in Everest Group, Forrester, IDC and Gartner assessments, ZS ranks in the top 5% globally for sustainability by EcoVadis.

We strive to deliver healthy and sustainable outcomes by integrating environmental, social and governance (ESG) priorities into our work, partnerships and operations. In 2024, the Science Based Target initiative (SBTi) validated our 2045 net-zero target, and approved our near-term GHG emission reduction targets to achieve a 48.8% absolute reduction of Scope 1 and 2 emissions and a 55% reduction of Scope 3 emissions per FTE by 2030 (both versus our 2019 base year). We publicly report progress via our annual ESG report and through CDP and EcoVadis, where we rank in the top 5% globally. As of 2025, all of our offices are ISO 14001-certified, and our sustainability governance is driven at the executive level through our Business Responsibility & Impact Core Team.

Placing health equity at the heart of our business is key to improving health outcomes for all. Through ZS Cares, our global social impact program, we invested $5 million in partnerships through patient health and equity (PHE) projects and social impact initiatives. More than 2,000 ZSers served over 40,500 hours volunteering and conducting pro bono consulting for charitable causes, and ZSers raised nearly $825,000 for more than 450 causes through the ZS Donation Match Program. We have joined 40-plus organizations in signing the World Economic Forum's Zero Health Gaps Pledge and the Healthcare Leadership Council's pledge to advance health equity. Our community partnerships have the potential to touch millions of lives across education, healthcare, clean environments, good nutrition and economic stability.

Inclusion drives innovation at ZS. We welcome and celebrate the visible and invisible elements of our identities, experiences and belief systems, cultivating a lived experience where every ZSer receives support, feels heard and respected, and is enabled to thrive. ZSer-led communities including Women@ZS, and our broader diversity, equity and inclusion initiatives, support every individual in building a successful, long-term career. The Human Rights Campaign Foundation has recognized ZS for earning 100% on their Annual Corporate Equality Index for LGBTQ workplace equality. We are committed to building a team that reflects a broad variety of backgrounds, perspectives and experiences — and to giving every ZSer the freedom to define their own path.
