What 74 Arbolus experts think of ZS Associates
The NPS scores are predominantly positive, spanning 7 to 10 for most users, especially among decision makers in pharma and life sciences. Renewal intent is strong among high spenders and influencers, with many citing ZS as an 'essential partner.' Stickiness is reinforced by the long implementation durations—most customers with over one year of use report high satisfaction and intent to renew. Key themes center on ZS’s reliability in analytics, innovation in digital engagement, and value as a strategic partner, balanced by feedback on cost and delays in customization.
