Success Story

Explore our standout customer stories

With Zest, you can’t hold a performance review until the employee has initiated and started working on their own self-assessment. It’s always the same principle: I start with the employee and work up from there. That’s what made me choose Zest.

Group HR Director

In a word, Zest is a very easy tool to use. And it’s a tool that helps us build on what we do well.

I recommend Zest. It is a comprehensive platform with a modern, intuitive design that fully meets today’s standards.

Coralie Delfosse

Director of HR Development and Transformation

With Zest, you’re not just buying a platform. You gain a partner who helps us read weak signals, prioritize issues and turn complex results into very concrete action plans for our managers.

Philippe Besançon

Group HR Director

This is the innovative solution we were looking for to amplify the voice of our employees. It is a modern, user-friendly platform that makes us more responsive and breaks away from traditional surveys. It supports collaborative initiatives and delivers concrete results that are accessible at local level.

Anne-Marie Cesari

Head of Customer and Employee Excellence

Essential and complementary. For us, knowing what employees think, giving them a space where they can speak freely and listening to them is vital.
