The story

Zest is a French HR SaaS company focused on employee engagement, performance management, and continuous feedback (surveys, annual reviews, OKRs, 360 feedback, people reviews). It is a pure HR-tech play — not an embedded finance company. Its differentiators are French sovereignty (OVH hosting, GDPR-native), scientific validation of survey instruments, and a proprietary in-house AI model. Serves 400+ enterprise clients across 35+ countries.
