Q&A
Frequently asked questions about Zest HR software
What’s the difference between an HRIS and Zest?
An HRIS manages HR administration: payroll, absences, contracts, onboarding. It records what has already happened. Zest does something different: it measures what your employees actually experience, detects early signals before they become real problems, and turns that data into concrete actions for your managers. The two are complementary. Zest connects natively to ADP, Talentsoft, and SAP SuccessFactors, so your data syncs without any manual re-entry.
How does this HR software handle reviews differently?
Most review tools exist to tick boxes and archive forms. Zest structures every review so it becomes usable data: objectives, linked OKRs, tracked feedback, evaluations consolidated into a People Review. Review completion rates rise on average from 45% to 87% among Zest clients, because the software makes the process simple for the manager, not just compliant for HR.
How is this HR software different from standard survey tools?
A survey tool produces response rates. Zest produces decisions. The difference comes down to three things. Our questionnaires are designed with psychometricians and occupational psychologists, which guarantees scientifically validated measurements that stay comparable over time. AI analyzes your verbatim comments and generates actionable recommendations directly within the software. And an exclusive sector benchmark shows you where you stand against your peers, not just against your own past results.
Is my HR data secure with this software?
Zest is hosted in France with OVH and is fully GDPR compliant. Your data stays on French soil and never leaves your hands. Zest’s AI model is proprietary: your data never feeds any external model. For organizations that prefer it, AI can be disabled entirely.
What role does AI play in this HR software?
AI in Zest analyzes your verbatim comments in real time and surfaces early signals, without any manual reading. It generates action recommendations directly within the software, so every manager knows what to prioritize without waiting for an HR analysis. The AI model is proprietary and hosted in France: your data never feeds any external model. It can be disabled on request.
How to choose an HR engagement and performance software?
A few criteria to check before you sign.
Scientifically grounded measurement. Have the questions asked of your employees been validated by experts, or generated empirically? The reliability of your decisions depends directly on the rigor of the measurement.
Software that saves time. Survey design, automated reminders, AI-driven verbatim analysis, reporting back to managers: every step should be streamlined, not added to your workload.
Human support included. Deploying a tool isn’t enough. Check whether HR experts are available to help you launch surveys, analyze results, and turn them into concrete action plans.
A solution suited to your structure. Headcount, field based populations, HRIS integrations: the software should adapt to your organization, not the other way around.
Your data hosted in France. Your HR data is sensitive. Check where it’s stored, whether it stays on French soil, and whether it feeds any third party AI models. Digital sovereignty isn’t a technical detail. It’s a prerequisite.
