How Zefi works
Your feedback sources,
enriching each other automatically.
Most tools dump everything into a single bucket and call it "centralised." We do something harder: we deduplicate, clean noise, normalise, and reconcile your data sources so they inform each other. Every new integration makes the whole system more granular, while staying navigable at the strategic level.
"Zefi helps us turn customer feedback scattered through many channels into one source of truth. It works as our VoC control tower"
Yujia Cao
Head of Research & Insights @ Kiwi.com


Structure the unstructured data. Bridge qual & quant and get the why behind your customers' interactions.
Bridge qualitative and quantitative. Control the logic of the data that feeds your agents — so you can build trustable automations even for large, complex pipelines. We don't just categorise feedback. We help you own the taxonomy so your AI-driven workflows stay accurate, auditable, and scalable.
"Zefi enables us to create custom dashboards to identify areas for improvement and valuable insights. It's outstanding."
Claire Pauze
Customer Operations Team Leader @ Qomodo


Stay ahead of your customers. Act proactively on their feedback thanks to a company-wide operating system.
Close the loop with a structured, best-in-class framework to monitor, strategise, and share across your org. Proactively manage workflows for cutting operative costs, improving experience, and finding growth opportunities before your customers have to tell you twice. Stay ahead. Act proactively. Move and prove your customers KPIs.
"We changed our approach towards customer feedback from reactive to proactive. Zefi has been instrumental in this change."
Sonia Ferrón Sáenz
Customer Experience & Quality Manager @ Wallapop
