Client Overview
Zonka Feedback is a SaaS customer experience platform that helps businesses measure and act on customer satisfaction across every channel. The product serves 2,000+ brands across 30+ countries — from healthcare providers and retail chains to SaaS companies and financial institutions.
Classic Informatics was engaged to build the platform from the ground up. The goal was to create a product that enterprise clients could use to run multichannel feedback programmes, track NPS, CSAT, and CES, and close the loop on every response — all from a single tool.
The Challenge
- The platform needed to support feedback collection across a wide range of channels — email, SMS, WhatsApp, website, in-app, and offline — each with its own delivery logic and response handling
- Survey triggers had to be event-driven, firing automatically off actions in external tools like CRMs and helpdesks, rather than relying on manual sends
- NPS, CSAT, and CES needed to be measured consistently across all channels in a single reporting layer — not tracked separately per tool
- Enterprise clients required the ability to route, assign, and resolve responses within the platform, with automation rules to handle volume at scale
- The product had to support deep integrations with the tools enterprise CX teams already use, from Salesforce and HubSpot to Zendesk and Intercom
Our Approach
1. Channel-first architecture
We built the platform so that each delivery channel — email, SMS, WhatsApp, website, in-app, offline kiosk — was a first-class citizen with its own delivery and response logic, rather than retrofitting one channel framework onto others.
2. Event and behaviour-driven triggers
We built automated survey triggers connected to real customer events in external tools — a closed support ticket, a completed purchase, a product milestone — so the product could serve surveys at the most relevant moment without manual effort from the client's team.
3. Unified CX metrics layer
NPS, CSAT, and CES were built with consistent measurement logic across all channels from the start, giving end users a single, accurate view of experience performance rather than disconnected per-channel reports.
4. Closed-loop workflows by design
Response routing, ownership assignment, and automated follow-up were built into the core product architecture — not added later — so every response collected by the platform has a clear path from receipt to resolution.
