Case Study: Vainu.io achieves faster, actionable customer insights and prioritized product development with Lumoa

How Vainu got rid of manual time-consuming customer feedback analysis with Lumoa

Vainu.io, a sales-prospecting platform serving 1,500+ customers and 12,000 users, struggled as its fast growth made manual analysis of quarterly email and in‑app survey feedback too time-consuming, leaving little capacity to act on insights. To solve this, Vainu.io engaged Lumoa and adopted Lumoa’s customer feedback analytics to automate and scale their feedback analysis.

Lumoa’s service automatically categorized feedback after brief training and enriched results by linking responses to background variables (role, industry), while Lumoa’s team helped optimize feedback collection and boost response rates. The analysis revealed clear NPS drivers—showing, for example, higher satisfaction among users with Vainu’s CRM integration—so Vainu.io prioritized that rollout, reduced time spent on analysis, and shifted to fully addressing the most impactful negative drivers thanks to Lumoa’s insights.
