Koji

Pre Seed · Ai · Rotterdam, Netherlands · 1–10 employees

Koji is an AI-native customer research platform that automates qualitative user research at scale. The platform conducts natural, in-depth voice and text interviews using AI moderation, replacing traditional surveys and expensive manual interviews. Koji generates research goals, discussion guides, and interview questions automatically, then runs hundreds of asynchronous interviews where participants respond on their own time. The AI interviewer asks smart follow-ups and probes for depth in real-time, producing individual interview analyses and cross-interview synthesis with themes, patterns, and recommendations—all delivered in under 48 hours instead of weeks. The platform is GDPR-compliant with EU data residency, backed by Google for Startups and ElevenLabs Grants, and offers a freemium model with voice interviews as a premium feature.
