Koji

What is Koji?

Koji is an AI-native customer research platform built in Amsterdam. Its AI moderator interviews customers by voice, chat, or phone, asks follow-up questions to find the reasons behind answers, and speaks more than 30 languages. Results arrive as themes, sentiment, and quotes, so a full study can finish in hours.

Top Features:

• Study design agent: builds questions and an interview guide from your goal.
• Adaptive probing: follows up on each answer to uncover the real why.
• Automated analysis: clusters themes and sentiment, linking each finding to quotes.

Use Cases:
