Koah's AI Advertising Platform: The Monetization Layer for Conversational AI

Theory Ventures leads Koah's $20.5M Series A funding round for an AI advertising platform that matches ads to semantic context within conversations rather than keywords. Koah demonstrates 7.5% average click-through rates (4-5x higher than display advertising) and has processed 170M+ queries over 12 months. The company represents a new advertising category emerging from the AI interface shift, similar to previous paradigm changes in TV, web, mobile, and streaming.
