Koah specializes in connecting brands with over 100 million global users of generative AI (GenAI) through its innovative advertising solutions. The company's core offerings revolve around providing a platform where ads are integrated seamlessly into high-intent GenAI interactions, thereby enhancing user engagement and driving conversion rates.

The company primarily serves clients in North America, Europe, and Asia, focusing on industries that leverage digital advertising to connect with tech-savvy users, including technology, retail, and entertainment sectors. Koah generates revenue through a performance-based advertising model, where advertisers pay for placements in high-intent moments within the GenAI experience. This structure is designed to align the interests of advertisers with targeted user engagement, effectively translating into higher click-through rates compared to traditional media formats. The company's offerings allow businesses to execute campaigns across various customer journey stages, including top-of-funnel (TOFU), middle-of-funnel (MOFU), and bottom-of-funnel (BOFU) strategies. Advertisers can utilize Koah's platform for contextual ad placements, which are securely served from encrypted servers, ensuring both brand safety and user privacy. By integrating advertising seamlessly into the GenAI experience, Koah provides a unique value proposition that is attractive to brands looking to enhance their digital marketing effectiveness.
