Kontext

Kontext is an ad network for generative AI apps such as chatbots, AI search, character apps, video tools and games. It uses language models to read the context of each session and serve ad formats that fit the conversation, for advertisers and for publishers who want to monetize their apps.

The ad engine takes signals from text, images, video, audio and gameplay and fuses them in real time to pick a relevant placement. Publishers integrate a customizable ad server into their LLM interface, and advertisers reach an audience that skews toward Gen Z and Millennials across entertainment, search, dating and support apps.

Kontext says its network sees over a billion daily impressions, with CPM rates starting at $3 and click-through rates that it reports as higher than traditional channels. The company has raised a $10M seed round, and advertisers and publishers sign up through separate portals.
