Forerunner-backed Koah Launches: AdSense for GenAI

Koah brings new revenue streams to liberate GenAI chat apps from subscription-only monetization.

As the global population adopts GenAI, multiple sustainable revenue models must exist in order to support GenAI apps — from indie developers to weekend vibe-coders, app studios, and major model providers. Beyond subscriptions, the fastest, easiest, and most scalable revenue stream for the internet has always been advertising.

That’s why Koah integrates advertising directly into GenAI chat.

Koah enables GenAI chat apps to show native, context-aware ads that appear inside conversations. Ads are relevant to user intent, integrated into the flow of chat, and proven to generate strong revenue without degrading UX.

• GenAI ads drive an average of $10 eCPM

• Engagement rates are 3–5x higher than internet display ads

With Koah now bringing a scalable monetization model to GenAI chat, apps can be more flexible, scalable, and investible.

“Koah is building the essential monetization layer in Consumer AI, filling an immediate need for varied, flexible revenues beyond consumer subscription. Koah’s model unlocks a new class of performance advertising that blends the contextual relevance of search with the native feel of social, but embedded seamlessly within chat-based discovery experiences.” Nicole Johnson, Partner at Forerunner

Koah: Proven in GenAI Apps

Koah has rolled out across GenAI chat apps reaching millions daily, including Liner, Luzia, DeepAI, and Heal. Developers, publishers, and advertisers generate revenue without harming UX, delivering sponsored recommendations at the exact moment of query intent.

“With Koah, we were able to instantly launch relevant, sponsored answers in Luzia’s AI assistant across millions of weekly queries throughout LATAM, Europe, and the USA. Koah delivered meaningful revenue while giving our users access to helpful products.” Natalia Solano Gutierrez, Head of Product at Luzia

Early GenAI app partners averaged $10,000 in their first 30 days working with Koah.

Developer-First by Design

Koah is built to make monetization simple for developers:

• Lightweight SDK → Flexible, deployable in under 1 day

• Context-aware formats → Native to the chat flow

• Scales with you → Works whether you have 10K or 10M sessions/month

“Since adopting Koah's cutting-edge ad formats, we've consistently increased CTR and coverage, without eroding any of the trust at the core of our product.” Luke Kim, CEO of Liner

Koah Origin Story

Koah was founded at South Park Commons by veterans of consumer and martech who recognized a familiar pattern: powerful new engagement channel, no native monetization layer. With backing from Forerunner, South Park Commons, and AppLovin cofounder Andrew Karam, Koah was built to fill the monetization gap for GenAI from day one.

"We’re here to democratize revenue for all GenAI app developers big & small. Ads are the best and easiest way for any new GenAI apps to turn on a revenue stream instantly." Nic Baird, CEO of Koah

As billions of queries shift from browsers into chat apps, GenAI chat is becoming the default interface for search, comparison, and action online. Koah is the economic layer for this new paradigm.
