ABOUT KOAH

Koah’s mission is to create the best sponsored experiences for the generative internet. We’re first building an ad network for AI and providing AI products a way to monetize without breaking the experience. We’ve raised $26M to date, backed by Theory Ventures, Forerunner, and South Park Commons.

THE ROLE

As Developer Relations at Koah, you will help developers discover Koah and build developer support for native ads monetization.

You will be the hands-on technical voice for Koah in the builder community. We are not rigid about the playbook. Whether you are building sample apps, hosting founder dinners in SF and NYC, posting on Twitter/X, or hanging out at hackathons, making merch, you have full ownership to do whatever gets developers excited and building with Koah.

WHAT YOU WILL DO

Shape how developers discover and engage with Koah, bringing a strong point of view grounded in real-life experience and user feedback.
Drive community and content initiatives using data, feedback, and business priorities.
Work with EPD to turn developer feedback into real roadmap improvements.
Happier developer customers for our SDK products
Partner with GTM and Marketing to support developer-focused campaigns that drive adoption.
Help define what world-class AI Ad developer relations looks like.

ABOUT YOU

You can build real demos, create apps, and talk with engineers and technical founders.
You are technically credible. You know where builders hang out and what they care about.
You are connected in the ecosystem. You enjoy being on the ground in SF, New York, and major builder hubs to connect with founders and teams directly.
You are a fast learner: AdTech is its own unique world. You do not need prior ads experience, but you have the curiosity and speed to ramp up quickly.

NICE TO HAVE

Previously founded a company.
Prior experience in DevRel, developer marketing, community building, or building your own project.
Background in ad tech, creator monetization, or developer tools.

Core Business

Primary Industry: Advertising Technology (AdTech) / Generative AI Infrastructure
Target Customers: B2B — serves both AI app publishers (developers and companies building AI chat/agent experiences) and advertisers (brands seeking high-intent, context-aware ad placements).
Mission/Purpose: To create the essential monetization layer for consumer AI services, making it possible for AI-native apps to be profitable at scale without relying solely on subscriptions.

Products & Services

Koah Ad Network: A native advertising platform designed specifically for generative AI environments. Publishers embed a JavaScript snippet or SDK to serve contextual, sponsored content directly inside chat and agent conversations. Advertisers can reach users in moments where AI is shaping their decisions, with clickthrough rates reported at 7.5% (4x-5x higher than traditional display ads). Early partners have earned $10,000 in their first 30 days on the platform.

Market Standing

Total Funding: $25.5 million

Competitive Advantages

Native AI Ad Format: Unlike older adtech companies (AdMob, AppLovin) that try to retrofit display ads into AI, Koah builds ads that are contextually embedded within the conversational flow, making them additive rather than disruptive.
High Performance: Delivers 7.5% clickthrough rates (4x-5x better than traditional ads) with less detrimental effect on user engagement.
First-Mover in a Growing Market: As the "long tail" of AI apps built on top of large models expands, Koah positions itself as the essential monetization layer, solving the "elephant in the room" of how to make consumer AI profitable globally.
Strong Investor Backing: Backed by top-tier VCs (Theory Ventures, Forerunner) and a successful adtech founder (AppLovin co-founder), providing both capital and deep industry expertise.

Strategic Focus

Monetization Infrastructure for AI: Koah is focused on becoming the default ad network for the generative AI ecosystem, enabling "vibe coded" apps to operate at scale without requiring VC funding or subscription-only models.
Global Expansion: The company is targeting apps with user bases outside the United States, recognizing that subscriptions alone don't work for global audiences.
Product Development: Building out the SDK, API, and developer tools to make integration seamless for publishers, while refining ad targeting to capture "commercial intent" within AI conversations.
