> Koah seeks a Product Designer to own advertiser and publisher experiences, including creative tools, dashboards, and SDK integration flows. The role involves designing AI-augmented workflows and ad format systems that adapt across various digital surfaces.

## Job description

## ABOUT KOAH

Koah is building AI–powered ad formats that work across any surface. In a chat app, a Koah ad feels like part of the conversation. On a publisher's website, it feels like editorial content. In a sidebar, a feed, an email – it adapts its layout, density, and tone to belong wherever it appears.

We're using AI to make ads better everywhere – composing the right format for the right surface with the right content in real time.

We're backed by Theory Ventures, live in AI apps serving millions of users, and we recently closed our Series A https://koahlabs.com.

## ABOUT THE ROLE

We're looking for a product designer to own the advertiser and publisher experiences – the creative tools, dashboards, and integration flows that make Koah work for both sides of the marketplace.

On the advertiser side, we're building toward a world where campaign agents do the heavy lifting – generating creative, selecting formats, optimising toward goals – and advertisers steer with goals and guardrails. You'll design the tools that give advertisers that power.

On the publisher side, you'll design the SDK integration experience – how publishers describe their surfaces, configure preferences, and see value from Koah.

You'll also shape the ad format system itself – how formats compose, adapt, and render across surfaces.

## WHAT YOU'LL DO

- Design the advertiser experience end–to–end – campaign creation, AI–assisted creative tools, reporting
- Shape how advertisers and campaign agents collaborate to produce and deploy ad creative at scale
- Design the publisher integration experience – SDK onboarding, surface configuration, performance dashboards
- Contribute to the ad format library https://format-library-demo.vercel.app/ – how formats adapt across different rendering contexts
- Connect the dots across advertiser tools, publisher surfaces, and end–user ad experiences

## YOU MIGHT BE A FIT IF

- You think in systems and can balance immediate user needs with long–term product vision
- You've designed for multi–sided products – marketplaces, developer tools, ad platforms, or similar
- You're excited about designing AI–augmented workflows, not just traditional dashboards
- You care about craft because it compounds into trust
- You're comfortable at the design–engineering boundary – schemas, structured data, component APIs
- You're comfortable moving fast without a full spec and drive clarity through design

## About Koah

## Company Overview
- **One-liner**: Koah builds the ad infrastructure for AI-native applications, enabling publishers to monetize AI chat and agent experiences with contextual, sponsored placements.
- **Entity Type**: Private (Seed Stage)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2024
- **Founders**: Nic Baird (CEO), Mike Choi, Herrick Fang

## 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
  - **Seed Round (October 2025)**: $5 million led by Forerunner, with participation from South Park Commons and AppLovin co-founder Andrew Karam.
  - **Series A (February 2026)**: $20.5 million led by Theory Ventures.
- **Key Metric**: Annual Revenue not publicly disclosed; early partners generating $10k in first 30 days.
- **Notable Investors/Partners**: Theory Ventures (lead Series A), Forerunner (lead Seed), South Park Commons, Andrew Karam (AppLovin co-founder). Advertisers include UpWork, General Medicine, and Skillshare. Publisher partners include Luzia, Heal, Liner, and DeepAI.
- **Growth Signals**: Headcount grew 633% year-over-year to 18 employees. Active job postings increased 66.7% quarterly. LinkedIn followers grew 744.8% year-over-year. The company is expanding its go-to-market team with a Founding Head of Ad Sales role.

## 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.

## Why Work Here
- **High-Growth Environment**: The company has grown headcount by 633% in the last year and is actively hiring across engineering, product, design, data science, and go-to-market roles.
- **Mission-Driven**: Employees work on solving a fundamental problem for the AI ecosystem — how to make AI apps profitable without compromising user experience.
- **Culture Values**: The company emphasizes "design for quality," "velocity over perfection," "experiment boldly," and "respect first." They value ownership, rapid iteration, and data-driven decision-making.
- **Work Policy**: Hybrid/on-site presence in San Francisco and New York. The Founding Head of Ad Sales role is listed as on-site in San Francisco or New York.
- **Team Composition**: Small, high-leverage team (18 people) with a flat structure. Technical roles (engineering, data science, product) make up a significant portion of the team.
- **Tech Stack**: Modern stack including React, TypeScript, Python, PostgreSQL, ClickHouse, Redis, Terraform, Cloudflare, and Grafana — appealing to engineers who want to work with cutting-edge infrastructure.
