Kvar is the attention marketplace for AI wait states. We believe the most concentrated developer attention on Earth happens during the seconds — sometimes minutes — when an AI model is thinking, and the human is waiting, staring at a single line.
We built Kvar to capture that attention ethically: publishers (developers) earn passive income from their wait time, and advertisers reach an engaged, high-intent audience. Both sides have full transparency and control.
Existing "ads in your IDE" products treat developers as inventory. We treat them as publishers — they own the inventory, they control the experience, and they earn the majority of the revenue.
We also saw a gap in contextual targeting. Blind impressions are worth pennies. But an impression shown to a developer who actively uses Postgres, while they are waiting for an AI model, is worth dollars. Contextual targeting by detected stack is our core differentiator.
The Kvar extension client is open source. The telemetry schema is published. The auction is verifiable. We believe trust is earned through transparency, not marketing.
Kvar is built by a small team of developers who spend most of their time in AI coding surfaces. We built the product we wanted to use ourselves.
