About AdFlight
Established in 2022 and based in Washington, D.C., AdFlight operates as a B2B ad server platform. The company provides a suite of ad-serving APIs designed for developers and publishers to construct their own custom ad servers. This approach allows clients to manage and integrate advertising capabilities directly into their products with a high degree of control.
AdFlight's business model is subscription-based, offering several tiers of service that scale with the volume of ad requests, from millions to over a billion per month. The platform makes money by charging monthly fees for access to its API and infrastructure. Its target clients range from small publishers and individual developers to midsize businesses and enterprises looking to implement tailored advertising solutions without building the core technology from the ground up. The service is designed for those who need to serve native ads, sponsored listings, promoted content, or even internal promotions within their own digital environments.
The core of the product is a collection of APIs, including a Decision API, Management API, and Reports API. These tools enable functionalities such as campaign management, budget pacing, event tracking, and detailed reporting. A key feature is that the platform delivers ads as a JSON response, giving developers full control over the ad unit's final appearance and integration, without data leakage or unwanted cookies. AdFlight supports various ad formats, primarily focusing on native ads, sponsored content, and promoted listings, but it can also handle standard display ads. The platform boasts a global infrastructure with data centers across three continents to ensure low latency, with API response times under 100ms.
