What Adserver.Online does

Adserver.Online is a privately-held SaaS ad-serving and ad-management platform headquartered in Tallinn, Estonia, founded in 2015. The platform delivers display, video, native, and programmatic advertising across websites, mobile apps, CTV, OTT, DOOH, podcast, email, and listing inventory. Its technical stack centers on a cloud-native architecture with REST Management and Reporting APIs, a JavaScript ad tag API, OpenRTB v2.5/v2.6 endpoints, XML/JSON programmatic feeds, VAST/VMAP/VPAID/SIMID video support, and SDKs for Android and Prebid header bidding. White-label, real-time analytics with 30+ dimensions and 35+ metrics, and IAB TCF v2 GDPR/CCPA compliance are positioned as standard features rather than paid add-ons.

The platform serves four primary customer segments — publishers, advertisers, ad networks, and agencies — with affiliate marketers as a secondary segment, pursuing a horizontal use-case segmentation approach. Customer-facing modules include a Display Ad Server, Video Ad Server, Ad Network Builder, Programmatic Ad Server, API Ad Server, and Ad Tracker, all built on a common platform foundation. The go-to-market is product-led growth through a self-serve 14-day free trial with no credit card required, complemented by API-first distribution for developer-driven and enterprise use cases and a sales-assisted route for custom enterprise requirements.

Revenue is generated through tiered usage-based monthly subscriptions — Starter at $49/month for 1 million requests, Premium at $199/month for 10 million requests, and Ultimate at $599/month for 50 million requests plus 15 million empty RTB requests — with overage billing on usage beyond plan limits. Paddle.com serves as Merchant of Record for global billing. The company operates without disclosed external funding, M&A activity, or subsidiary structure, suggesting a bootstrapped, independent operating model with a small team of 1-10 employees.
