GSI

The business provides B2B advertising quality software that detects fraudulent traffic across digital advertising environments. It creates value by ingesting campaign or traffic data, applying proprietary tracking and analysis methods, and returning actionable outputs such as blacklist generation, reporting, and system-ready API data. Revenue is generated primarily from recurring access to the platform, with additional value capture from integrations, managed analysis, and bespoke enterprise support.

GSI is a Germany-based anti-ad-fraud platform operated by GP One GmbH. The product analyses digital advertising traffic to detect invalid impressions, clicks, anonymised traffic sources, and affiliate manipulation. It integrates with client systems via API, generates operational outputs such as blacklist rules and reports, and is positioned for advertisers, publishers, ad networks, and performance marketing teams seeking to reduce wasted media spend and improve traffic quality.

The company appears to monetise through recurring software fees, API-enabled usage, managed analysis services, and customised enterprise arrangements. Its value proposition is built around proprietary multi-stage tracking, a large daily updated anonymisation database, and outputs that can be used both for campaign optimisation and, in some cases, legal evidence. The available data suggests a focused B2B software business in ad verification rather than a general media agency product.
