Adwatch

Adwatch operates a B2B adtech software model centred on independent measurement, verification and auditability. It creates value by ingesting campaign event data across multiple parties, applying rule-based validation and producing a tamper-resistant record that customers can use to detect fraud, resolve discrepancies and evaluate inventory quality. In addition to the core platform, it extends this model through service-led assessments and a certification programme for publishers.

Adwatch is a Spanish B2B adtech company that provides campaign verification, fraud detection and measurement transparency software for the digital advertising supply chain. Its platform records advertising events, applies campaign-specific rules and gives buyers and supply-side participants an auditable view of how ads were delivered across partners. The company appears to position itself as an independent source of truth for campaign data rather than as a media seller or buying platform.

The business serves advertisers, agencies, publishers and adtech intermediaries such as DSPs, SSPs and exchanges. Revenue appears to come from a hybrid of software access and managed services, including campaign assessments and publisher certification. Its commercial value proposition is reducing waste, identifying fraudulent or non-human traffic, and improving trust in campaign reporting and inventory quality.
