OnAudience

A leading third-party audience data marketplace in Central and Eastern Europe, with global data distribution through major programmatic platforms.

OnAudience was a data-driven advertising technology company founded in Poland that operated as both a Data Management Platform (DMP) and a global audience data marketplace. The company specialized in collecting, processing, and packaging behavioral and demographic audience data into targetable segments for use in programmatic advertising campaigns. OnAudience built one of the largest third-party data marketplaces in Central and Eastern Europe, offering advertisers, agencies, and publishers access to hundreds of pre-built audience segments spanning interests, purchase intent, demographics, and more. The company's platform enabled clients to leverage audience insights for more precise ad targeting across display, video, and mobile channels. OnAudience distributed its data through major Demand-Side Platforms (DSPs) and data exchanges, including integrations with platforms like Oracle Data Cloud, Salesforce DMP, and various programmatic ecosystems. Its data assets were particularly strong in European markets, where it had established robust data collection partnerships with publishers and media companies. OnAudience was part of the Cloud Technologies group, a Polish AdTech holding company. Over time, as the third-party cookie deprecation narrative intensified and the data marketplace landscape consolidated, OnAudience's distinct brand and operations were wound down or absorbed. The company's legacy reflects the broader challenges faced by third-party data providers navigating privacy regulation changes such as GDPR, which significantly impacted the European data brokerage and audience targeting industry.
