OpenSincera

OpenSincera operates as a B2B advertising data utility. It gathers and structures metadata about digital ad environments and distributes that data through an API for integration into analytics workflows, programmatic systems and internal models. Rather than charging directly for access, the platform creates value by reducing information asymmetry in the open-web advertising ecosystem and by strengthening the surrounding infrastructure used by buyers, sellers and measurement teams.

OpenSincera is an advertising metadata platform focused on the open internet. Following The Trade Desk's acquisition of Sincera in 2025, the business was relaunched as OpenSincera to provide objective, standardised data on ad experience and programmatic supply-chain quality, including metrics such as ads-to-content ratio, ad refresh behaviour, supply paths and publisher health indicators.

The platform is API-first and is aimed at business users such as adtech developers, DSPs, SSPs, analytics teams and publisher monetisation teams. OpenSincera is positioned as free for the industry, so its commercial role appears to be strategic rather than directly monetised: it creates value by improving transparency and decision quality across open-web advertising, while indirectly supporting The Trade Desk's broader demand-side platform and open-internet market position.
