TopOn

TopOn provides B2B ad monetisation infrastructure for mobile app publishers. Developers integrate a single SDK and use the platform to connect multiple ad demand sources, manage bidding and waterfall logic, and monitor monetisation performance. In return, TopOn captures a share of ad revenue or a platform take-rate linked to the volume and performance of mediated impressions. Its value proposition is higher fill, higher eCPM, lower integration complexity and better reporting across networks.

TopOn is a Singapore-headquartered mobile advertising technology company focused on app monetisation. Its core offering is an ad mediation platform for mobile app developers, game studios and app publishers, combining bidding, waterfall management, reporting and SDK-based integration to help customers maximise ad revenue from in-app inventory. The company also provides analytics tools that track revenue, eCPM, LTV and retention across ad networks.

The business appears to monetise primarily through a revenue-share or take-rate model tied to mediated advertising demand rather than fixed software subscriptions. TopOn creates value by aggregating multiple ad networks into a single monetisation layer, reducing integration complexity and improving yield through optimisation, data visibility and cross-promotion capabilities.
