Boldwin

The business operates an in-app monetisation and supply-side platform stack for publishers. It provides a lightweight SDK for Android, iOS and Unity that exposes multi-format ad inventory and routes it into its own SSP and connected demand sources. The SSP runs real-time auctions, performs floor and yield optimisation, and connects publisher inventory to programmatic buyers. Value is created by improving effective CPMs and stabilising sRPM for publishers via auction intelligence and optimisation algorithms, while reducing integration complexity through compatibility with major mediation platforms. Revenue is primarily earned as a percentage of ad spend flowing through the SSP, aligning its incentives with publisher yield, with possible incremental income from managed services and technical support.

Boldwin is an Israel-based advertising technology company providing a publisher-focused in-app monetisation stack built around a supply-side platform and mobile/OTT SDK. Its technology supports multiple ad formats (banner, video, interstitial, rewarded) from a single ad unit, integrates with major mediation platforms, and applies real-time bidding and floor optimisation to stabilise and increase publishers’ revenue.

The company generates income by taking a revenue share on programmatic advertising transactions processed through its SSP and SDK, and may additionally charge for managed yield-optimisation and integration support. Its customers are mobile and OTT app publishers and studios, particularly those using mediation platforms and seeking more predictable in-app advertising revenue across formats and regions.
