Integral Stream

The business operates a programmatic marketplace and yield-optimisation platform for CTV/OTT and AVOD/FAST publishers. It creates value by aggregating CTV inventory, running unified header-bidding style auctions where multiple demand sources and ad formats (video and banner) compete, and by providing controls for open auction, private marketplace and programmeatic guaranteed deals. Publishers use the platform to increase fill rates and effective CPMs, while advertisers and agencies gain access to addressable CTV inventory via programmatic buying workflows.

Revenue is generated primarily through a percentage take-rate or revenue share on media spend flowing through the platform, aligned with typical SSP/CTV infrastructure economics. The company also positions campaign management, planning and other professional services for both publishers and advertisers, which can add fee-based or retainer revenue streams on top of transaction income. Machine-learning driven optimisation and analytics functions are bundled into the platform rather than sold separately as standalone software licences.

Integral Stream is a Bulgaria-based programmatic advertising technology company focused on connected TV (CTV) and OTT inventory. Its core platform provides a header-bidding style unified auction environment where video and banner formats can compete for the same CTV ad slots, supporting open auctions, private marketplace deals and programmeatic guaranteed campaigns.

The company generates revenue by operating as a supply-side and yield-optimisation platform for CTV and streaming publishers and as a transaction venue for programmatic buyers such as agencies, demand-side platforms and brand advertisers. It offers tools for yield management, fraud and brand-safety integrations and real-time reporting, and likely charges revenue shares or fees on media transacted through its marketplace, with potential additional fees for managed media or professional services.
