Sabio launches platform covering 97% of UK household streaming behavior

This launch addresses the persistent transparency gap in the UK’s fragmented CTV market by providing a unified view of household behavior outside traditional walled gardens. As advertisers migrate budgets from linear to streaming, the ability to validate reach at a postcode level provides a concrete alternative to opaque, platform-specific metrics. This specifically shifts the market toward privacy-centric measurement that avoids the risks associated with individual device identifiers. Watch for whether Sabio's 21-million-household scale forces major UK broadcasters like ITV or Channel 4 to increase their own postcode-level data sharing to remain competitive in programmatic auctions.

The UK connected TV market is entering a phase of rapid expansion and structural maturity. Per IAB UK and PwC (March 2026), CTV advertising spend grew 21% in 2025 and is forecast to rise an additional 15% in 2026, reaching an estimated £2.31 billion. This growth is increasingly driven by a 'TV+' ecosystem where video advertising accounts for 23% of all digital investment. Despite this volume, measurement remains a primary hurdle; IAB UK reports that 31% of industry leaders cite the lack of standardization and market fragmentation as a top operational challenge for the current year.

Regulatory pressure is also reshaping how this data is utilized. Per the Information Commissioner’s Office (ICO, May 2026), new recommendations for the UK government advocate for a first-party-centric framework. This shift under the Data Use and Access Act, which took effect in February 2026, encourages privacy-preserving models that minimize third-party data sharing. Sabio’s move to a household-level graph aligns with these evolving standards, as buyers increasingly demand proof of quality and attention over simple impression volume.

Simultaneously, financial performance in the ad-tech sector highlights the flight to programmatic CTV. Per Sabio Holdings’ Q1 2026 financial results (May 2026), the company’s programmatic CTV revenues surged nearly 1,200% year-over-year, now representing roughly 24% of its total gross revenue. This momentum is supported by research from TVision (January 2026), which found that data-powered audience segments in CTV environments consistently exceed industry averages for attention-to-duration ratios, signaling that high-fidelity household data is becoming the baseline for premium ad placement.
