Integration Brings Real-Time AI Decisioning to Premium Streaming TV Supply
Subjective, an AI-native data and curation platform for agencies and brands, today announced a real-time data integration with Index Marketplaces, Index Exchange’s omnichannel platform for curated, signal-rich supply activation and sell-side decisioning. The partnership brings Subjective’s agentic, real-time decisioning engine to Index Marketplaces, enabling marketers to easily create and activate smarter campaigns across premium streaming TV supply.
Through Index Marketplaces, Subjective applies intelligence at the point of impression, dynamically evaluating content signals, predictive audience characteristics, and campaign objectives in real-time. This allows marketers to reach the right audience at the right moment, while maintaining transparency, efficiency, and control across programmatic workflows.
Streaming TV ad spend is projected to soar past $37 billion in 2026, yet buyers still struggle with outdated targeting methods that rely on static segments and pre-defined rules. Subjective’s agentic decisioning engine operates differently: it continuously interprets contextual and supply-side signals as each impression becomes available, making independent, real-time decisions that adapt to live content, shifting audience dynamics, and performance feedback.
By building on Index Exchange’s powerful real-time infrastructure and high-quality, premium supply, Subjective helps marketers find more relevant impressions across traditionally underutilized inventory.
Subjective’s integration is now available via Index Marketplaces, allowing agencies and brands to activate campaigns seamlessly through DSP workflows, with no added platform fees or operational friction.
“CTV is unique in its power to engage audiences, but also in its complexity for outcome-focused advertisers. Subjective provides a bridge, leveraging AI and real-time decisioning to help better connect brands with their customers, and to measure the results.”- Lindsay Silver, Founder, Subjective
“Index Marketplaces is designed to enable partners to bring intelligence directly to the point of decision,” said Steve Roach, Head of Business Development at Index Exchange. “By integrating Subjective’s real-time decisioning capabilities, we’re enabling advertisers to apply advanced AI-driven strategies across premium streaming TV supply while preserving the transparency and efficiency that programmatic buyers expect.”
