Explained: Index Exchange’s Marketplaces product
Index Exchange has unveiled Marketplaces, a product enabling media and ad-tech firms with unique data, formats, or KPIs to curate inventory and transact across Index’s publisher exchange. In a Marketecture interview, CEO Andrew Casale explains how Marketplaces works and where it sits in the programmatic landscape, noting that competing solutions include Xandr Curate and Criteo CommerceGrid. Casale frames Marketplaces as a response to a market in which buyers have consolidated bidding with a few leading DSPs and publishers lack bandwidth to directly integrate with many vendors. By aggregating demand across what he calls the fattest possible programmatic pipe, the product aims to scale campaigns and optimize spend. The discussion highlights positioning against incumbents and the broader trend toward more flexible, data-driven inventory orchestration.

Revolutionizing Sell-Side: Index Exchange's Vision for AdTech
In an interview with ADZINE, Andrew Casale, founder of Index Exchange, discusses the evolution of digital advertising from primitive networks to a data-driven, sell-side–focused programmatic ecosystem. Index Exchange shifted from the buy-side to the sell-side to empower publishers and aims for 'total market efficiency' with low transaction costs. The platform handles about 6.5 million requests per second, while Visa handles roughly 30,000 requests per second, underscoring real-time, data-driven auction dynamics. Casale highlights the rise of Curation, where publishers package data and inventory to enable targeted selling, and envisions the sell-side driving innovation previously confined to the buy-side. He notes growth in Connected TV, live ad synchronization, and a move toward cookieless privacy approaches and cleanrooms. He also emphasizes collaboration with Google, which operates on both sides of the ecosystem, and expresses optimism about an open internet that accommodates multiple innovators.
Index Exchange CEO: Sell-Side Innovation, CTV Transparency, AI Agents
In an interview with ADZINE, Andrew Casale, CEO of Index Exchange, discusses the evolution of programmatic advertising. He argues that sell-side innovation, including modeling and containerization, is increasing complexity but also value. Buyers can now run their own models on the sell-side, democratizing decision-making. Casale addresses the black box concern, noting that while the internal logic of buyer models is opaque, the platform observes their actions. He highlights the shift towards modular infrastructure, with Index enabling data providers and DSPs to run modules on its cloud. Regarding CTV, Casale emphasizes the need for more transparency, noting that while genre data is increasingly available, show and episode data remain limited due to legal and distribution issues. He discusses the evolution of pod serving and the role of agentic advertising, distinguishing between workflow automation and impression-level decisioning, which remains the domain of mathematical models. Casale sees AI agents as useful for automating manual tasks but not as a revolution that will shift power from walled gardens.
