Index Exchange

Index Exchange runs a programmatic advertising infrastructure business focused on the sell side of the market. It creates value by aggregating premium publisher supply, connecting that inventory to broad demand sources, improving auction competition, and providing tools for curation, private deal execution, addressability, and analytics. This infrastructure enables media owners to increase yield and gives buyers more controlled access to inventory and transaction data.

Index Exchange is a Canadian advertising technology company operating an independent global supply-side platform for programmatic media trading. Its core business is helping publishers, app developers, streaming platforms, and other digital media owners monetise inventory through real-time auctions, private deals, curated marketplaces, identity solutions, and transparent analytics. It also serves agencies, advertisers, DSPs, and data partners through curated supply access, deal execution, and measurement capabilities.

The company makes money primarily by taking a share of advertising spend transacted through its exchange infrastructure. Its platform spans web, in-app, and CTV/OTT channels and supports display and video formats. Its commercial positioning centres on transparency, unified auctions, transaction-level auditability, and independent marketplace operation rather than ownership of media inventory.
