About

Index Exchange is a global programmatic advertising marketplace founded in 2001 in Toronto, Canada, originally as a traditional ad network and reborn as one of the industry's most trusted independent supply-side platforms. The company's core technology provides publishers with a transparent, high-performance programmatic auction infrastructure for selling display, video, and connected TV advertising inventory, with a strong emphasis on data privacy, header bidding innovation, and clean supply chain practices in an industry often criticized for opacity.\n\nIndex Exchange's platform connects thousands of premium publishers with hundreds of demand-side platforms and agency trading desks, facilitating billions of daily ad transactions across web, mobile, and CTV environments. The company's Header Tag technology was ranked the most widely used header-bidding solution in 2024, reflecting its deep integration into the publisher technology stack. Index Exchange differentiates through its commitment to transparency — providing buyers with detailed supply path information and working to reduce the intermediary layers and fraud that inflate costs across programmatic ecosystems.\n\nIndex Exchange generated between $127 million and $176 million in revenue in 2025 and received Frost & Sullivan's 2025 Innovation Award, underscoring its continued product investment in a consolidating industry. As privacy regulations reshape digital advertising and third-party cookie deprecation forces structural changes in targeting and measurement, Index Exchange's clean supply path positioning and publisher-first approach make it a preferred partner for premium publishers navigating a period of significant disruption. Its independence from major buy-side platforms gives it credibility on both sides of the marketplace.

About

Ankr is a Web3 infrastructure platform offering remote procedure call node access to more than 30 blockchain networks through a globally distributed network of nodes run by independent operators. Unlike centralized providers that operate their own data centers exclusively, Ankr's decentralized architecture routes requests across geographically distributed nodes, improving latency for users in regions underserved by US- or EU-centric infrastructure. Its public free-tier RPC endpoints — available for Ethereum, BNB Chain, Polygon, Avalanche, Fantom, and dozens of others — have made Ankr one of the most widely used infrastructure providers in the multi-chain developer ecosystem.
