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
Biconomy is a Web3 infrastructure platform focused on making decentralized applications usable by mainstream audiences who are not familiar with cryptocurrency gas mechanics. Its core product implements account abstraction via ERC-4337, allowing dApp developers to sponsor gas fees on behalf of users, accept gas payment in ERC-20 tokens instead of native currency, and batch multiple on-chain transactions into a single user action. These capabilities transform the user experience from one requiring native token balances and technical awareness into something closer to a conventional web application workflow.
