About C1X

C1X, an acronym for Class One Exchange, is a digital advertising and marketing technology firm founded in 2014 by a team of former Yahoo employees including Mukundu Kumaran (CEO), Daisuke Daniel Nagayama (COO and Chief Global Strategist), and Rajkumar Madhuram (CTO).

The platform provides an integrated suite of tools that allows advertisers to precisely target and purchase desired audiences across video, mobile, display, and native ad formats. For publishers, C1X offers a yield maximization solution to enhance monetization. A key feature is its advanced header tag solution, which supports the latest in header bidding technology and proprietary transaction methods. This enables buyers to acquire specific audiences on premium websites with data-backed guarantees.

C1X also caters specifically to the eCommerce sector with a fully automated native ad server suite. This functionality allows online marketplace operators to generate new advertising revenue streams, while merchants can boost their sales through data-driven product promotions. The company is headquartered in Santa Clara, California, with a significant engineering and development hub in Chennai, India, and has established a presence in major global markets.
