OpenX Software Ltd., known as OpenX,[2] is a programmatic advertising technology company. The company has developed an integrated technology platform that combines ad server and a real-time bidding (RTB) exchange with a standard supply-side platform (SSP) ensuring the highest real-time value for any trade. OpenX was founded in 2008[3] and has raised over $75 million from Accel, Index, Samsung, Dentsu, Mangrove Capital and others.[4]


OpenX has offices in Pasadena (HQ), New York, Tokyo, London, and Kraków.[5]

In September 2017, OpenX acquired two publisher tools, Mezzobit and PubNation.[6]

After laying off "around 100 employees" in December 2018,[7] the following month OpenX announced plans to move all on-premises workloads fully into the Google Cloud Platform by Q2 2019.[citation needed]

In May 2019, OpenX launched OpenAudience, a planning and targeting tool based on LiveRamp and Tapad data.[citation needed]

In January 2020, OpenX announced that CEO and co-founder Tim Cadogan was leaving to become the CEO of GoFundMe and that President John Gentry would step into the CEO role.[8] This was followed in April by another round of layoffs where 15% of the company was affected.[1]
