OpenX seeks new CEO after Matt Sattel exit
OpenX has begun a search for a new chief executive after parting ways with Matt Sattel, who had become CEO in February 2026 following the death of longtime CEO John Gentry. Joshua Metzger has been named interim CEO; in a statement he highlighted the company’s 14 consecutive quarters of year-over-year revenue growth and said OpenX has the products and team to continue transforming the supply-side landscape. Sources told Digiday the leadership change may precede potential merger-and-acquisition discussions, and cited similar C-suite overhauls at rival SSPs (including The Trade Desk and Magnite) as part of a broader trend of consolidation and executive turnover in the supply-side/platform space.
