MediaMath Files For Bankruptcy, Owes Hundreds Of Millions

Demand-side platform MediaMath filed for Chapter 11 bankruptcy protection in Delaware district court on Friday. The company owes between $100 million and $500 million to between 200 and 999 companies, including Google, Magnite, OpenX, PubMatic, Xandr, among many others.

Emails went out to MediaMath employees and partners on Friday to say the company will shut down operations in the coming months, according to initial reports.

The top five include Magnite at nearly $12.6 million, PubMatic at nearly $10.5 million, Sonobi at $5.3 million, Xandr at $4 million, and AdsWizz at 3.4 million.
