PubMatic is a company which develops and implements online advertising software and strategies for the publishing industry. PubMatic's advertising software puts publishers of websites, videos and mobile apps into contact with ad buyers by using automated systems, while allowing users to opt-out of having their personal information collected on internet searches. PubMatic has a number of offices in countries around the world. 
PubMatic, for a fee, participates in online auctions to buy and sell media and advertising spots between various advertising companies.  The company also produces quarterly reports about advertising prices.
By 2016 the firm was operating by storing most of its data on OpenStack private cloud servers.
