Automattic

Global leader in open-source CMS and hosted website publishing, powering over 40% of the web through WordPress and related products

Automattic is a web technology company best known for operating WordPress.com, the hosted version of the world's most popular content management system, which powers over 40% of all websites on the internet. Founded in 2005 by Matt Mullenweg (co-creator of WordPress), the company operates as a fully distributed, remote-first organization with employees across more than 90 countries. Beyond WordPress.com, Automattic's portfolio includes WooCommerce (e-commerce), Jetpack (site performance and security), Tumblr (social blogging), Akismet (spam filtering), Simplenote, Day One, and Pocket Casts. In the AdTech and publisher ecosystem, Automattic plays a significant role through WordAds — its advertising network for WordPress.com publishers — and through its integration with major ad networks and monetization tools. The company enables content creators, bloggers, small businesses, and enterprise publishers to build, manage, and monetize digital properties at scale. Its acquisition of Tumblr in 2019 and continued investment in open-source infrastructure underscore its commitment to an open, independent web. Automattic occupies a unique position in the market as both a platform provider and an ecosystem enabler, competing with hosted CMS platforms like Squarespace and Wix while also powering a vast network of independent publishers. With a valuation reported at approximately $7.5 billion following a 2021 funding round, Automattic is one of the most significant private technology companies in the content and publishing space, with deep relevance to digital advertising through its massive publisher reach.
