Decide
Decide is a St. Louis-based advertising technology company - the rebrand of LockerDome, founded in 2008 - that runs a machine-learning platform called the Decision Marketplace. Rather than relying on third-party cookies or intrusive identity data, Decide lets multiple ML models compete in real time to select and price ad impressions, powering a two-sided marketplace that connects publishers and brands across the open web. Its widgets and content-recommendation units have reached over 100 million monthly users, positioning the company as a cookieless, performance-focused alternative to legacy programmatic ad stacks.
Picnic
Picnic is a London-born ad-tech company building user-first advertising for the open web. It packages social-media-style ad formats - Stories, swipe-to-act, emoji reactions - and delivers them on premium publisher inventory, aiming to make ads people actually engage with rather than ignore. Founded in 2017 by Matthew Goldhill, Picnic pairs its creative formats with PIQ, an inventory-quality platform, and ships every campaign carbon neutral, claiming roughly 50% lower emissions than the industry standard.
Mozilla
Mozilla builds Firefox and a family of privacy-first internet products with a single, stubborn goal: keep the web open, private, and not owned by anyone. Spun out of Netscape in 1998 and run by a for-profit corporation wholly owned by the non-profit Mozilla Foundation, Mozilla competes with the largest companies on earth while answering to a mission instead of shareholders.
Quantcast
Quantcast is a San Francisco-based advertising technology company that uses AI and machine learning to help marketers, agencies and publishers plan, buy, optimize and measure campaigns across the open internet. Built around its patented Ara AI engine and a live Audience Graph that processes trillions of signals a day, Quantcast positions itself as a next-generation demand-side platform for a privacy-first, increasingly cookieless web.
