URX

URX, founded in 2012 by John Milinovich, Andrew Look, James Turner, and Nathanael Smith, operated as a mobile advertising technology company from its headquarters in San Francisco. The company emerged from the Y Combinator accelerator program in the summer of 2013. URX's core business was centered on enhancing mobile content monetization for publishers and driving mobile commerce for advertisers. It developed a platform that utilized deep linking technology, which allows users to be directed to specific content within a mobile application rather than a generic landing page or app store.

The company's flagship product, Omnilinks, functioned as a smart deep link capable of routing users to a specific page inside an app if they had it installed, or to a corresponding webpage if they did not. This addressed a significant friction point in the mobile user experience, where links often failed to connect seamlessly between web and app environments. URX's business model evolved to function as an ad network; it purchased advertising space within mobile apps and resold it to advertisers, including prominent clients like HotelTonight and Spotify. This model was initially validated through a mobile retargeting solution that attracted clients such as Airbnb and LivingSocial, leading to a successful seed funding round.

Financially, URX secured a total of $15.1 million in funding over three rounds. This included a $3.1 million seed round in 2013 with participation from notable investors like First Round Capital, Google Ventures, and SV Angel. A subsequent Series A round in April 2014, led by Accel Partners, raised an additional $12 million. The company's journey culminated in May 2016, when it was acqui-hired by Pinterest. The deal was primarily for URX's talent, with Pinterest absorbing about half of the team to bolster its own efforts in content understanding, recommendations, and discovery. Following the acquisition, the URX advertising product was shut down, and co-founder John Milinovich transitioned to a product manager role at Pinterest.
