Who Owns PopCash?

Planning for PopCash began in early 2012, when co-founders Alex and Radu began outlining a specialized popunder traffic network after several months of preparation. The first internal tests ran on September 20, 2012, and version one of the platform launched publicly on October 1, 2012.

The product thesis was simple: popunder ads, which load behind the active browser window, deliver advertiser results without the disruption of traditional pop-ups. PopCash focused exclusively on that single format rather than building a multiformat network, which let it build targeting, fraud filtering, and optimization tools specifically for pop traffic.

Growth was fast. By 2015 the network was serving more than 500 million unique monthly visitors and had become one of the most visited ad platforms on the web. The self-serve model let publishers of any size monetize traffic and let advertisers buy targeted impressions by country and category on a CPM basis.

In 2019 the same core team launched Mondiad, a broader multiformat ad network supporting push, in-page push, native, banner, and other formats. PopCash remained focused on popunder inventory while Mondiad carried the team's expansion into wider adtech. Through the early 2020s PopCash continued operating as a profitable niche network with a compact team distributed across Romania, Argentina, Bolivia, and other locations.

As of 2026 the platform still operates as a self-serve popunder exchange with daily payout processing for publishers and a low minimum deposit for advertisers, maintaining its position among the longest-running dedicated popunder networks.
