PopCash

What kind of company is PopCash?

PopCash is a private advertising technology company that operates a self-serve popunder ad network. It connects advertisers buying low-cost pop traffic with publishers monetizing website visitors.

Is PopCash a public company?

No. PopCash is privately held and has never taken institutional funding. It has no stock listing and publishes no financial statements.

Where is PopCash headquartered?

The company is headquartered at Soseaua Fabrica de Glucoza 9B in Sector 2, Bucharest, Romania. It also lists operational presence in Costa Rica and Panama.

How many brands does PopCash own?

The company operates two platforms: PopCash, the original popunder network, and Mondiad, a multiformat ad network launched in 2019.

Who owns PopCash?

PopCash is owned and controlled by its co-founders, known publicly as Alex and Radu, who founded the company in Bucharest in 2012 and have retained ownership since.

How does PopCash make money?

The company earns the spread between what advertisers pay for popunder impressions and what it pays publishers for traffic. Advertisers buy on a CPM basis through a self-serve platform, and publishers are paid daily.

The founders began planning the business in early 2012, spent several months building the platform, and ran first internal tests on September 20, 2012. PopCash launched publicly on October 1, 2012, as a specialized popunder traffic network based in Bucharest.

The company's bet was that popunder ads, which load behind the active browser window, could deliver strong advertiser performance with less user disruption than pop-ups. By narrowing to a single format, the team built targeting, anti-fraud, and optimization systems designed specifically for pop traffic.

The network scaled quickly. By 2015 it was processing more than 500 million unique monthly visitors, ranking it among the most visited ad platforms of its era. Its self-serve structure, low minimum deposits for advertisers, and daily publisher payouts attracted a large base of small and mid-size clients.

In 2019, the team launched Mondiad as a complementary multiformat network, carrying the company's expertise into push, native, banner, and Telegram Mini App ads. PopCash itself stayed focused on popunder inventory. Through the 2020s the company continued operating profitably at small scale, with staff distributed across Romania, Argentina, Bolivia, and other locations, and it marked its 13th year of continuous operation in 2025.

No enforcement actions, lawsuits, or sanctions against PopCash are documented as of November 2026. The company operates in a category that faces generalized criticism: popunder advertising is blocked by default in some browsers and is associated with aggressive affiliate marketing, but PopCash itself has not been named in regulatory proceedings.
