Zong

Zong was a mobile carrier-billing micropayments company that let consumers buy digital goods, apps, and content and charge them directly to their mobile phone bill, without entering credit-card details. Founded in 2008 (spun out of Echovox) and led by CEO David Marcus, Zong was backed by Matrix Partners and NewMargin Ventures and published a developer API for selling and delivering content to mobile customers worldwide. eBay acquired Zong in 2011 for roughly $240M and folded its technology into PayPal; the brand went offline around May 2015 and zong.com now redirects to PayPal. The company is defunct and operates no live API or developer platform today.

Zong is profiled on the APIs.io network. Tagged areas include Company, Fintech, Payments, Mobile Payments, and Carrier Billing.
