9GAG

The website was co-founded in 2009–2010 by University of Hong Kong student Ray Chan, his brother Chris Chan, and others, with the intention of creating an alternative online platform to email on which users could easily share humorous photos or videos. In a 2012 interview, Ray Chan declined to explain where the name "9GAG" is derived from.

Starting the company under a “Just for Fun” mentality, 9GAG's co-founders began using 9GAG as a résumé-builder for the 500 Startups accelerator program. During the summer program, the 9GAG team worked on other startup ideas, including StartupQuote and Songboard.

Following the 500 Startups accelerator program, 9GAG participated in Y Combinator's incubator and its user-base increased to 70 million global unique visitors per month.

The 9GAG co-founding team discontinued all other projects and shifted their focus exclusively on 9GAG. 500 Startups was given equity for their aid and mentorship.

In July 2012, 9GAG raised an additional US$2.8 million in funding from Silicon Valley-based venture capital,

including True Ventures and Greycroft Partners. In August 2012, 9GAG received another US$2.8 million in funding from Silicon Valley venture capitalists, including True Ventures and Greycroft Partners, as well as individual investors like Christopher Sacca, Kevin Rose, and Naval Ravikant. This funding was able to support 9GAG's engineering team growth both in Hong Kong and in Silicon Valley.

Mobile app development

9GAG has a mobile application on iOS, Android, Windows Phone 8, and BlackBerry 10.

In July 2012, 9GAG launched an app for iOS and Android. The mobile application serves as a streamlined version of the web-based content.
