DuckDuckGo is an Internet search engine founded by programmer Gabriel Weinberg in February 2008 and officially launched on September 25, 2008. On December 1, 2011, the company relocated from Weinberg's basement to its current headquarters in Paoli, Pennsylvania. The alternative search engine grew from one million to ten million searches per day from February 2012 to June 2015.
After selling his technology company, Weinberg began DuckDuckGo in his basement. Having secured an additional $3 million from a third-party investor in 2011, he relocated the company to its current physical location and added additional staff. In May 2012, the company reported a $115,000 profit. As of September 2015, the company has grown its base of employees from two to 23.
As the search engine has gained popularity, some major computing software companies, such as some Apple operating systems and the desktop environment system GNOME, include DuckDuckGo as their default search engine.
DuckDuckGo's primary aim is to provide accurate search results to users while simultaneously preserving privacy. Unlike major search engines such as Google or Bing, DuckDuckGo Does not collect or share search information entered into the search engine. The company also prides itself on producing the same search results to each user; it does not filter results or show ads according to information gathered by the search engine during previous searches.
The search engine is programmed using Perl software and runs on web servers nginx, FreeBSD and Linux.
