DuckDuckGo is built primarily upon search APIs from various vendors. The search engine is written in Perl and runs on nginx, FreeBSD, and Linux. DuckDuckGo gains revenue via advertisements and affiliate programs. Initially self-funded by Weinberg until October 2011, it was then 'backed by Union Square Ventures and a handful of angel investors.' Union Square partner Brad Burnham stated, 'We invested in DuckDuckGo because we became convinced that it was not only possible to change the basis of competition in search, it was time to do it.' In addition, Trisquel, Linux Mint, and the Midori web browser switched to use DuckDuckGo as their default search engine.

Weinberg is an entrepreneur who previously launched Names Database, a now-defunct social network.
