DuckDuckGo was solo-founded by Gabriel Weinberg in February 2008 in Valley Forge, PA (USA).
It was self-funded until October 2011, when it was backed by Union Square Ventures and a handful of angel investors. Since that funding, and a second round of funding by OMERS Ventures in 2018, the team has expanded to over 100 employees and a bunch of open-source contributors.
