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 the funding, the team has expanded to around 40 employees and a bunch of open-source contributors.
