Knowledge sharing

We believe that knowledge sharing helps
to connect, perform better, and become stronger.

Making technology accessible

We think that accessible technology is beneficial
from legal and business standpoints, but it also helps
to promote a more inclusive society that benefits all.

Safety and security

We strive to protect people and organisations from harm
caused by synthetics media.

Our Mission

We are a team of young engineers who grew up with all the benefits of the internet. Our generation is more connected, mobile and abled than any generation prior, because of rapid technological advancements of the last decades. Even though we don't know the world any differently, we may not take it for granted.

Synthetic media is threatening the reliability of all digital data and (in)directly sabotages our society and democracy this way. The same technology can facilitate financial harm and disruption to telecommunication. When everything might be fake how would you identify fake content or fraud? With our software, we at DuckDuckGoose, want to realize a digital environment where we can still believe what we perceive.


DuckDuckGoose is a children's game. It is the English name for what we call “zakdoekje leggen” in Dutch. In this game, a group of players sits in a circle, while another player walks around tapping to each player in turn, calling each a "duck" until finally calling one a "goose", which designates the chosen player as the chaser. The player who identified the “goose” must quickly run away and the "goose" must try to tap him or her. The story is that there is a "goose" hidden between the "ducks". But the "goose" looks like one of the "ducks". It is indeed a matter of catching, or detecting, the "goose". At our company DuckDuckGoose, it's not about the children involved in the game as "ducks" or a “goose”, but about deepfakes that hide among authentic audiovisual material and are indistinguishable to humans. The duck test, i.e., if it looks like a duck, swims like a duck, then it probably is a duck, no longer applies in the case of deepfakes. A goose might look exactly like a duck, but we from DuckDuckGoose can tell the difference.
