Nitrogen Studios

Cinesite Vancouver is a Canadian animation company founded by husband and wife duo Greg Tiernan and Nicole Stinn. The company was founded in October 2003, in Vancouver, British Columbia.
On March 7, 2017, Nitrogen was acquired by British visual effects and feature animation studio company Cinesite, becoming their Vancouver operations.

Controversy

Several days after the release of Sausage Party, allegations of poor treatment of Nitrogen Studios employees surfaced in the comments section of an interview with Tiernan and co-director Conrad Vernon, featured on the website Cartoon Brew. Various anonymous posters, purporting to be animators who worked on the film in question, made claims including that Nitrogen forced them to work overtime for free and that some employees were threatened with termination. Some animators who complained or left due to stress went uncredited in the film. One poster stated that Tiernan had developed a reputation for "disturbing behaviour and abusive management style". Publications such as the Washington Post the Los Angeles Times and /Film have picked up the story.
