Fathom showcases the work of approximately 100 artists and volunteers and draws inspiration from other immersive art experiences such as Meow Wolf.

Many of the artworks were previously exhibited at the Portland Winter Light Festival, Burning Man, Symbiosis, and Maker Faire.

[3] Chris Herring noted that the design process was influenced by companies like Meow Wolf, with advice emphasizing the importance of creating art for personal enjoyment rather than targeting specific audiences.

[2] Fathom was created by founding members — Tyler FuQua, Chris Herring, Jason Hutchinson, Kevin Kearns, and Jean Margaret Thomas — who established the limited liability company Roboto Octopodo to manage the installation's production.

[6][7] Fathom is situated in a downtown Portland neighborhood described as struggling, and it has transformed 8,000 square feet of a former drugstore into an immersive oceanic environment.
