History
The company was founded on September 4, 2020, by Israeli-born American actress, producer, and director Natalie Portman and French producer and author Sophie Mas.[1][2] The company gets its name from the Sisyphus myth, Portman and Mas' shared interest in mountains, and the "A" from the first letter of all of Portman and Mas' children's names.[3]
In March 2021, the company entered a exclusive multi-year first look television production deal with Apple Inc.[2][4]
