Sall Grover is an Australian entrepreneur and former Hollywood screenwriter who founded Giggle, a female-only social networking app. Her refusal to admit males who identify as women led to a landmark legal battle — Tickle v Giggle — that has become one of the most closely watched sex-based rights cases in the world.
Giggle for Girls
Giggle is a female-only social networking app founded in 2019 to provide women with a safe online space for connection, support, roommate matching, and freelance networking. The app used facial recognition technology to verify that users were biologically female. After growing to tens of thousands of users across dozens of countries, Giggle became the subject of a landmark Australian federal court case — Tickle v Giggle — when a male user who identifies as a woman had his access revoked and filed a discrimination complaint. The case has become one of the most significant legal battles over the definition of "woman" and the right to operate female-only spaces anywhere in the world.
Biography
Sall Grover is an Australian entrepreneur and former Hollywood screenwriter who spent nearly a decade in Los Angeles before returning home to Australia. Her experiences with sexual harassment in the film industry directly inspired her to build Giggle, a women-only digital space where females could connect safely.
When a male user who identifies as a woman was removed from the app, Grover refused demands to reinstate him, apologize publicly, and undergo "gender education." The resulting legal case, Tickle v Giggle, went to the Federal Court of Australia, which ruled against her in 2024, finding indirect discrimination under the Sex Discrimination Act and ordering her to pay $10,000 in damages plus $400,000 in legal costs.
Grover appealed, arguing that the ruling misinterprets the meaning of "sex" and undermines women's rights to female-only spaces. The appeal was dismissed by the Full Federal Court on May 15, 2026, with an additional finding of direct discrimination and a further $20,000 in damages ordered.
Grover continues to fight, and the case has galvanized women's rights advocates across Australia and internationally around the question of whether biological sex can be legally recognized as a basis for single-sex spaces.
