Reuveny was born in Ramat Gan, Israel, lived in Kibbutz Sdot Yam, and lives in Rosh HaAyin, Israel, and is Jewish.[2][1][3][4] He is the son of Dr. Ronen Reuveny, an exercise physiologist, and Kate Reuveny (née Brown), a technical writer.[4] His father was born in Israel, while his mother is originally British and a Jewish convert. He has an older sister, Eden, and two younger brothers, including one who has been serving as a combat soldier in the Israel Defense Forces since the 7 October Hamas-led attack on Israel.[3] Reuveny's parents encouraged him to take up sports from a young age, and as a child he trained in several different sports, including cycling, swimming, tennis, and surfing.[4]
In 2023, he won a bronze medal in a competition as part of the 2023 Sailing World Cup, the Princess Cup, in Palma, Spain.[7]
In the 2024 iQFoil World Championships held in Lanzarote, Spain, Reuveny finished in eighth place.[6] Shortly after the competition, the Executive Committee of the Israel Sailing Association selected Reuveny to represent Israel at the 2024 Summer Olympics.[6] Reuveny was not considered a medal contender by the Israel Olympic Committee. During training, he said: "There are still hostages in Gaza and it was difficult training when the whole country is burning."[3]
You floated on the surface of the water like something divine. You made a whole nation happy, a nation that is at war and a nation that prays for the return of those being held hostage.... our anthem was played, Hatikva, hope, for the first time in these Olympics....[3]
