At the age of 14 he won the silver medal in the Archimedes math contest of the Greek Mathematical Association. He then received a scholarship to attend the Phillips Academy in Andover, Massachusetts, US,[4] and he later graduated with a B.A. in International Relations from the University of Pennsylvania,[4][5][6] and a B.Sc in finance from the Wharton School of the same institution.[4][5] While he was a student he volunteered for Joe Biden's campaign during the 2008 Democratic Party presidential primaries.[1]

In 2009 he worked at the back-office "risk management department" of Goldman Sachs.[6][7] He also worked at the think tank of the Center for Strategic and International Studies in Washington, D.C. and later founded Swift Bulk shipping company.[6][8]

He was registered in the electoral rolls of New York as a Republican from 2013 until 2019.[9] On 29 August 2023 Kasselakis declared his candidacy for president of Syriza.[10] In the first round of party elections on 17 September, he finished in first place among five candidates while securing 45% of the vote.[11]

On 24 September 2023 he was elected president of Syriza, winning the second round with 56% of the vote over his opponent, Effie Achtsioglou, who received 44%.[2] After winning the leadership election, Kasselakis said that he wanted Syriza to emulate the U.S. Democratic Party and move to the centre left.[12]

Kasselakis is gay[1][13] and has been in a civil partnership with Tyler McBeth, an American, since 2019.
