Sasha Haco

Sasha Haco (born 1992 or 1993)^[1] is an English theoretical physicist, entrepreneur and chief executive officer of Unitary, an online content moderation company.

Haco received her PhD in Theoretical Physics from the University of Cambridge in 2019.^[2] During her time at Cambridge, she worked with Stephen Hawking, Malcolm Perry and Andrew Strominger on the black hole information paradox. She spent a year as a visiting fellow at Cambridge from 2017 to 2018 and also spent a year at Harvard. In 2020, Haco was heavily featured in the Netflix documentary Black Holes: The Edge of All We Know, which chronicled the use of the Event Horizon Telescope to take the first photograph of a black hole, as well as the work of Haco, Hawking, Perry and Strominger as they attempted to better understand the black hole information paradox.^[3][4]

Haco founded Ditto Software in 2018 and most recently co-founded Unitary, where she currently serves as the chief executive officer.^[5] Unitary works to develop tools to identify and moderate abusive online content.^[6] In 2021, Haco was honoured with the Women in Innovation award recognizing her efforts addressing challenges in society.^[7]
