Sasha Haco is the CEO and co-founder of Unitary, which aims to make the internet safer by automatically detecting harmful online content. Before co-founding Unitary, Sasha was using physics to solve the mysteries of the universe. During her PhD at Cambridge she worked with Stephen Hawking on the black hole information paradox, and spent a year as a visiting fellow at Harvard. Her research, which aimed to derive the entropy of black holes, was documented in the Netflix film The Edge of All We Know. Driven by understanding––and solving––complex problems, Sasha joined Entrepreneur First in 2019 where she met co-founder James Thewlis and founded Unitary in June of that year.
