Ali Parsadoust (commonly known as Ali Parsa, born 24 January 1965 in Rasht) is a British-Iranian healthcare entrepreneur and former investment banker. He is the founder and CEO of digital healthcare company Babylon Health and the co-founder and former CEO of hospital operator Circle Health.
Parsa was born in Rasht, Gilan Province, Iran to middle-class parents. In 1981, he left Iran in the aftermath of the Iranian revolution. After teaching himself O and A-levels, he attended University College London (UCL) where he studied civil and environmental engineering. After completing his bachelor's degree in 1987, he continued at UCL, earning a PhD in engineering physics in 1995. During his studies Parsa co-founded Victoria & Gilan (V&G), a media promotion company for which he won the Royal Award for the Young Entrepreneur of the Year in 1993. Parsa sold V&G in 1995 to join Credit Suisse First Boston as an investment banker where he was hired by Stephen Hester, who later served as CEO of Royal Bank of Scotland. At Credit Suisse he led corporate finance. In 1997, he moved to Merrill Lynch where he spent two years in technology and UK investment banking. Between 1999 and 2001, Parsa continued at Goldman Sachs, where he was executive director of the European technology banking team.
Parsa set up  Circle in 2004 claiming it would become Europe's largest partnership of clinicians, with some £200m of annualised revenue, near 3000 employees and a successful IPO. He stepped down as Chief Executive in December 2012.
Parsa launched Babylon, a mobile healthcare app, in April 2014. Babylon is a subscription health service provider that enables users to have virtual consultations with doctors and health care professionals via text and video messaging through its mobile application.
Parsa is an advocate of more private-sector involvement in the NHS, believing it improves efficiency, profitability and quality of healthcare. He claims that Babylon "is the beginning of the end for the old-fashioned way we use healthcare" and that within a few years computers will perform better than doctors at making diagnoses.
He was named by the Times among the 100 global people to watch in 2012, and by Health Service Journal among the 50 most influential people in UK healthcare. He was the UK Cabinet Office Ambassador for Mutuals.
