In 2009, Marsh came up with the idea for hospitality business onefinestay. It launched in 2010 and was acquired six years later by AccorHotels for at least $170 million (£117 million).[6] After Marsh left the company in September 2016, he was appointed as a panel member of the 2017 Taylor Review of Modern Working Practices, commissioned by then British Prime Minister Theresa May.[7][8] That year, he joined the faculty at Harvard Business School, teaching entrepreneurship, and was also elected to the International Board of Amnesty International. Marsh is also a visiting professor at Imperial College Business School.[9][10]
In 2021, Marsh co-founded Nous, a money-saving tool which manages households' bills, such as energy, mobile and broadband. In February 2022, the platform announced it had raised £6.6m ($9m) in seed funding.[11][12][13]
Marsh is a household finance commentator who appears regularly on Sky News and LBC, and has contributed to British newspapers and other broadcast media on topics including entrepreneurialism, consumer finance, the cost of living crisis and mental health.[14][15][16][17][18][19][20]
