About Me

He resigned as chairman of Workday in 2021; he cofounded the HR and finance software firm in 2005 and took it public in 2012. Duffield cofounded PeopleSoft at age 47 in 1987 and sold it to Oracle for $10.7 billion in cash in 2005. He founded his sixth enterprise software company, Ridgeline, in 2017, and is chairman of the cloud software firm for investment managers. He has spent more than $900 million supporting animal welfare, education and other causes, mostly via his family foundation and Maddie's Fund.
