David Duffield

David Arthur Duffield (born 21 September 1940) is an American billionaire businessman in the software industry.

He is the co-founder and former chairman of PeopleSoft, co-founder and CEO emeritus of Workday, Inc., and current founder and co-CEO of Ridgeline, Inc. He has been on the Forbes World's Richest People list for many years.

Duffield co-founded two publicly traded enterprise software companies after age 40: PeopleSoft and Workday.

He has given $303 million to companion animal welfare causes and organizations; $61 million to his alma mater Cornell University; over $100 million to expand other educational institutions close to him and his family; $13 million to local first responders and community organizations; and $2.1 million to veterans affairs.

His current philanthropic interests are managed by the Dave & Cheryl Duffield Foundation.

Their capstone project is Liberty Dogs, a service dog training campus in Reno, Nevada, that will match and train disabled military veterans and canine companions.

This facility is planned to open in 2026.

Raised in Ho-Ho-Kus, New Jersey, Duffield graduated in 1958 from Ridgewood High School in nearby Ridgewood, where he was co-captain of the baseball team.

Duffield received a bachelor's degree in electrical engineering and an MBA from Cornell University, and is the benefactor behind Cornell's Duffield Hall, a nanoscale science (or nanotechnology) and engineering facility at Cornell.

While at Cornell, Duffield was a member of Beta Theta Pi.

In 1964, Duffield began his career as a marketing representative and systems engineer at IBM.

He left IBM to found Information Associates, which developed university exam scheduling software.

In 1972, he left to start Integral Systems, which eventually became the top higher education human resources management system vendor.

In 1979, he moved on to start Business Software Corporation, which provided real-time human resources and payroll applications for commercial enterprises.

Duffield founded PeopleSoft in 1987 and served as the company's CEO and board chairman.

In 1994, Duffield and his wife Cheryl established Maddie's Fund, to bring change, collaboration, and innovation to the animal welfare industry.

This organization is named after the Duffields’ Miniature Schnauzer who was a "lighthouse during the stormy period" of the couple's work careers.

Maddie died of cancer in 1997, and Duffield acted on his earlier promise to his pet: "If we ever make some money, I promise we will give it back to you and your kind so others can be as happy as we are today."

The Duffields have endowed Maddie's Fund with more than $345 million; the organization has spent in excess of $275 million through FY2022-23.

In January 1997, they donated $20 million in support of interdisciplinary engineering and scientific research and education.

The new Engineering building was later renamed “Duffield Hall.”

PeopleSoft grew to be the world's second-largest application software company before being acquired by Oracle in January 2005 for $10.7 billion cash.

In March 2005, Duffield and former PeopleSoft vice chair and head of product strategy Aneel Bhusri started Workday, Inc., a company that provides financial management, human capital management, and planning software delivered in the form of a software as a service (SaaS) model.

The company is headquartered in Pleasanton, California, and employs more than 17,500 people today.

Duffield was known as the company's chief customer and employee advocate.

He relinquished the co-CEO role in May 2014 and became chairman of the board.

He resigned as chairman in April 2021 and was appointed chairman emeritus and ultimately CEO emeritus by Workday’s board.

The Duffields established the Dave & Cheryl Duffield Foundation (DCDF) in 2016 to continue innovative grant making in animal welfare and support for disabled military veterans.

Based in Incline Village, Nevada, the foundation has supported animal welfare agencies, pet shelters, local schools, and regional community organizations including local parks and the North Lake Tahoe Boys and Girls Club.

Duffield founded his sixth and current company, Ridgeline, in 2017.

Headquartered in Incline Village, Nevada, Ridgeline is an industry cloud software platform for investment management.

The early-stage company currently employs approximately 400 people in offices in Incline Village, Reno, New York City, and San Ramon, California.

In April 2020, the DCDF made a $350,000 grant to Incline Village Community Hospital to address the COVID-19 pandemic.

In response to the 2021 Lake Tahoe forest fires, the foundation donated $4 million to over 30 charities, including $2 million to the Red Cross.

Additionally, DCDF pledged $10.6 million to schools serving Hohokus, New Jersey, where he grew up.

The Dave & Cheryl Duffield Foundation is currently financing the construction and development of Liberty Dogs in Reno, Nevada.

This campus is planned to open in 2026.

The goal is to provide disabled veterans with the ability to lead more independent and fulfilling lives through the enhanced emotional and psychological well-being that research shows a Liberty Service Dog provides.

Most recently, DCDF pledged $2 million to Maui Humane for fire relief efforts.

The Duffields have pledged more than $68 million to Dave's alma mater, Cornell University.
