At Microsoft, Risher was General Manager in charge of launching the company's first database product,
Access. He went on to found and manage Microsoft Investor. In 1997, he left Microsoft over
Bill Gates' objections to join
Amazon.com as its first Vice President of Product and Store development. He later served as the company's Senior Vice President, US Retail, leading the marketing and expanding into new categories to grow Amazon's retail sales from $15 million to $4 billion. As a tribute to Risher's leadership,
Jeff Bezos created a hidden perpetual "easter egg" on the Amazon website when he left the company. After leaving Amazon in 2002, Risher taught at the
University of Washington's
Foster Business School, where he created the University's course on “Competing on the Internet.” He was elected Professor of the Year in 2004. Risher co-founded
Worldreader after a year-long, 19-country trip around the world with his family, road-schooling his daughters and volunteering. After visiting an orphanage in
Ecuador, Risher saw how technology could help traditionally underserved children read. Worldreader is a US-based
501(c)(3) with an additional registration in Kenya. Worldreader believes that “readers build a better world" and uses digital technology to get families with young children reading so they can reach their potential. In March 2010, Worldreader launched a trial in Ayenyah, Ghana. Worldreader reports that, after receiving positive results, they were granted permission from Ghana's Ministry of Education to distribute e-readers to additional schools in Ghana. Since then, the organization has helped over 20 million readers in the United States and globally across more than 100 countries. Worldreader's BookSmart reading app offers children books and learning activities in six languages. Risher joined the board of
Lyft in July 2021 and was appointed chief executive officer in April 2023. His approach has been to use customer obsession to drive profitable growth. Lyft has achieved profitability, authorized its first share-repurchase program (US$750 million), and acquired the European mobility app
FREENOW as part of an effort to expand internationally and nearly double its addressable market. Risher has said that Lyft aims to move away from reliance on surge-pricing (“Prime Time”) by increasing driver supply, improving service metrics, and expanding fixed-price options such as Price Lock, calling
surge pricing “deeply unpopular” with riders. He has also discussed the company’s approach to autonomous vehicles, describing a hybrid network that combines human drivers and robotaxis rather than a full transition to driverless fleets. Risher is
Schwab Foundation Social Entrepreneur of the year, a Microsoft Alumni Foundation Integral Fellow, and Draper Richards Kaplan Foundation Social Entrepreneur. He serves on the board of directors of
Lyft, Inc and has served on the International Advisory Board of
ESADE, and International Advisory Board of Catalunya. == Philanthropy ==
