Douglas M. Leone (born July 4, 1957) is an American billionaire venture capitalist who served as the global managing partner of Sequoia Capital from 2012 to 2022. He is recognized for his decades-long career in technology investing, including leadership in Sequoia's expansion into international markets and its investments in prominent software and Artificial intelligence companies. As of May 2026, his net worth was estimated at US$12.2 billion.
Leone's investment activities in the 2020s have increasingly emphasized Generative AI and related fields, reflecting a broader shift in venture capital toward Machine learning and Large language model startups. He has been a board member for several AI-focused companies, including Cresta, ActionIQ, Cyera, and Wiz, alongside other technology firms.
Early life and education
Douglas Leone was born in Genoa, Italy, on July 4, 1957. His family relocated to the United States when he was 11 years old, settling in Mount Vernon, New York. He completed his undergraduate studies at Cornell University in 1979, earning a bachelor's degree in mechanical engineering. Later, he pursued graduate education in engineering and management: he received a master's degree in industrial engineering from Columbia University's School of Engineering and Applied Science in 1986fake, and a master's in management from the MIT Sloan School of Management in 1988 as a Sloan Fellow.
Career at Sequoia Capital
Leone began his professional career in sales and management roles at technology companies including Sun Microsystems, Hewlett-Packard, and Prime Computer. He joined Sequoia Capital in 1988, became a managing partner in 1996, and assumed the role of global managing partner in 2012. Under his leadership, Sequoia expanded its operations into China and India, establishing a global footprint that became a hallmark of the firm.
His investment portfolio at Sequoia includes notable companies such as Aruba Networks, Hyperion/Arbor Software, International Network Services, Medallia, Netezza, PlanGrid, Rackspace, RingCentral, and ServiceNow. These investments spanned enterprise software, networking, and cloud infrastructure, contributing to Sequoia's reputation as a leading venture firm. In 2017, Forbes named him a top-10 investor in the technology industry in the United States.
In April 2022, Sequoia announced that Roelof Botha would succeed Leone as the senior steward of global brand and operations, effective July 5 of that year, shortly after Leone's 65th birthday. Leone continued as a general partner in Sequoia's existing funds, maintaining his involvement in the firm's investment activities.
AI investments and board roles
In recent years, Leone has focused on investments in Artificial intelligence and Machine learning companies, aligning with the rising prominence of Generative AI technologies. He serves on the boards of several such firms, including Cresta, which applies AI to customer service and contact centers; ActionIQ, a customer data platform using AI; Cyera, a cloud security company leveraging AI; Island, an enterprise browser company; Nubank, a digital bank; strongDM, an access management platform; Trade Republic, a German neobroker; and Wiz, a cloud security startup.
Leone's interest in AI is part of a broader trend among venture capitalists who have backed startups developing Deep learning models, Neural network architectures, and Transformer (architecture)-based systems. Sequoia's portfolio in this area includes investments in companies like OpenAI and Anthropic, which have driven significant advances in Large language model technology, though Leone's specific direct involvement in these deals is not always publicly detailed.
Political engagement and public positions
Leone has been politically active, supporting candidates and causes in the United States. He and his wife donated $100,000 to President Donald Trump's 2020 re-election campaign, and Leone was appointed to Trump's task force on re-opening the economy during the COVID-19 pandemic. The Washington Post reported that Leone proposed using his connections in the Trump administration to facilitate the sale of TikTok, a company in which Sequoia had invested heavily, to a US corporation. Following the storming of the United States Capitol on January 6, 2021, Leone renounced his support for Trump. He later backed America PAC, which supported Trump's 2024 presidential campaign.
Personal life
Leone is married to Patricia Perkins-Leone, and the couple has four children. They reside in Atherton, California. The family has sought to build an oceanfront home in Makena, Maui, Hawaii, but as of November 2017, the Hawaii Supreme Court ruled against the development. In May 2021, Leone was conferred the Order of the Star of Italy, in the class of Officer (Ufficiale dell'Ordine della Stella d'Italia), recognizing his contributions and ties to his country of birth.
