Occupation	Venture capitalist
Employer	Sequoia Capital
Known for	Former senior steward and managing partner of Sequoia Capital

Doug Leone is an Italian-born American venture capitalist who served for decades as a senior leader and managing partner of Sequoia Capital, one of Silicon Valley's most prominent venture capital firms. Born in Genoa, Italy, Leone immigrated to the United States and rose through the ranks of the technology investment world to become one of the most influential figures in venture capital. At Sequoia, he played a central role in shaping the firm's investment strategy and culture over a career spanning multiple decades, during which the firm backed numerous companies that grew into some of the world's most valuable technology enterprises. Leone served as Sequoia's senior steward — the firm's term for its top leadership role — and became known within the partnership for articulating what he described as certain "laws of physics" of venture capital, principles he would occasionally share with colleagues to guide the firm's approach to investing. His tenure at Sequoia coincided with the firm's evolution from a Silicon Valley-focused venture fund into a global investment platform, and his leadership helped define an era in technology investing. Following his time as senior steward, Leone transitioned to a less active role, with new leadership eventually taking the helm at the firm.

Early Life

Doug Leone was born in Genoa, Italy. He later immigrated to the United States, where he pursued his education and eventually built a career in the technology and venture capital industries. Details of his early upbringing in Italy and the circumstances of his family's move to the United States are not extensively documented in public sources. His background as an immigrant who rose to the top of one of Silicon Valley's most elite investment firms has been noted in coverage of his career.

Career

Sequoia Capital

Doug Leone spent the bulk of his professional career at Sequoia Capital, the venture capital firm founded by Don Valentine in 1972. Over the course of his tenure, Leone rose from an investing partner to become one of the firm's most senior leaders, ultimately serving as its managing partner and senior steward — the designation Sequoia uses for its top leadership position.

Sequoia Capital, under the stewardship of leaders including Leone and his longtime colleague Michael Moritz, became one of the most successful venture capital firms in history, investing in a series of companies that went on to achieve massive scale in the technology sector. The firm's portfolio during Leone's active years included investments across enterprise software, consumer internet, financial technology, and cybersecurity, among other sectors.

Leone's role at Sequoia extended beyond individual deal-making to encompass the firm's broader strategy, culture, and institutional direction. He was known within the Sequoia partnership for articulating guiding principles for the firm's investment approach, which he framed as "laws of physics" of venture capital — fundamental truths about how the industry operates that he believed should inform the partnership's decision-making. These principles became part of the internal culture at Sequoia and were referenced by colleagues and observers as illustrative of Leone's management philosophy.

During Leone's tenure, Sequoia expanded its operations significantly beyond its original Silicon Valley base. The firm established investment operations in China, India, Southeast Asia, and other markets, growing from a U.S.-focused venture fund into a global investment platform. This expansion represented a strategic shift that would later become a subject of internal debate within the firm and the broader venture capital industry.

Leadership and the Steward Model

Sequoia Capital employs a distinctive leadership structure in which the firm's senior leader is designated as the "steward" rather than a traditional chief executive or managing partner title. This nomenclature reflects the firm's philosophy that its leaders serve as custodians of the institution rather than as individual power centers. Leone served in this senior steward role for an extended period, during which he was responsible for guiding the partnership's strategic direction and maintaining the firm's competitive position in an increasingly crowded venture capital landscape.

Leone's period as senior steward saw Sequoia navigate several significant transitions in the technology industry, including the rise of cloud computing, the smartphone revolution, the growth of software-as-a-service business models, and the emergence of artificial intelligence as a transformative technology. The firm's investments during this period included companies operating across these themes.

After Leone's active leadership period, Sequoia underwent further leadership transitions. Roelof Botha succeeded as the firm's senior steward, and subsequently, in late 2025, the firm announced another leadership change. Partners Alfred Lin and Pat Grady were put in charge of the firm following an internal vote that resulted in Botha's departure from the top role. The Financial Times reported that partners called a vote to oust Botha after what the publication described as "controversial incidents" that had rocked the firm. Leone, described by this time as the firm's "former senior steward," remained connected to the partnership and its institutional memory even as new leadership took the helm.

Investment Philosophy and Notable Investments

Sequoia Capital's investment approach during Leone's years of leadership was characterized by early-stage bets on companies with the potential for outsized growth, combined with an increasing willingness to invest at later stages as the firm's assets under management grew. The firm's portfolio during this era included companies that became leaders across multiple sectors of the technology industry.

Among the companies in Sequoia's portfolio during Leone's tenure were investments in enterprise technology, financial services, and cybersecurity. Sequoia's investment in Wiz, the cloud security company co-founded by Assaf Rappaport, Yinon Costica, Roy Reznik, and Ami Luttwak, was highlighted by the firm as an example of its approach to identifying and supporting promising founding teams. Sequoia partnered with Wiz in February 2020, and the company subsequently grew rapidly in the cloud security market, eventually attracting acquisition interest from Google.

The firm also backed ServiceNow, the enterprise software company founded by Fred Luddy. ServiceNow's trajectory — from a company started by a founder who reinvented himself at age 50 to a business valued at over $150 billion — was featured as part of Sequoia's "Crucible Moments" podcast series, which highlighted the defining decisions in the histories of the firm's portfolio companies.

Sequoia's investment in Nubank, the Brazilian digital bank founded by David Vélez, represented the firm's expansion into Latin American markets. Nubank grew to become Latin America's most valuable financial services company, a trajectory that the firm also documented through its Crucible Moments series.

Additionally, Sequoia invested in Cresta, an artificial intelligence company focused on contact center transformation. Cresta's CEO, Ping Wu, who previously built Google's contact center business, led the company in developing AI-powered tools to transform customer experience operations.

Relationship with Michael Moritz

Leone's career at Sequoia was closely intertwined with that of Michael Moritz, the Welsh-born venture capitalist who served alongside him as a senior partner at the firm for many years. Together, Leone and Moritz led Sequoia through a period of significant growth and success, and the two were frequently referenced together in accounts of the firm's history and leadership.

Despite their long professional partnership, Leone and Moritz have at times found themselves on opposite sides of public issues. In October 2025, it was reported that the two former Sequoia leaders had donated money to opposing sides of California's Proposition 50, a controversial redistricting measure placed on the ballot by Governor Gavin Newsom. The San Francisco Standard noted that the two men, who had "led Sequoia Capital for decades," were supporting opposite positions on the ballot measure. This divergence illustrated that while the two shared a professional history at Sequoia, they maintained independent perspectives on political and policy matters.

Personal Life

Doug Leone resides in the San Francisco Bay Area, where Sequoia Capital is headquartered. He has been involved in political and civic activities, including financial contributions to political campaigns and ballot measures in California. In 2025, Leone made donations related to California's Proposition 50, a redistricting initiative championed by Governor Gavin Newsom, placing him on the opposite side of the issue from his former Sequoia colleague Michael Moritz.

Leone's Italian origins — he was born in Genoa — have been noted in profiles and coverage of his career, with his immigrant background occasionally highlighted as part of his personal narrative in the context of his rise in Silicon Valley's venture capital community.

Legacy

Doug Leone's legacy is closely tied to the institutional legacy of Sequoia Capital during the period of his leadership. Under his stewardship, alongside that of Michael Moritz and other partners, Sequoia maintained and strengthened its position as one of the preeminent venture capital firms globally. The firm's investment track record during Leone's active years included backing companies that collectively grew to be worth hundreds of billions of dollars in market capitalization.

Leone's articulation of the "laws of physics" of venture capital — the fundamental principles he believed governed the industry — became part of Sequoia's institutional culture and was referenced by subsequent partners and industry observers as emblematic of the firm's disciplined approach to investing. His emphasis on these principles reflected a belief that successful venture investing required adherence to certain enduring truths about markets, founders, and competitive dynamics, even as the specific technologies and companies changed over time.

The leadership transition at Sequoia following Leone's tenure as senior steward has been the subject of significant industry attention. The firm's evolution from Leone's leadership to Roelof Botha's stewardship, and subsequently to the appointment of Alfred Lin and Pat Grady as the firm's new leaders in late 2025, reflected ongoing debates within the firm about strategic direction and institutional governance. Leone's era at the firm is viewed as a period of stability and expansion that set the stage for the subsequent challenges and transitions the firm experienced.

Within the venture capital industry, Leone is recognized as one of the most consequential figures of his generation. His career at Sequoia spanned a period during which the venture capital industry itself underwent dramatic transformation — from a relatively small, clubby corner of the financial world to a global industry managing hundreds of billions of dollars and playing a central role in the development of the technology sector.
