John Glynn

John W. Glynn Jr. was one of Silicon Valley's pioneering venture capitalists, with a career on Sand Hill Road spanning more than 50 years. Born August 23, 1940, in Kansas, he graduated from the University of Notre Dame (1962), earned his law degree at the University of Virginia School of Law (1965), and completed an MBA at Stanford Graduate School of Business (1970). He was awarded an honorary doctorate from Trinity Washington University in 2022.

He began his venture career in 1970 working alongside Reid Dennis at American Express, where he made an early investment in Intel after meeting co-founders Robert Noyce and Gordon Moore. In 1974 he co-founded Lamoreaux, Glynn & Associates, and in 1983 he established Glynn Capital Management in Menlo Park. Over the decades the firm grew to manage roughly $1.6 billion of public and private technology investments with a small team of about 26 people.

Alongside investing, Glynn was a dedicated educator. Beginning in the late 1980s he taught venture capital and entrepreneurship for more than 25 years at Stanford GSB, at the University of Virginia's Darden School (where he held the Thomas C. MacAvoy Professorship), and at the University of Cambridge's Judge Business School. He was a major philanthropist, endowing the Glynn Family Honors Program at Notre Dame (2006) and the John W. Glynn Jr. Law & Business Program at UVA (2003), and supporting the Focused Ultrasound Foundation.

John Glynn died on July 26, 2023, at Brigham and Women's Hospital in Boston at age 82. He was survived by his wife of 57 years, Barbara, four children, and nine grandchildren. Glynn Capital continues to operate as a technology-focused investment firm following his passing.

• Invested primarily in technology companies at the early-growth and later stages (private Series B/C/D rounds and public tech equities), rather than seed or angel deals.
• Sought founders who could create markets, describing his approach as "mixing art into the science of investing."
• Evaluated CEOs on their ability to delegate, manage and build teams, and execute consistently: *"Making money is a byproduct of executing well on a consistent basis."*
• Emphasized relationship-building and trust over transactional dealmaking: *"Listening is the best way to build a bond of trust."*
• Favored long-term value creation — prioritizing durable free cash flow over short-term metrics, moving quickly on reversible decisions, backing "unlimited upside" ideas, and building reserves during downturns.
• Sector emphasis over time spanned semiconductors, enterprise/B2B software and SaaS, internet and social platforms, fintech, and more recently AI/big data and cybersecurity.
