How Don Valentine built Sequoia Capital and modern venture capital

Executive overview

Before Sequoia, Silicon Valley's earliest startups could barely get funded — the eight best engineers in the world had to sell their company to an East Coast instrument maker just to get off the ground. Don Valentine changed that. A marketing executive from Fairchild and National Semiconductor, he combined deep market knowledge, a semiconductor-era network, and Capital Group's capital to create the first firm that treated early-stage investing as company building, not speculation.

The core insight: backing big markets — not pedigree, not founders — and staying in long enough for the real value to compound.

Don Valentine's origin and philosophy

• Grew up in Yonkers to uneducated parents; Jesuit education instilled disciplined questioning
• Built sales at Fairchild from a few million to $150M+ in revenue; developed a process for evaluating which customer markets to pursue — functionally identical to writing an investment memo
• Saw the board reject his idea of investing in ecosystem companies; started doing it personally
• Joined Capital Group in 1972 to do this full-time; named the initial fund "Sequoia Fund"
• Spent three years raising the first independent Sequoia Capital fund (~$3–5M), rejected by Solomon Brothers for not having an MBA
• Founding investment criteria: very large market, Northern California, advanced technology, high gross margins, potential for Sequoia alone to return $100M

The Socratic method and founder assessment

• Used questions of 20 words or fewer; listened for how founders think, not just what they answer
• Assessed storytelling clarity: the ability to explain market size, technical risk, and customer in simple terms signalled execution ability
• Key diagnostic: self-awareness of what founders are good at and what they need help with
• Said: "Give me a giant market always" — willing to replace or augment weak management if the market was right
• Criterion six: founders must be receptive to active Sequoia participation

Early investments and costly lessons

• 1975: Atari — $600K in, sold for ~$6M (4x); missed the 10x boom that came after Warner acquired the company
• 1977: Apple — $150K invested alongside Venrock and Arthur Rock; Mike Markkula (a Don recruit) became chairman
• 1979: Sold Sequoia's Apple stake for $6M pre-IPO to make a tax distribution to LPs — leaving hundreds of billions on the table
• Lesson: structured all subsequent funds with tax-exempt LPs (university endowments, foundations) to avoid forced early exits
• Lesson: let winners run; value in truly great companies compounds for decades

The aircraft carrier strategy

• Recognised Apple would create an entire ecosystem of enabling companies
• Invested in ~15 companies in the PC supply chain: Tandon (disk drives, $1.5B market cap), Printronics (printers), Priam, Dyson
• 1981: LSI Logic — went public two years later in the largest NASDAQ IPO at that time ($153M raised)
• 1982: Electronic Arts, 3Com (out of Xerox PARC)
• 1983: Oracle (six years after bootstrap, rare early software bet), Cypress Semiconductor
• 1987: Cisco — $2.5M for 30% of the company; Don stayed on the board, held shares through the internet era, and made enormous returns — this became the definitive Sequoia playbook

Building the firm and generational transfer

• Added partners with operator backgrounds, not MBAs: Pierre Lamond (Fairchild chip designer, joined 1981, still active at 89)
• 1986: Michael Moritz joined — a British journalist at Time Magazine who had written a book on Apple; Don saw his journalist instinct as the perfect analytical disposition
• Late 1980s: Doug Leone cold-called Don from HP and was hired; now runs Sequoia's global operations
• Funds grew steadily to ~$150M per fund by the 1990s
• 1996: Don called Mike and Doug into a room and handed them the firm outright — no conditions on keeping him involved, decisions entirely theirs
• Sequoia positioned itself to LPs on two things: superior returns and generational stability

The Sequoia playbook distilled

• Focus on the size and adoption dynamics of the market, not the founder's background
• Change equals opportunity: invest in the confusion phase, before a big market becomes obvious
• Augment or replace teams as needed; be a company builder, not a capital allocator
• Only invest in founders receptive to your active involvement
• Let winners run — the majority of value in great companies accrues years or decades after investment
• Use only patient, tax-exempt LP capital so you're never forced to exit early
• Transfer firm leadership before you're the constraint on its growth
