Key Discussion Points & Insights

The Enduring DNA of Greylock (01:32–06:37)

• History and Origins: Greylock started in 1965, pioneering the venture partnership model. Originally an East Coast firm, it migrated to the Bay Area in the 2000s and has outlasted most peers by persistently adapting and reinventing itself.
• Navigating Sectors: Early investments ranged from Continental Cablevision (infrastructure, later part of AT&T/Comcast) to Neutrogena, followed by a major focus on biotech (Millennium, Vertex, Stryker), then open source (Red Hat), social and enterprise (Facebook, LinkedIn, Airbnb, Palo Alto Networks).
• Ethos: The foundational "service mindset" remains. Sam shares:

  “The ambition of every Greylock partner should be to win the Oscar for best supporting actor to the entrepreneur.” (05:02)

Reinvention and Consistency (04:35–06:37)

• Balancing Tradition & Change: Core values (people, service, partnership) persist, but the firm continually reinvents sectors, processes, and speed.
• Low-Profile Ethic: Greylock maintains a quiet, “not loud” posture in press/branding even as the industry has shifted to louder marketing (cf. Andreessen Horowitz).
• Modern Dilemma: Navigating competitive visibility versus foundational ethos—a tension the partnership regularly debates.

Talent, Apprenticeship & the Partnership Model (07:05–13:16)

• Apprenticeship Model: Greylock emphasizes “deep and intricate” development—Saam describes joining at 23, shadowing partners, joining boards, and immersive real-life learning.
• Collective Success Over Sourcing: Credit is given for being “causally impactful” rather than just sourcing deals—encouraging collaborative rather than competitive incentives.
• Hand-Off & Growth: Senior partners intentionally sponsor and elevate younger partners, regardless of tenure difference.

The Flywheel of Relationships & Network (11:52–16:29)

• Brand, Network, & Persistence: Greylock’s credibility compounds—backing a company creates a flywheel that rewards both the firm and future entrepreneurs through trust and network effects.
• Anecdote: The circuitous journey from recruiting Josh McFarland to spinning out engineers and eventually funding new companies like Abnormal AI and Cogent shows how deep relationships drive repeat success.
• Board/Intimate Relationships: True flywheel success requires deep, not arms-length, engagement.

Inputs-Driven Performance Management (29:05–33:58)

• Long-Term View: Performance is measured by “inputs” (actions that should, over time, drive great outcomes) rather than just luck or short-term wins.
• Inputs Document:
  • “See” (90%+ of desired dealflow in a sector)
  • Responsiveness/service level
  • Domain leadership (sector reviews, predictions)
  • Contribution to overall firm success
• No Outputs Without Inputs: Luck alone isn’t rewarded; the system is designed for repeatable greatness.

Incubations, 'Initiations,' and Market/Execution Risk (33:58–43:30)

• Not “Incubations”—Initiations: Greylock prefers partnering with founders as early as possible, ideally before the idea forms, but always putting the founder’s vision first.
• Focus on Market Risk:

  “We want zero market risk and a lot of execution risk”—meaning the demand is validated, but solution is hard to build.

• Common Pitfalls for VCs: Taking too much equity or picking undifferentiated ideas undermines long-term success and founder quality.

Breadth vs. Depth in Venture (24:44–29:05)

• Balance: Depth (intimate involvement, small team, concentrated relationships) is Greylock’s core, but exposure to the market and competitive deal-tracking is critical ("Did we see 75% of competitor financings in our sectors?").
• Avoiding FOMO:

  “Having real clarity in what you’re looking for and then the ability to process and make decisions very quickly.” (27:41)

• Investment Criteria: Process and invest rapidly when the right people and markets surface, rather than through exhaustive memo-writing or midwit rigor.

Venture Alpha: Maker vs. Taker, the Barbell, and “The River” (43:50–59:18)

• Barbell Strategy: Alpha accrues at the “first money” (raw initiations, formative) and “last money” (giant private rounds, market-making) ends. The middle—market-taker/index strategies—is more commoditized and less impactful.
• The Capital River (55:52): Companies that get into the “capital river” (continuous access to top-tier fundraising and adoption flywheel) build compounding advantage.
• Kingmaker Rounds: Doing the round that “puts a company in the river” can create some alpha, but the barbell (raw or late stage) is more distinctive.

Patterns, Persistence, and Decay in Venture Brands (48:54–52:38)

• Venture Brand Endurance:

  “It takes a long time to kill a venture brand… but the default trend line is decay… Most people, when successful, aren’t willing to reinvent themselves.” (49:07)

• Greylock’s Strategy: Proactively empowering young talent, biasing toward action and reinvention (e.g., moving HQ to SF, speeding decisions, young partner cohort).

Portfolio Services: Impact over Marketing (52:38–59:18)

• Services as Value, Not Marketing:
  • “Specialist” teams are first-class citizens, impact is measured (e.g., engineers placed), and integrated into the firm's decision-making.
  • Focused on early-stage support—helping portfolio “get into the river.”
  • Analogy:

    “We’re an Ironman suit—the founder plugs in early; later they build their own machinery.” (55:14)

• Most Portfolio Services Fail: Service for marketing/optics rarely work; true value is in hands-on, early-stage intervention.

Macro Trends: Revenue Ramps, Vertical vs. Horizontal AI (59:18–71:33)

• “River” Company Outcomes: Easier early capital helps, but ultimate outcomes depend on durability of growth and differentiation.
• Caveats from 2021: Explosive early growth doesn’t always endure—pull-forward demand and monetization model errors are common.
• Vertical vs. Horizontal AI: History favors horizontal winners (Salesforce, Microsoft, Workday); AI may disrupt underlying data models and workflow conventions, opening new horizontal opportunities.
  • Ashim’s Trilemma: New pricing, unit of value, and data model in AI era could finally make new giant horizontal software possible.

Personal Life, Friendship, and Partnership (71:33–76:29)

• Venture Friendship: Unlike many performative or opportunistic industry friendships, Jack and Sam’s group fosters high context, mutual ambition-pushing, and real support.

  “It’s rare to have people who have high context for your work but also truly want to see you win.” (72:20)

• Joy in Work: Humor, personal connection, and fun are essential to sustaining ambitious work.

Health & Routine (76:29–79:42)

• Focus: Whole foods, daily movement, sleep, and, crucially, unscheduled time for deep work and strategy.
• Avoiding Burnout: Structured calendars, intentional “no’s,” and maintaining room for serendipity.

Notable Quotes & Memorable Moments

• “The ambition...should be to win the Oscar for best supporting actor to the entrepreneur.” (Saam Motamedi, 05:02)
• "If you're in the carry business, then the only way you do well is if your entrepreneurs do well." (17:53)
• “There’s a flywheel...18 years later, people coming back to start new companies just because of the relationship we built with one person.” (15:00)
• "Depth and intimacy are profound...we care a lot about the people we go into business with." (42:52)
• "We measure inputs...if someone has good outputs but no inputs, that’s not a fit for our system because it’s luck, and we can’t be convicted they’ll reproduce it." (33:58)
• "Venture brand decay—the default trend is decay unless you reinvent. Most successful firms don’t do that." (49:09)
• "Portfolio services are only impactful if they are true value creation, not marketing." (53:24)
• "We’re an Ironman suit—the founder plugs in early; later they build their own machinery." (55:14)
