Overview

In this episode, Harry Stebbings has an incisive conversation with David George, General Partner at Andreessen Horowitz, one of the most influential growth investors in the world. They dive deep into the realities and myths of managing multi-billion dollar venture funds, how AI is changing company metrics, the nuances of growth-stage investing, and the logic behind some of the most debated decisions at a16z.

Key Discussion Points & Insights

1. Can Large Venture Funds Really 5×? (04:46–08:11)

• Myth Busting on Large Funds: David George confidently counters the industry notion that large funds cannot achieve high multiples:
  • "Our best performing fund in the history of the firm is actually a $1 billion fund. Databricks returned 7× and Coinbase 5× already." (05:12)
  • The expansion of private markets and tech waves allow for outsized private returns.
• Value Creation Shifting: Almost half of the dollars of gain now happen at late stages (Series C+), with $5T in private tech market cap.
• Implication for LPs: Large funds, when capturing winners, can absolutely deliver 5× returns.

Notable Quote:

“The idea that large funds can't have great returns is just not true in our experience.”
— David George (05:28)

2. Private vs Public Markets & Liquidity Dynamics (08:11–15:20)

• Staying Private Pros and Cons:
  • Benefits to extended private status include increased ownership and less stock volatility.
  • Eventually, liquidity comes; most CEOs don't regret going public (10:56).
• Strategic Choices: a16z usually opts to hold and double down rather than sell in late private rounds.
• Market Structural Shifts:
  • Fewer public companies and deteriorating quality in the public small-cap space.
  • Most new value creation happens in privates, urging institutional LPs to rethink allocation.

Notable Quote:

“Never one of them has said, I regret going public.”
— David George (10:56)

3. Asset Allocation Advice for Institutions (15:20–17:27)

• The smartest institutional capital should lean into venture and privates, especially for tech and AI-led shifts.
• US tech continues to dominate, but Europe is highly investable (17:27), and a16z is backing founders globally.

4. AI, Venture Risk, and Betting at High Prices (19:11–22:42)

• Sometimes venture risk at high valuation is justified for “generational founders” (e.g., Character AI).
• Highest conviction founders command premium pricing due to high likelihood of at least a good outcome.
• Fixing "errors of omission" is built into the growth fund's DNA—coming in later if early-stage partners missed a star.

Notable Quote:

“For extremely special people like that, we're comfortable to step into those situations.”
— David George (19:24)

5. Learning from Investment Mistakes (22:50–24:44)

• a16z constantly analyzes its misses, with the key takeaway: Invest based on “strength of strengths,” not fear of weaknesses.
• Overweighting fear of future (theoretical) competition causes missed opportunities.
• Underestimating TAM is a repeated error.

Notable Quote:

“If you overweight the fear of future theoretical competition, you can always talk yourself out of making an investment.”
— David George (23:37)

6. AI’s Impact on Margins, Revenue, and Business Models (26:43–32:52)

• Transition of Labor to Tech Budgets: True AI success will be measured by technology replacing human labor, as proven by C.H. Robinson’s 40% productivity jump (27:39).
• Revenue Quality in AI: Rapid revenue growth only meaningful if high retention and engagement.
• AI App Margins: Short-term margin skepticism is expected; a16z expects margins to “rationalize” over time. If an “AI company” presents SaaS-level margins without real usage, it’s a red flag.

Notable Quote:

“The history of technology inputs would suggest the margins will rationalize and the margins are going to go up.”
— David George (41:15)

7. “Kingmaking” and Capital as an Advantage (33:38–37:06)

• Preferential attachment (leading resources to the leader) helps, but money alone rarely turns a loser into a winner.
• Scale and brand endorsement from a16z helps founders attract talent and resources.
• Warns against the Vision Fund’s model of “capital as a weapon” without underlying product advantage.

Notable Quote:

“If the investment thesis is our investment is going to make them a winner, it’s probably a pretty flimsy investment thesis.”
— David George (33:57)

8. Controversial Bets and Contrarian Positions (42:29–53:05)

• a16z backs exceptional founders even when the market is confused or skeptical (e.g., Flow with Adam Neumann).
• Adam’s vision: Branding the rental experience, leveraging his world-class talent in brand, organization, and product.
• “Once-in-a-decade” founder profiles drive bold bets.

Notable Quote:

“Adam has extraordinary strengths… he absolutely spikes in the areas that are most important for the business he’s trying to build.”
— David George (51:43)

9. Other Highlighted Segments & Quick Hits

Institutional Knowledge

• a16z’s internal “fix the mistake fund”—purposefully repairing misses from earlier rounds (20:44).

Notable Quotes & Moments

• On Growth and AI Market Dynamics:
  “In the public markets today, you are guilty until proven innocent... you are assumed that you are doomed by AI unless proven otherwise.” (29:20)

• On Margins in AI Startups:
  “On the gross margin point today, I'll say this, we give a little bit more of a pass than we used to. And if we ever see a company that pitches as an AI company and they have SaaS gross margins, we ask a lot of questions.” (42:19)

• On Legendary Founders:
  “How often do you meet a founder like Adam? […] It's probably quite rare, in which case you're like, well, then write the fucking check.” (53:05)
