Overview

In this engaging and candid episode of The a16z Show, a16z co-founders Marc Andreessen and Ben Horowitz join Paki McCormick to dissect how technology, AI, media, and organizational dynamics are converging to make the next era of innovation 10x – or even 100x – bigger.

The conversation is peppered with sharp insights, personal stories, and plenty of humor, as Marc and Ben reveal what excites them most about the future—and why they’re betting big on the next generation of founders.

Key Discussion Points & Insights

1. The Shifting Information Environment

• Turning Point in Media

  • Marc and Ben recall the 2015 New Yorker profile as the end of an era when mainstream journalism championed free speech (02:32).
  • Marc describes witnessing journalists shift from defenders of expression to advocates for censorship, even recounting direct confrontations regarding Facebook’s moderation stance (03:20).
  • “I was like, that was like my moment. Like journalists are turning against freedom of speech...I felt like gravity like inverted itself and only started to return to normal last year.” — Marc Andreessen (04:20)

• The New Era: Anarchic or Liberated?

  • Marc frames the present as an “uncontrolled, anarchic and liberated” media environment, contrasting it with increasingly draconian regulation attempts in Europe and Australia (05:00).
  • He posits that the era between 2017–2025 was the last gasp of “thought control,” and believes the US has largely restored media openness (05:13).

2. Substack, Non-Fungible Writers, and the Rise of Individual Voices

• Why Bet on Substack?

  • Marc emphasizes that a16z’s Substack investment was about returns and belief in a supply-driven market where enabling writers financially unlocks massive new content (08:30).
  • “If Substack is making its writers successful, then it’s making itself successful...This could be what we call a supply-driven market, which is if you provide the monetization capability, then you’re going to bring into existence writers and content that don’t exist today.” — Marc Andreessen (10:00)
  • Ben highlights Substack’s role in enabling “non-fungible writers”—individual voices who accrue value independently of institutions (11:08).
  • Hamish from Substack argued to Marc that many writers trapped at legacy publications would jump at independent paths if they could support themselves (11:47).

• Content Markets — 10x or 100x?

  • They compare Substack's potential scale to historic shifts in media, suggesting it may become "a thousand times the size" of legacy content industries (14:53).
  • Marc draws parallels with past moral panics about TV and the internet, arguing that supply creates its own demand and there’s huge untapped appetite for quality (16:08).

3. Exponential Growth & the 10x Thesis

• Tech’s Exponential Leaps
  • Ben explains his bold predictions, like Databricks growing 10x bigger than Oracle, as rooted in platform shifts (on-prem → cloud; non-AI → AI) (13:12).
  • “It was just clearly going to be 10 times bigger...those are kinds of things. And look, you have to know your entrepreneur.” — Ben Horowitz (13:12)
  • Marc and Ben agree that technology on the supply side can unlock markets far larger than incumbents ever predicted—Uber riding taxis, cloud riding on-prem, GPUs growing beyond gaming (22:39, 22:44).

4. AI as the “Reinvention of Everything”

• AI’s Transformational Promise
  • "There’s not a problem that we can think of that you won’t be able to solve with AI." — Ben Horowitz (18:26)
  • Ben and Marc illustrate how AI amps up entrepreneurial dynamism—lowering barriers, escalating the scale of ambition, and empowering rapid execution (19:44, 20:08).
  • Marc notes AI has already changed the startup calculus: “In the old days, the product had to be organic, but now you can almost instantly validate ideas and build at an unprecedented pace—AI makes that possible.” (20:08)

5. The a16z Operating System: Confidence, Culture & Reputation

• Empowering Founders

  • Ben describes a16z as “dream builders, not dream killers,” aiming to put inventors into a "virtuous confidence cycle" by giving them access, advice, and credibility (23:29, 25:00).
  • “The purpose of building the dominant venture brand was...to have the companies be able to borrow that at the most critical points in their development.” — Marc Andreessen (29:03)

• Never Taking the Negative: Codifying Culture

  • Prospective a16z partners must literally sign a culture document and attend a session with Ben, committing to never criticize or attack founders or technologies publicly (30:13–31:42).
  • “We do not care if in the moment we think you're making a mistake…We are dream builders. We're not dream killers.” — Ben Horowitz (30:15)

• Reputation as Core Compounding Advantage

  • “We compete on reputation...every relationship matters, everybody who we touch, we try and touch as many people as we can and we try and represent in the very best way possible to build reputation over time.” — Ben Horowitz (33:30)
  • Marc highlights that this reputation transfers powerfully to portfolio companies, helping them close hires, customers, and investors with greater ease (34:40).
  • The power of reputation: raising $15B with only "two AMAs"—far removed from the grind of fundraising 16 years prior (35:33).

6. Organizational Design at Scale

• Ben and Marc insist that a16z avoids “big company” ossification by structuring itself as a series of small, autonomous groups; akin to classic “companies within a company” models (41:36–42:39).
• Decentralized trust: people leading major groups are long-tenured internal talent, not outsiders (43:26).

7. The Art—and Intangibles—of Venture Capital

• The Enduring Human Element

  • Marc muses that venture capital, as “talent/project picking,” is becoming more art than science, especially as technological change accelerates (47:15).
  • “History is a bad guide...the interesting thing about VC for me, probably the biggest lesson, is you gotta be very careful about a highly trained neural net because that's when you make mistakes.” — Ben Horowitz (48:40)

• What Makes a Great Founder?

  • “They all think for themselves. They're not people who read the room and try and figure out what people want them to do.... They're original thinkers.” — Ben Horowitz (51:00)
  • Charisma and followership matter, but every founder is different—no simple formula (51:00).

8. What Excites Them Most About the Future

• Ben: Optimistic that AI is “on the order of the steam engine or electricity,” ushering in a world with dramatically better quality of life. Cautions it should remain grounded in purpose and meaning (52:40).
• Marc: Excited about "Zoomer" founders—tech-native, hyper-competent, unburdened by previous generational angst. “If I had total control over my time, it would be 100% spent with Zoomers.” (54:04, 56:27)
