The tech industry isn't shaped by ideas. It's shaped by the personality types of the people who have the power to execute them.
Nineteen tech leaders. Seven Enneagram types. Every major decision—which AI gets built, which platform gets funded, which industry gets disrupted—is filtered through the psychological wiring of a small group of people whose personality patterns are surprisingly predictable.
This series maps those patterns. Not as gossip. As intelligence.

The Series
1. The AI Wars: Who Gets to Build God?
Cast: Sam Altman (Type 4) vs Dario Amodei (Type 5) vs Elon Musk (Type 5)
The most consequential technology in human history is being built by three men who fundamentally cannot agree—not because they see different data, but because they ARE different people. A Type 4 who needs to be the one who does it. A Type 5 who needs to contain it. Another Type 5 who needs to own it. The Altman-Amodei split at OpenAI may be the most important personality collision in tech history.
2. The Platform Emperors: How Personality Types Shape the Products Billions Use
Cast: Mark Zuckerberg (Type 5) vs Jeff Bezos (Type 8) vs Jack Dorsey (Type 5) vs Elon Musk (Type 5)
Facebook feels like surveillance. Amazon feels frictionless. Twitter felt unmanaged. X feels chaotic. That’s not design philosophy—it’s personality type. When a 5 builds a platform, it watches. When an 8 builds a platform, it dominates. And when a different 5 takes over a platform built by the first 5, you get the most expensive personality study in history.
3. Founders vs Stewards: The Personality Types That Replace Visionaries
Cast: Steve Jobs (Type 1) → Tim Cook (Type 1), Bill Gates (Type 5) → Satya Nadella (Type 5), Founders → Sundar Pichai (Type 9)
Apple replaced a 1 with a 1. Microsoft replaced a 5 with a 5. Google replaced its founders with a 9. The successor’s personality type reveals what the company actually needed—stability, empathy, or diplomacy—and what it was willing to sacrifice: magic, killer instinct, or ambition.
4. The PayPal Mafia: How One Company Produced More Tech Billionaires Than Any Startup in History (Coming soon)
Cast: Peter Thiel (Type 6) + Elon Musk (Type 5) + David Sacks (Type 6)
Two 6s and a 5 walked into a startup. Then they split up and conquered separate empires. The PayPal Mafia isn’t a network—it’s a loyalty structure forged by specific personality types under specific pressure. Thiel’s contrarian threat-detection. Musk’s systems obsession. Sacks’ operational loyalty. The personality dynamics that made PayPal a billionaire factory.
5. The Disruptors: Why Type 8s Break Industries and Type 5s Decode Them (Coming soon)
Cast: Jeff Bezos (Type 8) vs Reed Hastings (Type 8) vs Travis Kalanick (Type 8) vs Elon Musk (Type 5)
Three 8s and a 5 who destroyed entire industries. The 8s did it through force. The 5 did it through first principles. One of them got ousted. The personality type doesn’t just explain WHO disrupts—it explains who survives the disruption they create.
6. Tech Leadership by Personality Type: How Each Enneagram Type Runs a Company (Coming soon)
Cast: All tech titans, grouped by Enneagram type
The definitive comparison. How Type 1s lead (uncompromising standards), how Type 5s lead (systems and detachment), how Type 8s lead (confrontation and force), and why the types missing from tech leadership (2s, 7s) explain why the industry keeps building powerful products that fail at being humane.
The Pattern Nobody’s Talking About
Here’s what emerges when you map all 17 leaders:
Type 5s run everything. Six of the seventeen leaders are 5s. The most withdrawn, cerebral type on the Enneagram dominates an industry that shapes how billions of humans connect, shop, and communicate. The people building the future are the people most detached from the present.
Type 8s disrupt everything. The three biggest industry disruptions (retail, entertainment, transportation) were all led by 8s. When you need to break something, you need a type that doesn’t flinch.
Type 6s fund everything. The two most influential tech investors/advisors (Thiel, Sacks) are both 6s. The types most attuned to threat and loyalty are the ones deciding which futures get funded.
Types 2, 7, and most of 9 are absent. The helpers, the enthusiasts, and the peacemakers are almost entirely missing from tech leadership. The industry selects for analytical and dominant types—and the products reflect it.
This isn’t a coincidence. It’s a personality monoculture. And it explains why tech keeps building products that are brilliant at systems and terrible at humans.
Understanding these types isn’t gossip. It’s the operating manual for how the future gets decided.
Rabbit Holes Worth Exploring
- The All-In Podcast as Enneagram Lab: Sacks (6), Chamath (3), Calacanis (3), Friedberg (5). Four types debating the future of tech in real-time. Their recurring disagreements map perfectly to their personality types.
- Tech Wives and Partners: Priscilla Chan (Zuckerberg), Lauren Sanchez (Bezos), Grimes (Musk). Do tech titans’ relationship patterns reveal their type dynamics?
- The Loneliness of the Tech Titan: Altman, Musk, and Zuckerberg all describe feeling misunderstood. Is that a function of power, personality type, or both?
- AI Alignment as a Personality Problem: Safety strategies differ because the PEOPLE proposing them differ. A 4’s safety is “the right person leads.” A 5’s safety is “deep understanding first.” An 8’s safety is “I need leverage.”
- The Missing Types: Where are the 2s, 7s, and most 9s in tech leadership? Their absence shapes what gets built and—more importantly—what doesn’t.
