Ben Horowitz
Ben Horowitz co-founded a16z, manages $46 billion in assets, and helped reopen the Tupac murder case. But the thing he’s most known for — and that actually matters to founders — is that he wrote honestly about failure when everyone else was writing about success.
Why Most Management Books Are Useless
Horowitz’s critique of management writing is blunt: it describes conditions that don’t exist.
“Management books are written like it’s some step-by-step thing that anybody with a basic eighth-grade education can understand. The principles aren’t that complicated.”
What’s missing is the emotional reality. You’re running out of money. You hired people with promises you can no longer keep. You have to fire half the company because of mistakes you made. The level of inconsistency you’re about to embody — the gap between who you told people you were and what you’re about to do — is enormous. How do you say those words? What do you actually say?
Andy Grove’s High Output Management came close. Horowitz wrote The Hard Thing About Hard Things as a sequel, thirty years later. He didn’t want to write it — the publisher asked — so he felt justified calling it what he wanted.
His framework: most CEO failures aren’t failures of competence. They’re failures of confidence. “You could be really smart, but if you wait too long before you pull the trigger, you’re not smart anymore. It’s too late.”
Lead Bullets, Not Silver Bullets
The phrase “no silver bullets, only lead bullets” comes from Horowitz. Shaan picked it up at Twitch from CEO Emmett Shear, and it became one of the two mottos at the top of every MFM growth update.
The story behind it: Horowitz was running his company at a desperate moment, facing brutal competition, the company’s survival at stake. His first instinct was to find the magic solution, the pivot, the rabbit out of the hat.
“I so wanted to stand in front of my company and say ‘aha, I have the answer, here’s what we just have to do and it’ll all work out.’”
Instead he stood up and said: there are no silver bullets. Only lead bullets. We simply have to build a better product. No back door, no escape hatch, no window — we have to go through the front door.
What he found: the silver bullets do exist. But you only discover them by firing so many lead bullets that you stumble onto what actually works. The only way to find the silver bullet is to sincerely believe there isn’t one.
How to Have a Confrontational Conversation
The hardest thing for most CEOs isn’t strategy — it’s the words. What do you actually say to the person who needs to hear something they don’t want to hear?
Horowitz’s approach: stop thinking about yourself. You’re not there to be a tough guy or to be liked. You’re there to isolate the specific thing that needs to change and communicate it in a way the person can actually act on.
His example: a CTO who made a junior employee cry. The CEO didn’t know how to have the conversation without the CTO quitting. Horowitz’s suggested script: “You’re a fantastic director of engineering, but you’re not an effective CTO. If you want to be director of engineering forever, we can run it like that — you do a great job. But a CTO has to marshal resources across the whole company. If you go to a junior person five levels below you and make her cry — you’re probably right, but you’re never going to get what you want out of her.”
The key: people will accept hard feedback if they feel you’re telling the truth. Not soft-pedaling it, not exaggerating it. Just what it actually is.
Culture as Behavior, Not Belief
Horowitz’s theory of culture is that it has to be behavioral or it doesn’t exist. Values on the wall don’t create culture. Daily habits do.
At a16z, if you’re late to a meeting with a founder, it costs you $10 a minute. “What if I had to go to the bathroom?” You owe $50. “What if I had an important call?” $100.
“Why am I paying to work here?” Because building a company is extremely hard, and culturally a16z wants to have ultimate respect for that. The fine forces every partner to plan their day around founder meetings — which embeds the value in behavior rather than aspiration.
The second rule: if you talk smack about an entrepreneur on Twitter — in the portfolio or not — you’re fired. Not suspended. Fired.
“Everyone has integrity until it’s tested. And when it’s tested — when it costs you money, when it costs you a deal — very few people actually have it. You can’t have it in the abstract.”
The samurai called these virtues, not values. A culture is a set of actions.
The Zuckerberg Story
Horowitz’s first conversation with Zuckerberg was in 2007, when Facebook traffic had flatlined and Zuck’s executive team was staging a coup to force a sale to Yahoo.
Zuck’s first question: “If I fired my executive team for the second time, would the board be nervous?”
Horowitz’s answer: “That’s not even the question, Mark, because if you’re asking it, you kind of have to do it — because you can’t succeed with them.”
Then he asked about the traffic problem. Zuck explained it in detail: they’d doubled the engineering team from 400 to 800, new engineers had written straight to MySQL instead of through the API layer, login now took ten seconds, traffic flattened.
“How do you train these guys?” Horowitz asked.
“Train these guys?” Zuck said.
That moment, Horowitz said, was when he understood what kind of CEO Zuckerberg would become. Zuck created a two-month boot camp for every engineer and product manager who entered Facebook. “He is a phenomenal student of management.”
The stereotype of the autistic, low-EQ tech founder is mostly wrong. The ones who truly can’t read people don’t become Mark Zuckerberg. “The guys who are processing information at that rate of speed — you always feel like, what the hell is wrong with my clock, this guy’s thinking faster than me.”
Hip-Hop and the Paid in Full Foundation
Before all of this, Ben Horowitz was in a rap group called the Blind and Deaf Crew — D-E-F — formed after his friend Seth got shot. He grew up between Berkeley and New York, got into hip-hop via DJ Red Alert and Chuck Chillout mixtapes recorded off the radio.
He helped reopen the Tupac murder case, which had been cold for decades. His wife knew QD3, Quincy Jones’s son, who was bitter that Las Vegas had never solved his sister Kada’s boyfriend’s murder. Horowitz arranged a dinner with the Las Vegas Police Department. At the end: “You ought to reopen the Tupac case.” The chief checked with the sheriff. The case was reopened. They caught the man who ordered the shooting.
He runs the Paid in Full Foundation, which provides pensions to the original hip-hop pioneers. Quincy Jones, before he died, told him: “Hip-hop started at exactly the same time they canceled all the music programs in schools.” The drum machine and the sampler freed musicians from needing to be virtuosos. Horowitz sees AI music doing the same thing — again — at a larger scale.
His investment thesis at a16z has moved toward defense tech and AI. But the frame is always the same: founders need someone who will tell them the truth when it matters most, and who has actually survived what they’re going through.
