The Team You Build
= The Company
You Build

"Wrong people, everything is difficult. Right people, everything else will be easy."
, Vinod Khosla to Rabois at Square

Hiring is a muscle, exercise it constantly
PayPal's density powered 25 yrs of great companies
Build on undiscovered talent, not known names

Framework

Barrels & Ammunition

BARREL

inception → success

AMMO

supports & executes

2–15

barrels at
any company

254

PayPal people
17 barrels

barrels at
a big co

"Hiring more people without more barrels stacks them behind the same initiatives, coordination tax kills speed."

Barrel = fire and forget. Comes back with problems + solutions.
Barrels : ammo ratio defines your parallel capacity

Hiring

Finding Undiscovered Talent

TALENT MARKET ALPHA

★ alpha

everyone wants them no data points yet

20 references per senior hire (DoorDash)
Don't stop until you hit a negative ref
"If you were CEO of X, what'd you change?" → "Why couldn't you convince them?"
30-day check: "Would you rehire?" = as accurate as 2-yr review
Less data = more alpha. Skew younger.

The Smoothie Test Intern, day 2: "I'll solve it." Cold smoothies at 9pm. That's a barrel.

Leadership

The CEO's Only Job: Relentless Application of Force

"The better you're doing, the more the CEO should push. The single role: offsetting complacency."

"Top talent morale goes ↓ when coasting. They want to drive and create, not skate."

📈 WHEN THRIVING

Be critical, isolate future problems now
Polish, master details, raise the bar
The more success → the more you push

📉 WHEN STRUGGLING

Be supportive, they already know
Sell the future, coach not criticize
Save criticism for when they're winning

🏆 THE RESET RULE

"Winning a Super Bowl, record goes back to zero. Start fresh every quarter. No skating on last year."

AI Era

The AI Era
Survival Guide

Traditional PM role → fading fast
#1 AI token consumer = the CMO
Business acumen is the new premium skill
Intellectual curiosity > working harder
No year-long roadmaps. Ship next week.

Shopify Model No PowerPoints on product for 2+ years. Every presentation = a working demo.

Contrarian

Hard Truths Nobody Tells You

✗ Talk to customers INSTEAD → ✓ Real world = clutter + distractions. Isolated focus groups are directionally wrong.

✗ Psychological safety INSTEAD → ✓ "High-performance machines are about winning." Criticize in public. Praise in private.

✗ Compete for known talent INSTEAD → ✓ You have 1/10th the salary cap. Undiscovered people = your only unfair advantage.

✗ Year-long roadmaps INSTEAD → ✓ Impossible in November, easy in March. Notice this week → ship it next week.
