Outline
Jump quickly between sections.
Each era has a central place for its defining field, and today it's Silicon Valley for tech startups.
High talent density, frequent serendipitous meetings, fast execution, rapid funding, cultural validation, and self-awareness calibration.
Silicon Valley VCs must decide quickly due to competition, unlike slower European counterparts.
Domestic investors often ignore founders until they gain recognition in Silicon Valley, then rush to invest.
YC offers a condensed ‘super Silicon Valley’ experience, immersing founders in 4–6 months.
Founders who return home post-YC face half the unicorn odds, though selection bias and valuation gaps mitigate the gap.

Highlights
Key sentences worth saving and sharing.
Life-changing encounters in biographies are almost always serendipitous meetings — Silicon Valley has an extremely high density of such moments.
European VCs move slowly, while Silicon Valley VCs must decide on the spot — e.g., Yuri Sagalov invested in Max right after meeting.
YC is the 'Silicon Valley within Silicon Valley,' offering a 4–6 month immersion that’s effectively a zero-cost government support program.
In a small pond you feel like a big fish; in the big pond, meeting people like Brian Chesky or Sam Altman shows they’re not another species — you can do it too.
Startups that return home after YC have only half the chance of becoming unicorns compared to those that stay.
When you return, you bring back three things: a better startup, Silicon Valley money, and Silicon Valley culture.
- Larger and stronger peer pool: more talented people, greater numbers, highly concentrated—this density is addictive (every YC dinner feels like this).
- Chemistry from serendipitous encounters: life-changing meetings in biographies are almost always accidental, and such chance encounters are extremely dense in Silicon Valley.
- Faster pace: people are more confident and decisive, mutually inspiring and competing—ideas don’t rot in drawers.
- Investors decide quickly: European VCs move slowly, but due to fierce competition, Silicon Valley VCs must make decisions on the spot (e.g., Yuri Sagalov invested in Max immediately upon meeting). Despite complaints about high valuations and rushed timelines, their returns still outperform European investors.
- Shift in local investor attitude: entrepreneurs aren't respected in their home countries—"a prophet is not honored in his own land." Once you go to Silicon Valley or even just get accepted into YC, local investors suddenly chase after you (the Dropbox story: Boston VCs rushed to send a term sheet with blank valuation upon hearing Sequoia was interested—but were too late).
- Calibrate self-perception: being a big fish in a small pond hides your true size; in a larger pond, meeting people like Brian Chesky, Sam Altman, Max, you realize "they’re not another species—I can achieve this too"—and see how hard they actually work.
- Pay-it-forward culture: people in Silicon Valley help you unconditionally—it's a habit built over 60 years (Ron Conway is the ultimate example). Stay long enough and you’ll naturally become more helpful yourself.
What about Stockholm? Answer: Go to Silicon Valley for a while, then return. The answer to both questions is the same. When you return, you bring back three things:
- A better startup—raising the local average;
- Silicon Valley money;
- Silicon Valley culture—largely compatible with Swedish culture (high trust), except you must drop the "tall poppy syndrome" mindset.
Paul recommends YC as the optimal path: It’s the "super Silicon Valley within Silicon Valley," offering a condensed 4–6 month experience—essentially a zero-cost support program for the Swedish government.
Bad news: YC data shows startups that return home after graduation have only half the probability of becoming unicorns compared to those who stay. But three mitigating factors:
- Selection bias (those bold enough to relocate are inherently more driven)
- Valuation gap (doesn’t equal performance gap)
- Even if it’s only half, it’s still good enough ("in Sweden you’re still a billionaire in kronor").
And once you have kids, you’ll care more about where your children grow up—money isn’t everything.
