Swedish Founders Should Leave for Silicon Valley, Then Return

The central prescription Paul Graham offered Swedish founders was not permanent emigration. It was temporary immersion followed by deliberate return. Founders should go to Silicon Valley because intense fields tend to have a single global center; Stockholm should want some of them to come back because returning founders can bring back better companies, capital, and habits formed in the world’s densest startup environment.

Graham framed the founder’s decision as an old pattern with a startup label. In every field where ambitious people work intensely, he said, one place tends to become the center: Paris for painting in 1870, Göttingen for mathematics in 1900, Hollywood for movies in 1950. The question for founders is the same one ambitious painters, mathematicians, and filmmakers faced: should they go there?

His answer was blunt: yes. Not necessarily forever, and not as an act of abandoning home. “You can go there for a bit and then come back,” he said, “but you should at least go.” The reasoning, in his view, does not change merely because a founder crosses a national border. If a person interested in startups lived in a small village, it would be obvious that moving to the capital would help, because there would be more people working on the same thing. A border is just “a dotted line on a map”; the logic of concentration does not know it is there.

The practical claim was not that Silicon Valley is symbolically important, or that founders should acquire its aesthetic. Startup work benefits from unusually dense concentrations of relevant people. Graham described the “big center” as a place where the talent pool expands in two dimensions: the people are better, and there are more of them. Because they also cluster in particular places, the resulting concentration becomes, in his word, “intoxicating.”

He compared the feel of a Y Combinator batch dinner to the room in Stockholm: many people working seriously on similar problems, seeing one another every week for months. That concentration matters first for morale. Graham referred to Gustav, who had said that when he arrived in Silicon Valley he felt he had finally met his people. But morale was the lesser benefit. The more important benefit was the number of valuable accidental encounters.

Graham spent time on serendipitous meetings because he believes their importance is visible in biographies and still hard to explain. People who do great things often have some unplanned meeting that changes their life. He offered several possible explanations without settling on one.

One possibility is simple volume: there are more unplanned meetings than planned ones, so more of the extreme outcomes come from the unplanned set. Another is that “unplannedness” itself may be useful. Planned meetings require a reason beforehand, and that requirement may make them too conservative. Graham compared this to deliberately trying to find startup ideas, which in his view can “lop off the outliers.” If one must already know why a meeting is worth having, the most surprising possibilities may never be reached.

A third possibility is selection. In an unplanned encounter, people can decide after the first few sentences whether to continue. If those first sentences reveal a strong shared interest — “Oh, you’re interested in that too?” — the conversation can immediately become serious. The value lies not in random socializing, but in random access to unusually relevant people.

The claim was specific. Founders do not benefit from any dense city simply because it is dense. They benefit from a center where the people around them are working on the same class of hard problem, where chance encounters are more likely to be with people whose judgment, connections, or standards can change what happens next.

Things move faster in startup centers because the people there are more confident, more decisive, and more exposed to one another’s ambition. They “egg one another on,” both by encouragement and rivalry. Outside the center, Graham said, people may half-have ideas and never act on them. Years later, when a large startup succeeds, they say they had thought of the same thing.

For founders, fundraising is the most important special case of this speed. Investors in Silicon Valley, Graham said, decide much faster than investors in Europe. Part of that is confidence. Another part is competition: if an investor correctly sees that a startup is worth backing, that very correctness means the opportunity may disappear quickly. “The more right you are,” he said, “the less time you can wait.”

He illustrated this with Yuri Sagalov investing immediately after meeting Max, because Sagalov believed anyone else who met him would want to invest too. Graham described that as characteristic of the valley. Investors complain about it — valuations are high, decisions are rushed, companies raise instantly, and investors have little time to get to know founders — but he said the rush has not empirically hurt them. Silicon Valley investors, he said, get better returns than European investors despite having to decide so quickly.

The speed advantage also changes how outsiders perceive a startup. Graham said founders who leave for Silicon Valley often receive more respect back home. Invoking the line that no one is a prophet in their own country, he said investors outside Silicon Valley tend to implicitly assume local startups are second-rate. He emphasized that this is not uniquely Swedish; in his view, it happens everywhere outside the valley.

Going to Silicon Valley reverses that assumption. Sometimes founders do not even need to move. Once they announce that they have been accepted into Y Combinator, local investors who had previously hesitated may suddenly compete to invest, because they understand that once the startup reaches the “big city,” other investors will see it too.

Graham’s clearest example of local investors changing their minds too late was Dropbox in the summer of 2007. Dropbox came from Boston, and Graham said that a large Boston venture firm had spent the previous year keeping “a benevolent eye” on the company: offering encouragement and advice, but not money.

At the time, Graham said, Y Combinator would fly Boston startups to Silicon Valley for a second Demo Day after the Boston Demo Day because the Boston investors were “so lame” that the startups needed to go west to raise money. When Dropbox reached Silicon Valley, Sequoia became interested. Once the Boston firm found out, its view of Dropbox changed abruptly. Graham said the firm sent Drew, the founder, a term sheet by fax with a blank valuation — effectively saying it would invest at any price.

It was too late. Drew went with Sequoia. Graham noted that in 2018 Dropbox became the first YC company to go public.

For Graham, the Dropbox example showed how the center can alter a company’s perceived value. A startup can look optional when it is local and suddenly become urgent when elite investors elsewhere show interest. The founder’s move, or even the founder’s proximity to the center, changes the investor’s interpretation of the same underlying company.

The largest advantage of moving to a startup center, Graham said, is not what it gives founders, but what it does to them. A “big fish in a small pond” cannot tell how big a fish it is. In a larger pond, founders can measure themselves against people known to be exceptional.

He named Brian Chesky and Sam Altman as examples of people a founder might encounter and think: this person is very impressive, but not a different species. The point is not self-congratulation. A serious founder does not look at such people and think, “I’m as good as that.” The more useful thought is: “I could be like that if I worked as hard.”

That distinction mattered enough that Graham repeated it. The encounter makes the goal no longer impossible, only hard. For an ambitious person, he said, “there is nothing better than a high but definite threshold.” Seeing someone very successful at close range clarifies both that the summit exists and how high it is.

Graham used Max, a Swedish founder present at the event, as the live example. He joked that Max was “pretty much as big a fish as they get” and, because he was Swedish, called him a “Swedish fish.” But the substantive point was that Max illustrated both sides of the standard: a Swedish founder could do it, and the amount of work required would be severe.

There are founders, Graham conceded, who see such people and conclude they could never do what they do. But he said this happens less often than one might expect. One reason is that successful founders who speak at YC are not there to intimidate the batch. They are there to encourage them, and they try to seem accessible. Max, he joked, was still “just raw terrifying,” but the intended function was the same: to make extreme achievement legible rather than mythical.

Graham described another effect of moving to Silicon Valley as subtler: it makes people more helpful. He put the valley’s norm starkly: “In Silicon Valley, people help you for no reason.” To people in the valley, that sentence would sound odd, just as telling Swedes that Swedish streets are clean “for no reason” would sound odd. The local reaction would be: why would you need a reason?

He distinguished this from ordinary politeness. Graham said he had invested in a couple of companies founded by people in England and asked one that had moved to Silicon Valley how the experience differed from expectations. The founders said the most surprising thing was how helpful everyone was; conversations seemed to end with “What can I do to help you?” When Graham asked whether England was like that, they laughed and said no. Since English people are, in his telling, more polite than Americans, the difference could not simply be manners.

His explanation was evolutionary. Silicon Valley is a place where people go from being nobodies to billionaires faster than anywhere else, he said. Someone with a habit of being kind to nobodies is therefore unusually likely to end up with powerful friends, and possibly rich ones. Even if such behavior began as calculated, Graham argued, it no longer feels calculated. After 60 years, it has become custom.

Ron Conway was Graham’s emblem of this norm. Graham said Conway spends all day helping people and does not even track whether they are his own portfolio companies. He does not remember many of the favors he does. That lets Conway operate at a larger scale: like an honest person who does not need to remember lies, he does not need to maintain a ledger of favors.

This was the bridge from the individual founder’s decision to Stockholm’s institutional question. If founders go to Silicon Valley and absorb that culture, then return, the claim is that they do not only bring back contacts or money. They bring back a changed default about helping other founders.

The answer to what Stockholm should do to thrive as a startup hub was embedded in the answer to founders: go to Silicon Valley for a while, then come back. Graham anticipated that this might sound controversial — helping Sweden by going to America — but returned to his historical analogy. It would not have helped 19th-century Swedish mathematics, he argued, for mathematicians to boycott Göttingen in the name of developing Swedish mathematics at home. In fact, he said, the Swedish government at the time gave fellowships conditional on mathematicians leaving to study in other countries.

Founders who go to Silicon Valley and return help Sweden in three ways, according to Graham. First, they improve their own startups, raising the average quality of companies in Stockholm. Second, they are likely to bring back money from Silicon Valley investors. Third, they import Silicon Valley startup culture, which he described as having evolved over decades to be optimal for startups.

He also argued that this imported culture is unusually compatible with Swedish culture. It lacks the “tall poppies” attitude, which he said Sweden should probably lose anyway, but it shares a high-trust element. His prescription was not for Sweden to stay isolated in order to build a local startup hub. It was for founders to acquire what he sees as the center’s advantages — stronger companies, capital, and startup culture — and return with them.

The trade-off is real in his own account. Silicon Valley may maximize the individual startup’s odds by concentrating peers, capital, ambition, speed, and help. Stockholm benefits only if enough founders treat that concentration as a place to learn from rather than a place to disappear into permanently. Graham’s argument for leaving was therefore also an argument for making return socially and practically valuable.

Graham acknowledged that recommending Y Combinator as the optimal way to experience Silicon Valley could sound self-interested. He nevertheless argued that YC is deliberately designed to concentrate what is distinctive about the valley. He called it “a little super-valley within the valley.”

The claimed advantages were density, mutual help, and investor urgency. In YC, everyone around a founder is also a startup founder, which creates instant colleagues. They are more committed than usual to helping one another because that is one of YC’s principles. Even the compressed decision-making of investors becomes more extreme, “down to the minute.” And founders can experience all of this in roughly four to six months.

From Sweden’s perspective, Graham argued, YC would look like an implausibly effective government program if the government had designed it: a way for Swedish founders to experience Silicon Valley, funded by Silicon Valley investors, at no cost to Sweden. “They don’t even have to license it,” he said. “They can just call our API.”

The caveat was important. For this to help Stockholm, the startups have to come back. Graham said YC has a lot of data showing that startups that go home after YC do not do as well as those that stay. Specifically, companies that return home are about half as likely to become unicorns.

He gave three reasons not to overread that figure. First, selection bias: the data may reflect founder confidence and determination as much as the causal effect of location. Founders more willing to move countries for a startup may already differ from those who return. Second, the measure is valuation, not necessarily company performance, and Bay Area companies can raise money at higher valuations. Third, even if returning halves the outcome, the result can still be large enough. If a founder would have become a billionaire in the valley and instead ends up with $500 million, Graham said, the practical difference is not meaningful; converted into kronor, it sounds even larger.

Then he added a non-financial reason to return. Money is not everything, he said, noting the irony of an investor saying so. Once founders have children, they may care more about where those children grow up than about maximizing the company. Eventually, in his view, that becomes the most important question.

If Stockholm succeeds at transplanting enough of Silicon Valley’s startup culture, Graham said, it could become “the Silicon Valley of Europe.” He argued that the role is still available. If people are asked where the Silicon Valley of Europe is, there is no obvious answer. If there were, the question would sound absurd, just as nobody asks where the Silicon Valley of America is.

He anticipated the objection that Stockholm is pleasant but not especially large or centrally located. His reply was Mountain View, California. He described it as a backwater even now, and asked the audience to imagine it in 1955, when Shockley Semiconductor was being founded. Yet Mountain View was the center of Silicon Valley, at least geometrically, until 2012, when Graham said the center shifted to San Francisco.

For Graham, the requirements are simpler than size or centrality: a place founders want to live, and a critical mass of founders. He said Stockholm, from what he could tell by being there, is the kind of place founders want to live. The unknown is the critical mass. But critical masses are hard to detect before they happen. “You don’t know till you hit it,” he said, “and then, pow.”

The opportunity, as Graham described it, depends on founders leaving and returning with the three benefits he named: better startups, Silicon Valley investor money, and imported startup culture. His argument for Stockholm was not that every ambitious founder should stay home. It was that enough founders should come back for those gains to accumulate locally. The tension is that Silicon Valley is presented as the individually advantageous place to stay, while Stockholm’s upside depends on founders choosing not to optimize only for that advantage.
