Great data, but I'm pretty disappointed with many of the other conclusions. In the opening line the article states that the 5 largest tech companies were founded by those age 30 and lower. Why? The article isn't very helpful here. It seems to say that they are anomalies, which is a little unsatisfying. > "one may reconcile the existence of great young entrepreneurs with the advantages of middle age by noting that extremely talented people are also extremely talented when they are young." So they destroy the myth of the young founder, by perpetuating the myth that these founders were superhuman (extremely talented is the word they used). As evidenced by valuations of their companies continuing to rise as they got older. I find Malcom Gladwell's conclusion more satisfying: When the internet was born, these people were closest to it in - in part because they were young. I'd extend Gladwell to argue: In once in a lifetime technology revolutions, the young may be advantaged in creating a handful of super valuable companies. And those companies are so central and their small head start is so so powerful, that those companies succeed, at times in spite of their founders. My conclusion: If you happen to be in college during a technological revolution, you won the lottery and should start a company. Otherwise, you are better off learning, accumulate resources, and founding late in your career.

      Its a little deeper than that: Never underestimate how willing other people are to spend money on things that you consider frivolous. The trap is to accidentally consider your values as universals. You haven't known obsession until you've hung out with some model railroad guys.

  I'd tweak that heuristic to say that you'll be entered into a lottery regardless, and as such it makes sense to figure out which revolution you're in the midst of. In the 1960's you probably could have flipped a coin between tech and advertising.
  - samsonradu 8y ago
    I would also add that it's not easy to tell which revolution you're in the midst of (if any). VR technology was also thought to be a revolution a decade back and it hasn't really delivered. Or take crypto for instance. Is it a financial revolution that will build a mega-corp like Amazon or Google in the upcoming decades or will it slowly fade away.

I don't see Steve Jobs or Jeff Bezos as counterexamples to the article's thesis. Jobs specifically was a much, much better CEO in middle age than he was in his youth. I think the same is true for Bezos. These folks were outliers when they were young, and they were even more extreme outliers after decades of experience. Also, Gladwell's conclusion is only true for 2 of the 5 companies mentioned.

  Steve Jobs was young when personal computing was young. Likewise, Jeff Bezos and the internet. These people succeeded despite themselves and became better with age. These all fit with the OPs argument.

Yup. Well put. For more, if want to do a startup with the advantage of some original research that is not yet a fad or hot topic, research you are likely the only who will do it, there's no rush, under 30 won't have the prerequisites. The problem to be solved doesn't have to be new, hot, or a fad but in whole or in significant part so far just solved poorly or not at all and where some good research can get the first good or a much better solution. Such research is not the well worn path down Sand Hill Road to $1 T, but so far not even Sand Hill Road has such a well worn path. There are only a few $1 T cases or candidates so far; the patterns are not attractive; and from elsewhere, especially US national security, research has a much more promising track record. Uh, for Silicon Valley, how old was Shockley? How old was Tukey when he did the FFT? How old is Irving?
savanaly 8y ago
Maybe it's that it's more expensive to do a startup as an older person (your time is more valuable since you've built up more skills, for example), so as a result startups that are founded by older people are the ones with unusually strong premises or reasons for being. It could be a selection effect.

    - Retric 8y ago
      The Islamic Golden Age has a nice name, but represented little actual scientific or technological progress relative to a 600 year time period. For comparison the European dark ages had quite a bit of progress in algebra, farming etc, but again covered several hundred years so progress was slow.
      - mnl 8y ago
        Just no, and I don't understand what's the point in posting uneducated personal opinions here and stating them as facts. The "European dark ages" had literally zero progress in algebra, it was Boethius's De arithmetica in the Quadrivium for six centuries until Fibonacci's Liber abaci introduced the hindu-arabic numbers, which he learned in what today we call Algeria. And then algebraic methods (BTW "algorithm" comes from the name of al-Khwarizmi, "algebra" comes from "al-jabr") were unknown in Europe until Robert of Chester translated Khwarizmi's "Hisab Al-jabr w'al-muqabala" to Latin from the original in Arabic. There was zero progress in algebra in Europe for six centuries because they had no algebra. After that (there was a bit of a divide between abacists and algebrists), people doing algebra in Europe used that book until the printed arithmetics/algebras of the 16th century. All of them do mention their sources: you can download them in google books and look it up.

> My conclusion: If you happen to be in college during a technological revolution, you won the lottery and should start a company. Otherwise, you are better off learning, accumulate resources, and founding late in your career. This seems to be major selectivity bias. Let's call the development of the internet a major technological revolution. How many successful startups have emerged over the time since that revolution began? AOL was started in what, the early 90's? Yahoo was started in the mid-90's. Google was started in the late-90's. Facebook was started in 2004. Twitter, 2007? AirBnB, 2009? Stitch Fix, 2015 or so? The idea that there's a small window to create a valuable startup right after a tech revolution has begun seems to make sense at first glance, but after more thorough investigation pretty much falls apart. There's never an easy time to create a company like that. It requires intelligence, connections, luck, execution, persistence, and a million other factors. Put another way, if anyone could go back to 1995 knowing what they know now, I would bet that almost nobody could recreate Google or Facebook because of all the hidden difficulties of launching them that is glossed over now that we are 15+ years out from their launches. Meanwhile, a guy like Bill Gates would probably have enormous success in pretty much any line of business (albeit not at the scale that Microsoft has had), but far greater than the average founder.

    Bill Gates is indeed talented and hard working -- and generous in some ways. He also dumpster-dived to learn how to write good software from looking at other people's code without their explicit permission: https://patch.com/california/losaltos/microsoft-co-founder-paul-allen-recounts-his-days-of-7a8784789a https://patch.com/california/losaltos/microsoft-co-founder-p...

"I would boost Bill into dumpsters and we'd get these coffee-stained texts (of computer code)" from behind the offices, grinned Allen."" And MS-DOS is based in part on CP/M's design: "MS-DOS paternity suit settled: Computer pioneer Kildall vindicated, from beyond the grave" http://www.theregister.co.uk/2007/07/30/msdos_paternity_suit_resolved/ http://www.theregister.co.uk/2007/07/30/msdos_paternity_suit... "Last week, a Judge dismissed a defamation law suit brought by Tim Paterson, who sold a computer operating system to Microsoft in 1980, against journalist and author Sir Harold Evans and his publisher Little Brown. The software became the basis of Microsoft's MS-DOS monopoly, and the basis of its dominance of the PC industry. But history has overlooked the contribution of Kildall, who Evans justifiably described as "the true founder of the personal computer revolution and the father of PC software" in a book published three years ago. In a chapter devoted to Kildall in Evans' They Made America: From the Steam Engine to the Search Engine: Two Centuries of Innovators, Evans related how Paterson "[took] 'a ride on' Kildall's operating system, appropriated the 'look and feel' of [Kildall's] CP/M operating system, and copied much of his operating system interface from CP/M."" If you want to get away with such things, it helps to start rich, of course: http://philip.greenspun.com/bg/ http://philip.greenspun.com/bg/ "William Henry Gates III made his best decision on October 28, 1955, the night he was born. He chose J.W. Maxwell as his great-grandfather. Maxwell founded Seattle's National City Bank in 1906. His son, James Willard Maxwell was also a banker and established a million-dollar trust fund for William (Bill) Henry Gates III. In some of the later lessons, you will be encouraged to take entrepreneurial risks. You may find it comforting to remember that at any time you can fall back on a trust fund worth many millions of 1998 dollars." And to have free legal advice from his father (a lawyer). Contrast all that with the hypocritical letter Bill Gates wrote: https://en.wikipedia.org/wiki/Open_Letter_to_Hobbyists https://en.wikipedia.org/wiki/Open_Letter_to_Hobbyists "As the majority of hobbyists must be aware, most of you steal your software. Hardware must be paid for, but software is something to share. Who cares if the people who worked on it get paid Is this fair? One thing you don't do by stealing software is get back at MITS for some problem you may have had. MITS doesn't make money selling software. The royalty paid to us, the manual, the tape and the overhead make it a break-even operation. One thing you do do is prevent good software from being written. Who can afford to do professional work for nothing? What hobbyist can put 3-man years into programming, finding all bugs, documenting his product and distribute for free?" So wrote the millionaire dumpster diver who could afford to write free software his whole life -- but chose instead to resell an OS that ripped-off someone else's hard work (one reason IBM may have wanted to keep an arms-length distance from MS-DOS instead of buying it outright). Those are hypocritical words to anyone who knows more of the story, but brilliant marketing -- including the rhetorical deception about how much time free software developers might have (such as ones at universities or government labs or students like, then, Linus Torvalds). [Stuff I previously mentioned here: https://news.ycombinator.com/item?id=15772233 https://news.ycombinator.com/item?id=15772233 ] To be clear: just because Bill Gates did stuff like that in his teens and 20s does not mean he would do stuff like that now. He many have grown as a person in many ways over the past few decades (e.g. the Gates Foundation).

Hewlett and Packard fit this pattern. Arguably Robert Noyce also. You can't really do stats on outliers without binning stuff into a histogram. The 5 sigma entrepreneurs were probably young just out of survivor bias. The guy who cofounds Fairchild semiconductor and gives it his name (Sherman Fairchild) doesn't count as the world's greatest semiconductor entrepreneur because he died significantly before his cofounders did.

A lot of it boils down to different priorities at different ages. If I had started Facebook at 19 and Yahoo offered me $1 billion for it, I probably would have made the same decision Zuckerberg did and say that running Facebook is more fun than having $1 billion. If I founded Facebook today, I’d take the first offer that put >$10 million and run off to play with my kids, and you’d never have heard of Facebook again.

I think it's even simpler than this: most people learn their primary skillsets when they are young, and start businesses when they see large opportunities for themselves. Because most people learn their skills when they are young (and most don't pick up new technological skillsets after ~30), the logical consequence is that the young tend to be more tech-savvy. As industries mature, the barriers to entry (and domination) increase. Again, as a logical consequence, the youngest industries (which have the youngest practitioners due to the above) has provides best opportunities for entrepreneurs. As a result, would-be entrepreneurs of Google/Facebook/Amazon stature are going to skew young. And seeing as starting a Google/Facebook/Amazon requires as much (if not more) luck as it does entrepreneurial talent, it only makes sense that the group who holds the most lottery tickets is going to hold the most winning lottery tickets. Notice that the above logic requires zero assumptions about the relative skill of older or younger entrepreneurs. It's mostly just a numbers game. My suspicion is that, "per capita", older entrepreneurs who have kept up with the most recent technological advances are more likely to be successful than their younger counterparts... but I'll be the first to admit I'm just idly speculating.
