Jack Dorsey’s #1 rule for pitching your startup: “Show them something that works” Jack Dorsey, Jim McKelvey, and another engineer built the initial prototype for Square in a month. As Jack recalls: “I could actually swipe a card, generate an electronic receipt via email, and then send it out to a person. I loved this because I would go around to all these angel investors and VCs and charge them $5-50 to show them my new idea.” This prototype was critical in helping the company raise $10 million in initial funding from Khosla Ventures. And Jack believes it’s a lesson all founders should take to heart: “The thing that really inspires people is a working product. When you’re pitching someone, the best thing you can do is show them something that works.” Jack continues: “We did this with Twitter. We had a great number of users… and we had investors who were coming to us who were already users of the product. Their families were users of the product. So the story became very easy to tell and they could easily see why this was something that was powerful.” Video source: @Stanford (2011)

Sam Altman: “One of the few arbitrage opportunities left in the market is time” “I don’t think you can beat the market in a lot of ways, but the one way I do is by making a long-term commitment to something. My new belief on how long I should hold stock in the best companies I invest in is forever. And I think in a world where people are increasingly focused on the tick and the quarterly earnings cycle, you should try to go in the other direction. This is a great way to generate value and wealth.” Sam continues: “And so I think that when you’re thinking about a startup, it’s really worthwhile to think about something you’re willing to make a very long-term commitment to because that is where the current void in the market is. You get paid as a founder for the wealth you create for other people… The best companies just create massive amounts of value for the world, and then they capture some of that for themselves. But they capture far less than they create, and they do it over a very long period of time. So if you’re going to be one of those companies, I think you want to make a super long-term commitment to yourself and others that are going to work on it with you… It is worth waiting because you will make far more money over the long term by doing this company really well than a bunch of short term things along the way.” Video source: @ycombinator (2016)

Congrats to @Starcloud_ on their $170M Series A at a $1.1B valuation! They're building data centers in space—just 17 months from YC Demo Day to unicorn. They launched their first satellite with an Nvidia H100 GPU last year and are now developing Starcloud-3, a spacecraft designed to launch from Starship that aims to be cost-competitive with Earth-based data centers for AI inference. techcrunch.com/2026/03/30/sta…

Steve Jobs explains the importance of both thinking and doing “The doers are the major thinkers. The people that really create the things that change this industry are both the thinker-doer in one person.” This is applicable outside of tech too, and he uses Leonardo DaVinci as an example: “Did Leonardo have a guy off to the side that was thinking five years into the future about what he would paint or the technology he would use to paint it? Of course not. Leonardo was the artist, but he also mixed his own paints. He also was a fairly good chemist. Knew about pigments. Knew about human anatomy. And combining all of those skills together—the art and the science, the thinking and the doing—is what resulted in the exceptional result… There is no difference in our industry. The people that have really made the contributions have been the thinkers and the doers.” Jobs speculates that one of the reasons people might mix this up is because it’s easy to take credit for the thinking: “It’s very easy for someone to say ‘I thought of this three years ago.’ But usually when you dig a little deeper you find that the people who really did it were also the people who worked through the hard intellectual problems.”

The energy war just changed. America burns coal at night to keep the lights on while China built something different and most people have no idea it exists. In the middle of the Gobi Desert, there is a 263-meter tower surrounded by 12,000 mirrors in a perfect circle, spread across nearly 8 square kilometers of barren land. It looks like something out of a science fiction film. They are focused on a single point at the top of that tower, raising temperatures above 800 degrees Fahrenheit. That heat gets pumped into tanks filled with a special liquid salt mixture. They are using Molten salt, the same stuff ancient civilizations used to preserve food is now storing the sun's energy at 565 degrees Celsius. When the sun goes down, the plant keeps generating electricity. The molten salt stays hot for hours after sunset and drives a steam turbine on demand. This is a 100-megawatt power station that runs 24 hours a day on sunlight alone. It produces over 390 million kilowatt-hours of power every single year. Every coal plant on earth has one critical weakness, it needs fuel to burn. This plant needs nothing but the sun and a tank full of heated salt that refuses to cool down. The implications are enormous. The oldest argument against solar energy has always been: "What happens at night?" China just answered that question with 12,000 mirrors and a tower visible from space.

Peter Thiel tells the founding story of PayPal “When you start one of these companies, it’s typically not the case that you get the whole idea fully formed instantaneously,” Thiel begins. “There was this incredible internet boom going on in Silicon Valley in the late 1990s. It felt like there was this open frontier or gold rush, and one of the natural things to look at was finance.” At the time, Thiel was very interested in the idea of creating new forms of money. “There’s always something super mysterious, powerful, and important about money,” He explains. “And we had this general idea to do something with security, money, and payments very early on in the founding of the company. Then you iterate a lot on how to get the idea out.” Thiel continues: “The critical question for any consumer internet product is not what the idea is, but ‘how do you get distribution?’ There had been a lot of internet payments companies that had already started and failed by 1998… They would’ve worked if everybody used them, but you could never get the first person to start. So the challenge was how to make it go viral and how to get something to work where it’s good for the first person, the 10th person, and the 100th person. Once you have millions of people, you have a network and network effects. That was sort of the chicken and egg problem we wanted to solve.” Eventually the team stumbled on the idea of linking money with email: “There were already 300 million people in 1999 that had email accounts. So if you could send money to an email address… you didn’t need both counterparts to a transaction to be part of the PayPal network. Only the sender could be part of it, and then the recipient would sign up as they took money out. We started with the 24 people in our office, and they sent money to friends and other people. Then we gave these referral bonuses of $10 if you got someone to sign up, and it just grew exponentially. It grew about 7-10% compounding daily… We had 1,000 people in mid-November of 1999. By the end of December it was 12,000. By February 3, 2000, it was 100,000. By mid-April 2000, it was up to a million.” The other critical component of PayPal’s success was starting with customers who had an intense need and minimal downside risk: “One of the natural places that it started was on the eBay auction site where you had small dollar transactions of maybe $40 as the typical amount. If you send a check across the country, that’s a 10 day delay. It’s slow, and most people aren’t set up to process credit cards.” Thiel reflects on what it felt like to go from 1,000 users to 1 million in just a few months: “[It felt like] you were at the forefront of some sort of revolutionary thing. It’s incredibly exciting and incredibly scary. It was like ‘we’re going to take over the world’ or ‘we’re all going to die’ and you move between those two several times a day.” Fraud was a major challenge the company had to solve — especially because making a product hard to defraud is usually at odds with making it easy to use. Thiel had an interesting perspective of operating in strange regulatory zone with this new form of moving money: “I often thought of it at the time that we were in a race between technology and politics. The politicians didn’t like us, but if we got the PayPal network to be big enough, it would sort of overwhelm the regulators and they’d have to accept it as a fait accompli… One of the execs at PayPal said we needed to hire a whole bunch of lawyers to tell us what we can or can’t do, and we said no we’re not going to hire them. They’ll just tell us what we can’t do. We have to just go ahead and not hire the lawyers and just do it.” Video source: @RubinReport @RubinReportShow (2018)

"Speed wins." "You have to be willing to commit to being fast. You can't have long bureaucratic processes. You can't have a risk-averse posture." @pmarca explains the OODA loop — and why the fastest operator controls the narrative in business, media, and politics: "There's a framework called the OODA loop, originally developed for fighter pilots and later for broader military strategy." "It stands for observe, orient, decide, act. It's basically the decision-making cycle." "If speed is the thing that matters, then the person who gets through that cycle the fastest is the one who's going to win." "If you can have a sustainably faster OODA loop processing cycle than the next guy — think about what happens… You operate and make a decision within an hour. The other guy is still inside his own OODA loop when you make your decision. He's only halfway through his process and now has to start over. You've changed the parameters of what's going on." "This is also a big explanation for what's happened in traditional media." "The New York Times has its own OODA loop, and it's like 24 hours to go through its process."
