Tremendous

An angel investor's take on life and business

  • “A whole new world is opening up to you.” That’s what my great grandma said when I learned how to read. 

    I read 34 books in 2025, the most since college. Here are my favorites…

    Book of the Year: On Writing by Stephen King

    On Writing is King’s account of how he became a writer and his advice to other writers. Every day, I use what I learned.

    One of my favorite tricks is to cut 10% of your first draft to reach a tight second draft.

    Writing is thinking. If we get better at writing, we’re better thinkers too.

    Runner Up: The Remains of the Day by Kazuo Ishiguro

    The Remains of the Day is a story about a butler. But it’s so much more than that.

    Ishiguro creates a wonderful little world that I keep coming back to. This was the third time I’ve read this book. 

    Through the character of Stevens, Ishiguro explores the passage of time and the feeling of loss. 

    If you want to learn about storytelling, what could be better than reading the work of a Nobel Prize winner in literature? 

    Honorable Mention: Michael Jordan: The Life by Roland Lazenby

    This is the definitive biography of Michael Jordan. I’ve read several other books on MJ, but none digs as deep.

    I loved playing basketball as a kid, but I wasn’t that good. Still, I looked up to Michael Jordan.

    If you want to excel in anything, Jordan will give you the blueprint.

    The Rest of the List…

    For the remainder of the list, I grouped books by theme. 

    If you have a strong interest in investing, biotech or fiction, feel free to jump to those sections!

    Business and Investing 

    Hetty — Hetty Green was one of the most important investors at the turn of the last century. Called the “Witch of Wall Street,” she worked alone and amassed a fortune worth billions in today’s money.

    Gambling Man — How Masayoshi Son came from obscurity to be the richest man in the world, lost a fortune, and made it back. 

    The New Tao of Warren Buffett — “Cryptocurrencies are like rat poison squared.” That quote alone was worth the price of admission! 

    Damn Right! — This biography of Charlie Munger gives great advice, like the importance of avoiding self-pity.

    Warren Buffett Speaks — “… we like great companies with dominant positions, whose franchise is hard to duplicate, and has tremendous staying power or some permanence to it.“ This series of quotes from Buffett break down his investment philosophy.

    Memos from the Chairman — Ace Greenberg was the chairman of Bear Stearns in its heyday. If they had stuck to his simple advice of serving the customer and being frugal, they’d still be around today.

    Common Stocks and Uncommon Profits — This slim volume from 1958 is one of Buffett’s top book recs. Much of his approach of investing in high-quality companies at reasonable prices comes from this book. 

    eBoys — How Benchmark hit eBay and became one of the top firms in Silicon Valley.

    Talent — Tyler Cowen and Daniel Gross explain how to spot top talent. 

    Grinding It Out — Ray Kroc’s account of building McDonald’s.

    Thicker than Water — An inside account of the fall of Theranos.

    The Default Line — Go behind the scenes as the EU deals with the fallout from the financial crisis. I ordered this book from England years ago. Since then, I’ve read it three times, often near market peaks.

    The Courage to Act — Ben Bernanke’s account of steering the Fed through the financial crisis. 

    Boomerang — Michael Lewis tours the crisis-struck West in the wake of the financial crisis.

    Population Plunge Meets AI Revolution

    One Billion Americans — Matthew Yglesias explains that for the United States to stay number one, we have to grow our population big time.

    Empty Planet — Exploring the fertility crisis from Korea and Japan to the developing world. 

    The Technological Republic — Alex Karp’s call to build in the real world, not just the world of bits. 

    Homegrown — The story of Oklahoma City bomber Timothy McVeigh. One surprising fact: had the GM plant in his hometown not closed, he might have become a normal factory worker like his father and grandfather. 

    Janesville — When Janesville, Wisconsin’s GM plant closed, the town never truly recovered. AI is going to cause a lot more Janesvilles.

    Industrial Society and Its Future — The manifesto of the Unabomber. I find most of what Kaczynski says to be off base, but it does get me out of the techno-optimist echo chamber. 

    Breakneck — Dan Wang explains that although China is catching up to the West, its future is bleak. 

    Politics

    Original Sin — How Joe Biden and the Democrats lost the presidency. 

    2024 — How Trump retook the White House.

    Biotechnology

    The Code Breaker — Walter Isaacson’s account of how Jennifer Doudna and Emmanuelle Charpentier discovered CRISPR gene editing.

    A Crack in Creation – Doudna’s first person story of discovering CRISPR.

    Sacred Hoops — Phil Jackson recounts leading the Bulls to one championship after another using meditation and mindfulness. 

    Where Men Win Glory — How Pat Tillman gave up NFL millions to fight and die in Afghanistan. 

    Fiction

    Treasury for Children — A beautiful storybook with wonderful animal illustrations. I particularly like the story of Bonny the horse. Fun for all ages!

    The Exchange — John Grisham brings back Mitch McDeere! I plan to read more light fiction like this in the new year. It’s a great way to relax.

    Wrap-Up

    Trying to get better as an investor feels like being in school.

    Reading, note taking, listening to the greats. I feel the same excitement I felt during the best parts of my education.

    There’s no better way to learn than books. Grab one off this list and tell me what you think!

  • I was laying on the couch, eyemask on, earplugs in, trying to imagine the next great startup. “What about collecting data from factories to train robots?” Well, I found it…

    It’s called Cortex AI

    Cortex AI: Training Industrial Robots

    Cortex AI gathers video from factories and workshops. It sells that data to robotics companies to help train robots. 

    To teach robots to work in factories, we’re going to need tons of video. But there isn’t much video available from real facilities.

    Robotics companies are forced to use data from labs and simulations. That data isn’t realistic.

    Several startups collect video from inside people’s homes to feed to AI models. Cortex’s approach is different — they are focused on industrial data. 

    Getting Real World Data 

    Cortex AI is building the marketplace for industrial robotics data. 

    Factories and workshops make money by providing video. In businesses with tight margins, this additional revenue stream is huge! 

    Robotics companies love this data because it’s from the real world. This lets their robots learn faster.

    The Perfect Founder

    The founder, Lucas Ngoo, has one of the most impressive backgrounds of anyone I’ve invested in.

    Lucas was the co-founder and CTO of Carousell, a marketplace for used goods in Southeast Asia. Carousell was backed by Sequoia India and is valued at $1.1 billion. 

    Lucas’s background is perfect because he’s already built a super successful marketplace. 

    Carousell is in a very different market — used goods vs. AI data. But a marketplace is a marketplace, and Lucas has seen this movie before. 

    What About Jobs?

    Robots will replace some humans in factories. This is inevitable.

    Imagine if we had refused to adopt tractors because they would replace farm workers. Almost everyone would still be doing backbreaking labor on farms for very little money.

    Technological progress has some cost in the short run. But in the long run, we are way better off. 

    Wrap-Up

    I’m delighted to have a little slice of Cortex AI’s recent seed round!

    It’s rare that I see a fantastic founder building in just the right market. When I do, I’m itching to place a bet. 

    This investment showed me the value of daydreaming. 

    I learned this technique from studying Cyan Banister and James Simons, two top investors. They’re both known for spending hours just thinking.

    I spent hours imagining big opportunities. When I saw Cortex AI, I knew I’d found what I was looking for. 

    If I hadn’t prepared my mind by daydreaming, I might have missed it! 

    If you work in robotics, check out Cortex AI’s data and take your system to the next level. And if you run a factory, look into selling your data! 

    This is the last post of the year. I’ll see you guys on Monday, January 5th.

    Merry Christmas and Happy New Year! 🎄🥳

  • Ever feel lost on how to improve your product? Here are three ways to get the customer feedback you need…

    1. Send an Amazon Gift Card. Customers are busy. Getting them to respond to your messages is hard.

      But there’s nothing wrong with a little bribery!

      If you offer folks a $50 Amazon gift card for a 15 minute feedback call, you’d be surprised how many people will do it.

      Be sure that you put the offer right in the email subject line so they’ll see it.
    2. Ask for Feedback Inside the Product. Why not meet your customers where they already are: inside your product?

      Put a little link inside it that lets them offer feedback. Pop-ups are annoying — just put the link on the side or bottom of the screen.

      Just let them type free text. Don’t make them answer a long survey.
    3. Send Some Swag. If you have their address, why not send them a little company swag?

      Make sure it’s something high quality that they’ll actually want to use. A well-made coffee mug, a butter soft hoodie, or a high quality hat.

      Make your logo discreet. You don’t want to turn people into a billboard.

      Inside the package, you can put your phone number. Tell them you’re really looking forward to hearing their thoughts about the product and you want to make it better for them.

      When you give someone a gift, they want to reciprocate. It’s human nature. 

    Wrap-Up

    Sending gift cards and swag to a few dozen customers will probably only cost you a couple thousand dollars. The feedback they give you could be worth millions.

    Your existing customers have the secrets you need to get your company to the next level. You just need those customers to share them with you. 

    If you have a little money kicking around, using it to get customer feedback is one of the best investments you can make.

    How do you get feedback from customers?

  • Here’s how a typical angel investor loses $250,000:

    • Start with $250,000 bankroll. 
    • Gives $100k to founder. 
    • “We’re launching soon!” 
    • A year later, still not launched.
    • “We need more money.” 
    • Gives another $100,000 to founder.
    • Six months later, product still not launched.
    • “We’ll be ready to launch any minute! We just need a little more money.”
    • Angel is afraid of losing his $200,000 investment.
    • Gives founder the last $50,000.
    • Company goes bust.
    • $250,000 vaporized.

    This is what happens for most angels. They only invest in one company. The founders are not technical, and the product never launches.

    Their money goes up in smoke. 

    Here’s how we can do better… 

    Focus on Launched Products

    I never invest in a software product that’s pre-launch. 

    Especially with vibe coding, anyone can launch a product. If they haven’t done so, this tells me everything I need to know about them. They are not motivated or skilled. 

    At least 90% of startups will never launch a product. If I simply remove those startups from consideration, I take 90% of the potential zeros out of my portfolio. 

    Invest in Builder Founders

    Why don’t products launch? Most of the time, it’s because the founders don’t have the necessary skills to build a product.

    The rule that YC uses is to back teams of two to four founders, at least half of them technical. That’s as good a rule as any. 

    Every day I see early-stage startups with a dozen people on the team. Few, if any, are builders. What the heck do these people do?

    Focus on people who can actually build software. It’s awfully hard to have a pizzeria if nobody knows how to make pizza. 

    Spread Your Bets

    We’ve eliminated the non-builders that are never going to launch a product. But even for builder founders that manage to launch and get some customers, the startup game is brutally difficult.

    So we need to do the opposite of the typical angel — we need to spread our bets.

    Take that $250,000 bankroll. The better way to divide that is 50 bets of $5,000 each. 

    If I make between 30 and 50 investments, I should be able to hit at least one unicorn. But if I only make one investment, my odds of hitting a unicorn are practically zero.

    In our business, returns come from a handful of companies. You have to hit a unicorn in order to get a good return.

    Diversification gives us an opportunity to hit something big.

    Wrap-Up

    If you’re thinking about getting into angel investing, be aware that you could lose every cent.

    You worked hard for this money. Don’t hand it to just anybody. 

    Focus on builder founders with launched products. Spread your bets widely.

    If you do that, you have a chance to beat the odds and nail a killer investment.

  • The Allen Institute for AI recently released its most powerful model ever: Olmo 3. Olmo is cheap to train, making it perfect for anyone training their own model. 

    Olmo 3 is 2.5 times more efficient to train than Llama 3.1 based on GPU-hours per token. Olmo is also much more transparent than other models.

    Most so-called “open source” models, like Llama or DeepSeek, are really just “open weight.” They give you the weights, but they won’t show you how they trained the model (“model flow”) or give you the training data.

    Olmo is 100% open. 

    I popped up Olmo 3 on OpenRouter this morning. Let’s see what this thing can do!

    Round #1: Researching Marketplace Startups

    Yesterday, I was researching the background of a really incredible founder. He co-founded a unicorn marketplace. 

    This got me thinking…how many people in the world can say that? 

    Olmo gave a solid estimate on the number of unicorn marketplace startups and the number of co-founders. Its best guess is that there are a couple hundred people in the world who have co-founded a billion-dollar marketplace. 

    Olmo’s response was solid, but it didn’t cite any sources. This makes it hard to rely on the answer.

    Competing models like DeepSeek have nailed sourcing. At this point, it’s table stakes.

    I’m giving this round a C. 

    Round #2: Learning About the Fiber Buildout

    We are in the midst of a massive AI buildout. Big tech companies are spending a fortune on GPU’s, data centers, and training data.

    How big can this get?

    For comparison, I asked Olmo to tell me about the fiber buildout in the 1990s. This time, I used its “Search” function to see if we can get some citations in the response.

    Olmo estimates that Telecom spent $50 billion in the US on the fiber build-out. But it doesn’t cite any sources, so it’s hard to know if these figures are accurate. 

    I got vastly different numbers from Grok and Gemini, both around $500 billion. 

    Again, the lack of sourcing makes Olmo’s outputs a lot less useful. I’m giving this round a C as well. 

    Round #3: Planning My Christmas Trip

    I’m beginning to feel a little sorry for Olmo. So, I decided to give it something a little easier.

    I’m flying back to Wisconsin on Christmas Eve. The airport is likely to be packed to the gills.

    Can Olmo give me some tips for surviving the chaos? 

    Olmo reminded me that my Global Entry membership lets me use the TSA Pre-Check line. I forgot all about that!

    That was a very helpful tip that could save me hours. I’m giving this round an A!

    Wrap-Up

    Overall, Olmo 3 scores a C+ in my testing. 

    Olmo is definitely not the most powerful AI model out there, or even the most powerful open source model. 

    But the outputs are decent, and it’s very cheap to train. 

    Try using Olmo in your application and see if it gives you the outputs you need. If so, it may make sense to switch.

    The most powerful model isn’t always the best choice for your application. Sometimes, cost matters. 

    Have you tried Olmo?

    Have a great weekend, everyone!

  • Foreign founders raising money in America make the same mistakes over and over. Here are 5 things you need to get right to raise in the US…

    Humility Doesn’t Play in America

    “We’ll see how it goes.”

    I was at a demo day in NYC a while back, listening to a young British founder pitch her startup. This is how she ended her pitch.

    Not good.

    “Do you think Elon Musk says, ‘We’ll see how it goes?’” I asked her. “You want to be confident. We’re going to dominate!”

    Americans are brash and unequivocal. “We will,” not “we will try to.”

    Foreigners are tentative and shy. Folks like that don’t get funded.

    When you’re pitching Americans, be bold. It may read as arrogant in your home country, but not here.

    Formality Makes You Sound More Foreign

    “Mr. Santora, thank you for responding to my message, esteemed sir. We are raising the sum of $1,000,000 and would like to meet to discuss.”

    American business culture is informal. Don’t call anyone Mr., Mrs., Sir, or Madam.

    Just call them by their first name. 

    I used to work for Judy Faulkner, the founder of Epic. We called her Judy. 

    If you can call a multi-billionaire entrepreneur by her first name, you can certainly call me Francis! 

    When you’re too formal, your pitch comes off as strange and foreign sounding. You want to sound as natural as possible.

    Focus on the Right Investors

    Even if you nail the boldness and informality, you could still fail to raise from American investors by focusing on the wrong people.

    Focus on investors that invest in your country. 

    Take me for example. I invest in the U.S., Canada, UK, Ireland, Australia, and New Zealand. Anything outside of that is pretty much a no-go.

    Those are markets I know in places where I can speak the language natively. So, it makes sense for me to focus there. 

    Not sure what countries an investor focuses on? Look at their website or LinkedIn.

    Pitching people who don’t invest in your country is a waste of time. 

    Delaware C Corp Is a Must

    Every day, I see great foreign startups with the same dealbreaker: they’re not incorporated properly.

    If you want to raise venture capital from Americans, you need to be a Delaware C Corporation.

    Almost every American investor requires it, especially institutions. It gives us a predictable legal environment.

    You don’t need to have a physical presence in Delaware. You never have to set foot there. It’s just the company’s legal home.

    If you’re incorporated in a different manner, you can do a procedure called the Delaware flip. Get a lawyer’s help on this. 

    Forget About Foreign Tax Credits

    When British founders contact me, they’re always pitching something called EIS. EIS is a tax credit program for British investors.

    Never bother pitching this to Americans. 

    We don’t know what it is. We don’t benefit from it.

    So, it doesn’t matter to us.

    Wrap-Up

    People from all over the world want to pitch American investors. Many countries have few, if any, angels and VCs of their own.

    I love investing in foreign startups! I’ve got one in Canada, two in the UK, and even one in Amsterdam.

    But if you want to raise money from Americans, you’ve got to do it our way.

    Be bold. Be informal. Pitch the right investors. Get incorporated properly. And forget EIS.

    If you can get these five things right, your chance of raising money from Americans will go through the roof.

    Have you tried to raise money from Americans? What was it like?

  • I tried to sell software to an AI simulator. I wound up crushing my quota and getting promoted! My biggest lesson: you can’t sell to every buyer the same way. 

    Every day, I’m evaluating founders’ sales skills. The founder is the first salesman for the startup.

    If they’re good at it, the company can scale fast. If not, the company will struggle. 

    But there’s one little problem: I’ve never actually done sales myself. So when Jason Lemkin from SaaStr launched Vaporsell.ai, I had to try it! 

    Here are three buyers I sold to and what I learned…

    John: The Busy Buyer

    “Give me your value prop in 30 seconds.”

    John is on his way to the airport and doesn’t have much time. He wants me to get straight to the point.

    Some might consider John rude. But I live in the NYC area, so I’m used to people being blunt.

    I actually sold to John pretty successfully. I just had to keep my responses short and specific.

    When a response required more time, I offered to send more detailed information to his email. In the end, I was able to close a large contract.

    I actually like buyers like John. Getting to the point makes things easier for both of us.

    But John wasn’t my favorite customer. No, that’s Gavin… 

    Gavin: The Gullible Buyer

    “That’s amazing! What else can this software do?”

    Gavin is like a breath of fresh air. He’s already really excited about the product. 

    It would be hard to screw this sale up. Everything I say, Gavin likes. 

    If you have PMF/market pull, you’ll meet a lot of Gavins. You’ll be the leader in your area and people will be predisposed to buy.

    What worked for me here was to not overthink it. 

    Gavin wants the product. Just give quick and cheery answers to his questions, and soon he’ll be signing on the dotted line. 

    I wish they were all Gavins! But then where’s the challenge, right?

    Speaking of challenge, it’s time we meet Sarah. 

    Sarah: My Most Hated Buyer

    “I don’t buy software from amateurs.”

    I was feeling pretty good about my sales skills. Then I met Sarah. 

    Sarah is a VP at a major startup. Her deal could have put me way over my quota. I needed this!

    But Sarah is the buyer from hell. She’s prickly, rude, and super technical.

    Even though she was fake, I could feel my cortisol rising.

    I would try to answer her questions, but she would always say my answer wasn’t specific enough. My technical sophistication simply didn’t match hers.

    Try as I might, I was never able to sell to Sarah. She actually called me an “amateur” and hung up.

    I’m glad I never have to speak to this jerk again!

    But Sarah taught me something useful. I don’t need every single buyer.

    I never sold her a dime’s worth of software, but I still crushed my quota. Take that, Sarah! 

    Wrap-Up

    Using Vaporsell gave me new empathy for anyone in sales. Selling is friggin’ hard. 

    My biggest takeaway: you can’t sell to every buyer the same way.

    Some buyers, like John, want a quick rundown. Others, like Sarah, want you to go deep. 

    In the end, the main thing that helped me was practice. 

    This makes me want to prioritize founders that have experience in sales. They’ll be better at closing customers and at fundraising, too! 

    Try Vaporsell and improve your sales skills. It’s better to lose a fake deal than a real one!

  • I tested the top models from Grok, Gemini, and ChatGPT head to head this morning. Gemini won, showing incredible power at research and sourcing.

    The last month has seen some amazing releases from the top AI labs. xAI released Grok 4.1 Thinking, Google released Gemini 3.0 Pro, and OpenAI dropped GPT 5.2.

    This got me thinking…if I ran the same prompt through all three, who would win? 

    I gave the models a tough question that requires a lot of research: what is causing the massive population decline in Latin America?

    This region is seeing some of the fastest decline in birth rate in recorded history. I’m fascinated by the fall in child-bearing across the world, and Latin America is on the front lines.

    Let’s see what these models can find out… 

    Grok 4.1 Thinking: Lightning Fast, But Imperfect Interface

    Grok’s response was very informative, searching over 100 sources in seconds. It still amazes me we can do this!

    Grok does a great job of explaining the causes of Latin America’s fertility decline. 

    Governments made it easier for teen girls to access long-acting contraception like hormonal implants. The huge decline in teen pregnancies is a major factor pushing down the fertility rate. 

    I wish Grok would cite its sources in line with the facts they support. This would make it easier to verify the info.

    But when I do click through on Grok’s sources, they check out. Its research abilities are strong, even if the formatting of the citations isn’t perfect. 

    I’m giving Grok an A. 

    Gemini 3.0 Pro: Superb Research, Clear Presentation

    Gemini does an awesome job of citing sources in line with the facts they support. I can easily click the link and verify the information. 

    When I open the source page, Gemini even highlights the information it relied on. This is next-level! 

    Gemini also gave a great table showing the fertility rates across Latin America. 

    A lot of the information is the same as Grok’s. But the better sourcing puts Gemini over the top. 

    I’m giving Gemini an A+! 

    GPT 5.2: Respectable, But Watch Out for Sourcing Problems

    ChatGPT’s latest model gave a strong response, starting with overall fertility numbers and then digging into causes. It noted that three-quarters of Latin American countries are below replacement, an important fact I didn’t see in Grok or Gemini’s response. 

    But in terms of sourcing, ChatGPT was the worst of these three models. 

    It cites multiple sources for a particular fact, but only allows you to click through on one of them. This seems to be a quirk in the interface, but it makes it hard to verify the information. 

    I’m giving GPT 5.2 a B+.

    Wrap-Up

    Gemini wins this contest, scoring an A+ versus an A for Grok and a B+ for GPT 5.2. Gemini gave a well-reasoned and very useful response, supported by the best sourcing I’ve ever seen.

    But what strikes me most is how good all these models are! Even the laggard, GPT 5.2, would have been considered science fiction two years ago. 

    I pay for Supergrok and I’m sticking with that for now. Gemini is slightly better, but not enough to switch.

    Try all these models and see what they can do. Then, let me know which one is your favorite!

  • I ran OpenAI’s new GPT 5.2 through a three round test. It still scores below Grok and Gemini.

    Some of GPT-5.2’s responses are excellent. But the quality of its answers are inconsistent. 

    Let me show you where this model excels and where it falls short… 

    Round #1: Learning About Needle Biopsies

    Tomorrow, I’m meeting with a company that’s working on cancer diagnostics. They’re going to make needle biopsies easier.

    Can GPT 5.2 help explain how needle biopsies work? 

    GPT 5.2 gave a fantastic answer here. It clearly explained exactly how needle biopsy and MRI work together. 

    It also noted that some needle biopsies are done together with CT scans, which I did not know. When I clicked through on the citation, I found a high-quality source from the National Institutes of Health.

    I’m giving this round an A+! 

    Round #2: Investigating AI Market Research Startups 

    This afternoon, I’m meeting with a startup doing AI market research. It creates synthetic audiences to test marketing content.

    So I asked GPT 5.2 for an overview of the startups in this area. I asked for a ton of information, including product features and the amount of venture capital they’ve raised. 

    GPT 5.2 crushed it here, giving a great summary and lots of detail on the leading startups. When I clicked on citations to verify how much funding these startups raised, the information checked out. 

    I’m going to give this round an A+ as well! 

    Round #3: CoachGPT 

    For our third and final round, I asked GPT 5.2 to help me with my workouts. 

    My goals for weight training are hypertrophy and longevity. What exercises should I try?

    GPT 5.2 gave a nice response with useful pictures. It recommended some exercises I’ve never heard of, like the “dead bug” for core strength.

    But it did not cite a single source. So, it’s hard to know how good this information is. 

    Are these really the best exercises for my goals? Or are they just random things GPT 5.2 came up with?

    I also would like to see GPT 5.2 respond with some videos, not just still images. When it comes to learning an exercise, there’s nothing like a video.

    I’m giving this round a C. 

    Wrap-Up

    Overall, GPT 5.2 earned a B+ in my testing.

    It seems to be tuned toward white-collar work, like investing and medicine. OpenAI alluded to this in their announcement.

    But when I use it for anything else, GPT 5.2 is pretty weak. It wasn’t very helpful in helping me plan a workout.

    Our goal is Artificial General Intelligence. AGI would give great answers to all sorts of questions.

    GPT 5.2 doesn’t do that. 

    OpenAI’s latest model isn’t bad, but it’s still behind Grok and Gemini. Grok scored an A in my testing and Gemini scored an A-.

    No wonder Sam Altman called the code red. OpenAI may have started the AI revolution, but today, it’s falling behind. 

    Have you tried GPT 5.2?

  • I just used an incredible new AI education app called Oboe. If you want to learn how to design great software, read on… 

    Oboe just launched in September. The founder, Nir Zicherman, also founded the podcasting tool Anchor. 

    Oboe can spin up a course on any subject you want, using AI.

    Several of the most successful people I know studied psychology. So today, I used Oboe to give me an intro to psych…

    A Slick UI, a Powerful Application

    Oboe’s design is world class. 

    All I had to do was write a one-sentence prompt: “Give me a basic introduction to psychology.” Suddenly, an entire course appeared!

    The course is structured in brief units that take just a couple of minutes to read. The material is clear, engaging, and useful.

    You can even hear the lessons as a podcast! 

    This is awesome if you’re busy doing dishes or working out. The podcasts are so good it’s very difficult to tell they’re AI.

    Time for a Pop Quiz

    After reading through the first lesson, I thought to myself, “I need some flashcards for this. I wonder if there’s an AI app to make flashcards.” 

    Oboe read my mind! 

    Just below, Oboe embedded some flashcards in the page. Click on them, and you see the answer.

    Putting this flashcard application into the course automatically is absolutely genius product design. As soon as I saw this, I knew Oboe could be really big.

    How Oboe Can Improve

    One problem Oboe has is sourcing.

    Take the section on research methods in psychology…it links to only one source. 

    When I click on the source, all I get is an outline of a psychology course. I don’t see any information on the topics in the course, so it’s hard to tell whether Oboe’s information is accurate or not.

    This is a new product, so I’m not expecting it to be perfect. But better sourcing would be a great way to improve.

    I’d also like to see flashcards and quizzes in every single section. Right now, Oboe includes them in some sections but not others. 

    Wrap-Up

    Overall, I’m giving Oboe an A. 

    If it could do a little better with sourcing and quizzes, I’d bump that up to an A+. I’d also love to see an iOS app. 

    Oboe is incredibly powerful. It gives every single person free access to a great education on any subject.

    Think about all the kids stuck in rotten schools. 

    Maybe their teachers are terrible, their classmates unruly. But if they can somehow get access to the internet, they can learn with Oboe.

    Oboe is already better than most of the teachers I’ve had, even at good schools. 

    I made it halfway through my course this morning. I’m looking forward to finishing it soon!

    If you want to take my Intro to Psych course on Oboe, here’s the link. We can learn together.

    Have a great weekend, everybody!
