Ulysses in Monocle’s November Issue.
nice 👍
The 2026 American Dynamism 50 is here: our annual list of 50 companies, from within the a16z portfolio and beyond, building for America's future. This year's theme is Production is Deterrence. "America's ability to prevent conflict depends on what it can build, how fast it can deliver, and how long it can keep going." A new generation of defense companies is moving from prototypes to full-scale production, and the industrial base has to keep pace. This year's list is organized around three pillars: 1. Systems: the drones, ships, missiles, aircraft, and spacecraft that deter conflict. 2. Factories: the plants, tools, and software that build them. 3. Inputs: the materials and power they're made of and run on. Get all three right, and the impact reaches well beyond defense, to skilled jobs, revitalized communities, and the supply chains behind energy, housing, and everyday goods. Meet all 50:

I am hiring some interns to do more work like this. We want designers, photographers, editors, marketers, and creatives of all kinds. More details here:
UlyssesTV - Episode 1: Jack fixed the robot. The Ulysses team is on the water testing every day. More time on the water means faster learning and a better product for our customers. Engineers like Jack make those days go swimmingly well.

Aditya is one of the most rigorous thinkers I know. This is sure to be an incredible talk.
This Friday, I’ll be giving a talk on the historical case for the resurrection of Christ. Several years ago, I began looking into the historical evidence as an atheist to prove that Christianity was nothing but a therapeutic superstition. What I found completely changed my life. Over the course of a year, I spent nearly every waking moment reading whatever I could find on the subject. My entire life was suddenly reorganized around answering this one question: did Jesus Christ actually rise from the dead? There was a time when I thought this question was too ridiculous to even consider. But looking back, it was by far the most important question I've ever asked. If you're interested in learning more, check out the link to the event page below. All are welcome to join regardless of religious background or lack thereof.

Excited to start showing some more behind the scenes at Ulysses. We are just keeping it pretty raw and passing a camcorder around the office. We went future hires to have a pretty unvarnished view on what it’s like to work at the ocean company. We hope you enjoy!

they should make a Good Will Hunting but for hard tech where the office cleaner turns out to be a fucking sick machinist spinning parts at night
Hamilton is BACK Thank you @OsGuinness for a brilliant lecture.
Wore my Navajo earrings & cowgirl boots to see @OsGuinness give an excellent lecture on faith’s role in freedom. Thank you for another lovely evening Hamilton Society, @Willob @pratheology @fedpoasts

Ulysses has achieved a new milestone: the Mako has clocked over 1,000 active hours in the water. The ocean is hard on machines. Salt, pressure, currents, impact, corrosion. Time in the water is where reliability is earned, and lessons are learned. Every hour with Mako has given our team more operating experience, more data, and more opportunities to improve the system. Thank you to all our customers for trusting us to solve problems for them at sea.

Justin is building an incredible company that will let us speak with plants. What a beautiful sci-fi technology. This totally changes agriculture, horticulture and so many areas of plant science. I’m so excited to see what they build.

1/ Today we’re unveiling Bombadil, @electricplantco's foundation model that reads the electrical signals of living plants and turns them into a continuous view of their physiology. Trained on 7M+ hours of plant electrical signal across 125+ species. That makes Bombadil the most species-diverse model of directly recorded electrical biosignals in existence. The animal equivalent would be one model that reads the brainwaves of blue whales, horseshoe crabs and fruit flies.

Another takeaway after three years of building a company is that the returns to just "being a good person", and not acting transactionally, are higher than I expected. There are so many transactional, boring, and at times immoral people in the tech industry that if you act with sustained warmth, authenticity, humor, and integrity, great gifts will be laid before you. White pill.

Jimi Hendrix was once asked “What’s it like being the greatest guitarist that’s ever lived?” To which he replied “I don’t know. Ask Rory Gallagher.”
Every year, Rory Gallagher came home to Cork to play Macroom, Ireland’s first open-air rock festival. In 1978, he made it legendary. He rolled up in a car, grabbed his battle-scarred ‘61 Strat, ran straight up the steps with no soundcheck, and tore into “Shin Kicker.” Pure rock and roll.

Wow. This is going to be beautiful. The world needs more beautiful Catholic art like this.
One of the coolest things we’ve ever been a part of. It changed my life radically, and I think it’s going to change the world. Check out the trailer for Pétros Ení. Coming soon to Hallow.

Most children (and adults) can identify 100+ logos and nearly 0 native plant species This is not healthy for society Native wildlife roots us in our place and we should treat it with such reverence If we do not root ourselves in the land it is very easy to lose our ourselves

.@willob on how Guinness gave us Student’s t-test “I studied math in college, and one of the tests from that is the Student’s t-test. This is how you derive either the standard deviation if you know the mean, or the mean if you know the standard deviation from a small sample, less than 30. This was a problem at Guinness because one of the biggest predeterminants of the quality of a pint of Guinness is the amount of lipids or fats in hops. So, they were having to take up hundreds of hops to see is this a high-quality batch or not? And they were losing a few percent per batch. And that means a lot when you’re in the high-volume, low-margin food-and-beverage industry. So William Sealy Gosset had to publish under a pseudonym. That's why it's called the Student's t-test.”

Will O'Brien of @UlyssesInc on why today's young founders are more Steve Jobs than Jeff Bezos: "The founders look very different, right? It's like the kind of rah-rah, smoking, go to church on Sunday, maybe a bit louder, working typically on hardware rather than software." "It's like a different motivation. There is seemingly more of a kind of a spiritual reason to why people start their businesses." "I often think of there being head and heart type founders, where Jeff Bezos is the canonical head-based founder... 'What would be the best thing to sell on the internet? Oh, books are good because you can move them easily.'" "Steve Jobs being the canonical heart-based founder, the bicycle for the mind, the hippie on acid... And I think this era of founders are way more oriented on the heart-based." "A lot of us were very, I think, impacted by something like COVID. A lot of us are typically in our later 20s now, but were in college or something like that when it happened. It kind of made me feel a little bit cheated." "We were forced to be in the digital world, so we feel cause to impact the physical world... Or maybe we're just more of a product of the times that we're in." @Willob on Cheeky Pint

Ulysses has its own aquarium full of live seagrass, fish, shrimp and other little critters. This aquarium has been built from the ground up to be self-feeding. Each trophic layer feeds the next with seagrass at the base. It’s a beautiful embodiment of our mission of ocean stewardship in action.

Fun fact: when you google “lads drinking Guinness” I’m the first result
Who would have thought that it took a 29-year-old Irishman to put the teetotalers of San Francisco in their place I have been training to competitively drink Guinness for decades I was born for this Sorry @elonmusk
