Mackenzie Burnett is the co-founder and CEO of Ambrook, an all-in-one bookkeeping, invoicing and payment tools that help family‑run businesses improve margins and stay independent.

This week, Abrook announced that it's raised $29 million, including a $26.1 million Series A from Josh Kushner at Thrive Capital and Figma CEO Dylan Field at Field Capital.

In our conversation, we talk about building a product at the intersection of American Dynamism and the American Dream, how farm economics work, how she's grown her business to over 2,500 customers, and where the company plans to go from here.

Mackenzie mentions a few essays:

- 2022 Founder's Letter

- Moving past skeuomorphic AI by Michael Akilian

- Could AI Actually Help Rebuild the Middle Class? by David Autor

Sari Azout is a former VC, the founder of Sublime, a friend, and a writer whose work I've long admired. We actually co-wrote the first piece I ever wrote on crypto about a company called Fairmint.

Sari is one of the most thoughtful and tasteful people on the world wide web, something that comes across in her writing, in the product she's building at Sublime, and even her background in this video. While a lot of people are talking about what AI means for humans, Sari is one of the few people I actually want to talk to about that topic.

A few weeks ago, she gave a talk she titled "Becoming unLLMable" at the Sana AI Summit in Stockholm, and then she summarized it on her Substack: Becoming unLLMable

Because of the format in which she originally presented these ideas, we did this one a little differently. To kick us off, Sari gives the presentation that we gave in Stockholm, and then we dig in on questions I had and things I've been thinking about.

It's characteristically Sari: optimistic but practical, grounded in facts but unafraid to imagine, and informed by her perspective as someone actually using AI to build a product and voice that stands out in a sea of undifferentiated slop.

We discuss a bunch of though-provoking ideas, my favorite of which is that average is now attainable by everyone, which means to stand out, you need to be way better than average. She is a case study on how to do that.

At the end of the conversation, Sari makes a few recommendations.

Cate Hall is the CEO of ⁠Astera⁠, one of my favorite organizations and the new home of my friend ⁠Eli Dourado⁠, and one hell of a writer.

If you've noticed the word "agency" popping up all over the place, you have Cate to thank. Her 2024 essay, How to be More Agentic took the internet by storm and brought agency into the zeitgeist, where it has remained and grown. Now, she's even writing the Book on Agency, which you can pre-order here.

On the first episode of Hyperlegible with Tina He, when I asked who people should read more of, Tina recommended Cate. So I was excited to see Cate drop a new essay that felt like it was written at me (and I think will feel like it was written at you, too) called Crossing the Cringe Minefield:

Crossing the Cringe Minefield

When we want to improve ourselves or our station in life, she argues, we start with the things that come naturally, the easy wins. They don't work. Then, we try things we don't love but don't hate. Those don't work, either.

Finally, we're faced with a choice: give up, or do the thing that feels deeply, incredibly uncomfortable, the thing that makes us cringe. That's where the answer normally is, because the cringe is a sign that we've left that area of ourselves under-developed."

This means," Cate writes, "that existential cringe is actually a signal pointing you to where you can make the most progress quickly."

We all have something we want to get better at. And we all have something that makes us cringe to even think about.

In this conversation, I ask Cate to guide us (OK, me) through the Cringe Minefield. We sprinkle in a little agency, too, of course.

There hasn't been a Hyperlegible with more laughs or more depth. I hope you learn as much about yourself as I did, and come away as ready (as you'll ever be) to face your cringe.

At the end of our conversation, Cate makes a couple of recommendations:

Wander raised $50+ million in a Series B led QED and Fifth Wall. The fun part is, Wander did it by throwing out a lot of what we discussed in the first Wander Deep Dive — which, at the time, I said was the absolute right way to do things — and growing insanely fast while maintaining its high quality bar. I started doing these Deeper Dives, following up on companies I’d written Deep Dives on in the past to understand what I got right, what I got wrong, and what we could learn from both, in March, with a Deeper Dive on Primer. I gotta admit, I was a little smug: Primer was doing great, in large part because it had gone more vertically integrated, which is exactly my thesis on how these things should be built. “And if you want to fix K-12 education,” I wrote, “you need to build schools.”Welp… over the past two years, Wander shut down the REIT I praised, went asset-light, grew from 13 to more than 1,000 locations, grew GMV 6x over the past 18 months, and is onboarding over $1 billion worth of real estate monthly. And while growing, its NPS has actually ticked up to 85. Being wrong and learning is why I do the Deeper Dives! If companies could be built as cleanly as I can write an essay, I’d be a billionaire. You’ve got to play the game; the lessons emerge from the messiness, and from following the best companies as they evolve. So today, I'm talking to Wander CEO John Andrew Entwistle about what we both got wrong and how Wander has gotten the important things right. You can read the full Deeper Dive at Not Boring.

Reggie James is a founder, the author of the Product Lost substack, one of the most original thinkers I know, and one of my top choices to be the Creative Director of America.In this conversation, we discuss his latest piece, A tale of two Vaticans (or, OpenAI building an unholy spirit), which you should read before listening, or after.

No one but Reggie could have written this piece, which is the highest praise I can give to a writer. It combines his deep knowledge of the history of Silicon Valley, his Christianity, and his willingness to "critique the gods."

And it gave me an excuse to cover a topic I've been wanting to talk about for a while -- the rise of Christianity and the search for meaning -- with the best person I know to have that conversation with. We go deep and wide in this one. I hope you enjoy it.

Mike Solana is the founder and Editor-in-Chief of Pirate Wires, one of my favorite publications on the whole internet and the only one I read every day.

You’ll hear this about a lot of our guests, because this is why I do Hyperlegible, but Mike is one of the best writers doing it today, one of the few whose name in my inbox gives me a little dopamine hit. His writing is unlike anything out there. He’s not afraid to tackle tricky subjects, not afraid to form his own opinion, not afraid to be earnest, and he writes the cover off the ball in a way that feels entirely his.

The piece we discuss today, Golden Age, is pure Solana. He starts by copping to having a lovely time in Disney World, before taking us on a tour of Walt Disney’s vision to build a whole futuristic city in the Florida swampland. He talks about why China has been able to execute on Disney’s vision better than America has, and what it would take to build a modern version, what he calls Golden City, a place where houses are cheap and rare earth metals are processed.

Go read it: https://www.piratewires.com/p/golden-age

It makes me nostalgic for this future, and after listening to our conversation and reading Golden Age, I hope you’ll add your voice to the small but mighty chorus calling on President Trump to just give Solana the federal land in California he needs to build this thing.

We talked all about this piece and much more, live from The Manhattan Lab in New York City, where Matt Marlinski was nice enough to let us record.

Nobody on the internet writes about all of the complexity involved in actually building things -- from homes to jet engines -- better than Brian Potter, the author of Construction Physics.

I am a huge fan of Brian's writing. I use it as a reference for a lot of my pieces. I once tweeted, "Construction Physics is a national treasure and the president should give Brian Potter a medal or czar job or something." So I was thrilled to get the excuse to talk to him about a bunch of his essays by talking to him about this one specific one, 50 Things I've Learned Writing Construction Physics.

Here's the one overarching theme he's discovered writing over 600,000 words in Construction Physics: "Things are always more complicated than they seem. Simple explanations very rarely exist."

We discuss that and other lessons by digging into pre-fabbed and manufactured homes, jet engines, gas turbines, windmills, nuclear reactors, batteries, Nobel Prizes, skyscrapers, and even Titanium.

Just reading that list, you can probably tell why I like Brian's writing so much. He writes in-depth about all of the topics I love, and I learn so much from him each time.

What impressed me most is just how humble Brian is. He knows 1000x more about this stuff than I do, but when he's not entirely certain of an answer, he says so. That's probably in part due to his background as a structural engineer, and in part a response to the lesson that everything is more complicated than it seems.

I hope you learn as much from our conversation as I did, and that you go back and read everything he's written.

To get you started, here are some of the essays we discuss and that Brian recommends, both his stuff and others'.

In this timely conversation, Conrad Bastable joins Packy to break down his epic essay Forsaking Industrialism and explore why the West has abandoned manufacturing while China built a world-beating industrial platform over decades. Read it here for the full experience: Forsaking Industrialism

Conrad has been planning this essay for months, and he couldn't have dropped it at a better time. It's a comprehensive look at what China got right and what real reindustrialization would mean.

We dive into how EU regulations inadvertently benefited Chinese manufacturing, why tariffs alone can't solve America's industrial challenges, and what it would take to rebuild America's manufacturing capabilities.Conrad explains the concept of "platform economies" that China has mastered, why capital markets naturally push against long-term industrial investments, and the uncomfortable trade-offs between principles and prosperity that nations must navigate.From electric dirt bikes to BMW's battery dilemma, this wide-ranging discussion offers a fresh perspective on the most urgent debate in America.

Pseudonymous writer Parakeet joins me to discuss her viral essay "Skittle Factory Dementia Monkey Titty Monetization."

I first heard about Parakeet a couple weeks ago when I saw half of my Twitter feed and half of my Substack Notes feed sharing her essay, including a bunch of people I wouldn't expect to share an essay with "Monkey Titty" in the title. I read it immediately, and saw why. Parakeet describes universally applicable ideas with the color turned up to 11 so they stick.

We explore the "dementia personality" - how our core thought loops shape who we are and might one day define us. Parakeet shares insights from working at a dementia facility, explains her Skittle Factory metaphor for personality (and researching Skittle Factories), and reveals her unconventional productivity hack that's transformed her writing output.

We talk about her writing process, gifs, why more people should read George Orwell's Politics and the English Language, and what she learned from her once-half-paralyzed dance teacher. Plus, hear the bizarre true story behind the "Monkey Titty" portion of the essay title and why Parakeet believes everyone should re-read Atlas Shrugged as an adult.

On Episode 004 of Hyperlegible, I speak with Alex Danco. It was a treat. Alex is on my Mount Rushmore of internet writers. When I’m writing well, his writing has probably had an influence on mine. 

In this conversation, we talk about his new essay, which is an update to some of his older pieces, Scarcity and Abundance in 2025. If you want to understand how to think about everything that’s going on right now as a result of AI in a really thoughtful, grounded way, read the essay.

There’s so much here. What did Clayton Christensen get wrong? How does tech make things that, contra disruption theory, make things that are both cheaper and better? Is Apple in trouble? Will the vibe coding apps maintain their growth and revenue? What has become scarce? 

We talk about the shift from Code as Capital to Code as Labor, Tokyo zoning regulations, Red Queen’s Races, whether this time is actually different this time, why big company AI products suck because they’re trying to squeeze everything out of their existing assets, Steve Ballmer Trutherism, and why crypto + agents might actually be a thing. This summary just scratches the surface. Just listen. 

At the end, Alex gives some great essay recommendations:
