3 lessons for founders from my time at Zo Computer

what I learned building at the frontier

Exactly 3 years ago, I decided to become a founder. My personal motivation was not wealth, but personal transformation, during a time when living on the edge was clearly more interesting than staying still.

I left a cushy managerial job at Stripe in 2023, where I’d worked for over 8 years. I was fortunate to build Terminal as the first engineer, and it continues to be one of my proudest achievements.

When I started a company with perceptnet, inference was all the rage, so we dreamed up a DAG-based platform. The idea was in the right ballpark, but only modestly successful after a year, so we shut it down and returned to the drawing board. We spent 6 months throwing spaghetti at the wall, then started building Zo. The manic excitement that emerges during that zero -to-one is truly the spice of life. I was drunk on Fable. Then I was drunk on Sol. I felt unstoppable.

During the depths of my AI psychosis, I had moments of mania: 3 all-nighters one week, on top of repeated mornings waking up too early with a head full of prompts. In the fog of war I began to see how the way I worked over the last 3 years was unsustainable. I’ve always suffered from an overactive brain. I always feel like the end is in sight, just around the corner, and if I grind just one more time I’ll see the light.

While I was reflecting on my burnout, an idea entered my head and I haven’t been able to ignore it. I realized I’ve been building tools to enable builders for 11 years. But in my heart of hearts, I’ve always been a musician, a creator, an artist, a bootstrapped indie hacker. I asked myself the hard question. When will I stop building the tools, and start building my own dream?

I can feel it in my bones that we’ve reached a bright new frontier with model capability. Just as I felt ahead of the curve last year, spending way too much money on Cursor, I have this edge today that most builders don’t have yet.

I’ve started building a software factory. Good software with a non-zero market size is a store of value. If you have a good process for producing good software cheaply and without much supervision, you should scale it up, produce a ton of good software, and figure out distribution so you can harvest the value.

One viable path to the one person $1B company is to create 100 $10M companies.

Three lessons for founders

As I close my chapter as Zo’s cofounder, I want to share three lessons, one for each of the past few years:

1. You must cultivate superhuman speed

The first big lesson, acquired through pain, is that there’s a real insanity that is required to win. Real personal sacrifices must be made. A mad cranking of the OODA loop is required, iterating as fast as humanly possible.

2. You must cultivate true sight

The second big lesson, acquired through fear, is that there is a certain boldness that comes only from true sight. Seeing clearly means seeing your weaknesses without stubbornness or pride. Seeing the world in harsh relief. Killing your darling beliefs and philosophies without preciousness. Putting yourself out there repeatedly without fear. Leaning into discomforts – in order to see them clearly, and outgrow them as fast as possible.

3. You must transform yourself

I firmly believe most people are capable of much more than they know – they simply haven’t pushed themselves anywhere near the jagged frontier. Reality is malleable, and your self (which defines your reality) is the most malleable of all.

That’s all for now. Until next time,

PS) Here are some lyrics to Grey Gardens by Casey MQ that feel especially poignant today:

In the grey gardens
The deeper I go
Into the crowded room of people I know
In the grey gardens
Where everything grows
It's such a long way home

Falling like Alice did into something so cavernous
Banality becomes something like stars into your heart

Reach into me
Take everything
Remembering is not opposite of forgetting
It's like the lining

Peeling back my skin and leave no traces of my body
When I sleep to drеam my orchestra plays theme of soul and spirit pouring out

Rеach into me
Take everything
Remembering is not opposite of forgetting
It's like the lining
