I first tried to explain what Soulin was in a pitch meeting in 2023. I failed completely. Three years and five product launches later, I'm still not sure I can explain it — but the system works, and this is as close as I've gotten to writing down why.

My chest tightened the first time someone asked me what Soulin was. Not because I didn't know. Because I knew they wanted me to say "it's a SaaS product" or "it's a brand agency" and the real answer — the one that lived in my ribs before my brain could organize it — was neither.

Soulin is how I survived.

That's not a pitch. It's just the truth, and the truth is messier than a landing page.

Here's the short version. I dropped out of a top Korean university, left the country with negative two thousand dollars, spent years wandering through 30+ countries with clinical depression and no credentials. I healed — slowly, mostly alone, mostly through experiments no doctor recommended. And then I started building. A hotel brand. AI tools. A content system. All solo. No team, no investors, no degree.

Somewhere in the middle of all that, I realized I'd built a system. Not on purpose. Not like a founder mapping a product roadmap. More like how your body builds scar tissue — it just does it because the alternative is bleeding.

The system had layers. How I made decisions. How I tracked what my body was telling me. How I chose what to build and what to abandon. How I structured my days so the depression couldn't eat them entirely. How I shipped things alone without burning out — or at least, how I burned out less badly each time.

I started calling it Soulin because I needed a name for the thing I was doing, and "my weird survival framework that accidentally became a business" didn't fit in a URL.

People in the startup world love the word "framework." They love it because it implies transferability — someone else can use it, scale it, productize it. And honestly, that's part of what I'm doing. The AI tools I built run my entire content operation. They could run yours too. That's the product layer.

But Soulin isn't really a framework in the way a McKinsey consultant means it. It's closer to a journal that became a philosophy that became a set of tools that became a way of living.

The layers look something like this:

The bottom layer is the body. Everything starts there. Before I make any decision — about a product, a relationship, a city — I check what the body already knows. This isn't woo. This is what 15 years of ignoring physical signals taught me. My body knew I should leave Korea three years before my mind caught up. My body knew the startup was killing me six months before I admitted it.

The next layer is freedom design. Defining what you actually want your life to look like, then reverse-engineering the work to fit it — not the other way around. I wrote about this when I dropped out: I listed everything I didn't want before I listed what I did. The "don't want" list was clearer. It usually is.

Then comes building alone. Shipping without permission, without a team, without waiting for external validation. I've built five products this way. Most of them failed. The ones that didn't became the foundation for everything I have now.

And the top layer is documentation. Writing it all down as it happens. Not curating a narrative after the fact — documenting the mess in real time. That's what this Substack is. That's what Soulin has always been.

I should be honest about something. When I say "framework," I want you to hear the air quotes. I'm suspicious of anyone who packages their life into a system and sells certainty. I've met those people. I've been pitched by those people. Their frameworks always seem to work perfectly in their case studies and never in your actual Tuesday afternoon.

Soulin isn't certain about anything. It's a documented experiment. Some of the experiments worked — I sleep now, after years of insomnia. I built a hotel brand from nothing. I taught myself to code using AI tools at 33. Some of the experiments failed spectacularly — I burned through relationships, money, and entire identities.

The documentation is the product. Not the success. Not the failure. The documentation.

If you came here because someone told you I'm a "vibe coder" or "indiehacker" or whatever the current label is — fine, those words aren't wrong. But the thing underneath the labels is simpler: I'm a person who ran out of conventional options, built unconventional ones, and decided to write it all down.

The tools I built along the way are at soulin.co. The journey that led to the tools is here.

I wrote about leaving Korea with nothing in "I Left Home With -$2,000 and No Plan" — that's where all of this actually starts, before I had language for any of it. And the moment I understood that healing and building are the same thing — that's a different essay entirely, one about standing in front of a Mark Rothko painting and choosing to stay alive. That story belongs to "The Day Mark Rothko Saved My Life."

This essay is the map. Those are the territory.

I don't have a five-year plan. I have a system that helps me survive the week, and a set of tools that help me ship the thing, and a habit of writing it all down before I forget what it felt like.

Is that a framework? Is that a business? Is that just a person trying to stay alive and build something at the same time?

I genuinely don't know. But I'm documenting the answer.
