Why we made this

An hour a week, for the rest of your life.

Catalyst is a quiet thing. This is the short version of why.

The last fifteen years have produced a strange paradox. We have never had more access to ideas, and we have never been worse at sitting with them. The library is open all day; nobody is in it. Most of what gets called learning, on a phone, is the digital equivalent of pacing the bookshelves — looking at spines.

Catalyst is the opposite of that. It is a small, deliberate room with a chair in it, and a book open on the table.

The bet is this: that the thing you want is not more content. It is structure. It is to know that, today, you have a Tuesday-sized thing in front of you, and that it ends. That when you close the app, the work for today is done, and tomorrow there is another thing, and the day after, another, and on the seventh day, the path closes and you are different.

Most apps are designed to capture attention. We wanted to build one that deserves it.

The shape of the bet

The Stoics — Marcus, Seneca, Epictetus — were unfashionable for most of two millennia. Then, around 2015, something changed. Ryan Holiday's books found an audience. The Stanford encyclopedia spiked. A generation of people who had nothing in common except a vague sense that things were faster than they should be, started reading philosophy on the train. Not because anyone told them to. Because the alternative was a feed.

That same generation has not been served well. Book-summary apps gave them the takeaways without the thinking. Productivity apps gave them streaks and badges. Meditation apps gave them their breath. Nobody, as far as we can tell, gave them what they actually came for: a serious, patient, well-written companion for the long project of becoming.

That's the gap. That's what Catalyst is for.

A book on a topic — read aloud, in seven days.

The shape of the product

We chose audio-first because the moment of opportunity is on the way somewhere. You are walking, or driving, or doing the dishes. You are not in the chair, ready to read. You have ten minutes, and they will pass either way.

We chose seven-day paths because seven days is the smallest unit of time in which an idea can change shape. Less, and you have a tweet. More, and you have a course you'll never finish.

We chose to write the lessons by hand because the alternative — an LLM, telling you about Stoicism — is what we made this app to compete with, not to be.

And we chose against streaks, badges, leaderboards, push notifications, social feeds, and recommended-for-you trays, because every one of those is a tax we did not want to ask you to pay. The deal is: you give us ten minutes a day. We give you, in return, the closest thing software can give to a quiet room with a book in it.

If that's what you came for, we built this for you.

A short list of things we believe

What we make — and don't.

We make

  • Lessons that take ten minutes to read and a lifetime to use.
  • Audio narrated by a person, not a model. A real human voice, with breath in it.
  • Paths with an end. You finish them. You move on. You take what mattered with you.
  • One quiet nudge a day, on a day of your choosing.
  • A library that's yours — keep it on cancellation, forever.
  • An app that closes itself when the lesson ends.

We don't make

  • Streaks, badges, leaderboards, fire icons.
  • AI-summarised books. The summary is the work.
  • Push notifications you didn't ask for.
  • A feed. Anywhere. For any reason.
  • Recommended-for-you trays at the bottom of every lesson.
  • Anything that would make us proud at a growth conference.
Who's making it
RM
Robin — founder, based in the Netherlands.
I built Catalyst after a colleague asked me to read a 140-page book before a meeting. I didn't have time for it, so I summarised it instead — ten-minute reads over three days. I walked in able to hold the conversation, and the knowledge had landed without the friction of reading every page.

Before Catalyst I studied Mechanical Engineering and work as a Manufacturing Engineer. I also founded a Leadership Institute, where I first got serious about the gap between information that exists and knowledge people actually absorb.

Lessons are commissioned per topic from practitioners who teach the material for a living — psychologists, classicists, decision-theory researchers — and reviewed twice before audio.

The quiet room is open.

Ten minutes a day, on a topic you chose. The rest is on us.
