Where curiosity meets connection.
The Door is a living movement where curious learners discover how money and business connect with nature, how technology works with big ideas, and how every question opens new doors to understanding our connected world.
It started with an uncomfortable question.
Spring 2022. A simple observation that wouldn't let go: we have never had access to more information — and never felt less fed by it. Endless feeds, endless courses, endless takes. And still that quiet sense of drifting rather than understanding.
Einstein described curiosity as a delicate plant that needs freedom above all else to flourish. That image became the starting point. Not a platform that tells you what to learn — a space where curiosity is allowed to grow wild again.
Because a door asks nothing of you.
A door is the most familiar thing in the world. It doesn't demand a qualification, a level, or a plan. You can crack it open just a little. Peek through, if there's a window. Test the air before you step across. And you can close it again — no one asks why.
That is exactly the relationship we want you to have with knowledge. Every door stays open, and every door stays optional. Curiosity survives invitation; it dies under obligation.
Knowledge doesn't live in silos. Neither do we.
Climate change is an economics problem. Technology is an ethics problem. The real breakthroughs happen where disciplines touch — so The Door is organised as eight interconnected chambers rather than eight separate subjects.
The seams run through people too.
What is true of knowledge turns out to be true of the people carrying it. Someone studies criminology and wants to help others see what is being done to them online. Where does she belong?
Partly each. Wholly none. And no list of occupations has a name for what she actually wants to do.
No list of work has a name for everyone.
She is not an exception. There will be many like her, and the honest thing to say is that no map of work will ever hold them all — ours included. When you don't find yourself on it, that gap is real, and it is not a gap in you.
It runs the other way as well. What you learned reading a room in a busy restaurant is not restaurant knowledge. It is knowing when someone isn't okay, and it travels — into care, into teaching, into moderating a room full of strangers online. We are more interested in where your experience carries across than in the label it arrived under.
Which is why we never file anyone under one chamber. You are allowed to belong in several places at once, and to be something no one has named yet.
Six values, and one of them is fragile.
To nurture humanity's most powerful force — curiosity — by creating spaces where people freely explore the interconnected nature of knowledge, transform questions into discoveries, and build the collective wisdom our world desperately needs.
Our vision is a global movement of interconnected learning communities, built on one conviction: curiosity — not credentials — is humanity's greatest renewable resource.
The curious mind behind The Door.
Twelve years coordinating semiconductor ecosystems teaches you one thing above all: the breakthrough is almost never inside the discipline. It happens where materials science meets circuit design, where process technology runs into system architecture — at the seams. And it taught the opposite lesson too: how much potential gets lost when people only ever talk within their own silo.
As AI and automation began reshaping entire industries, one question kept returning: in a world overflowing with information, why do so many of us still feel disconnected from real wisdom? The answer wasn't more data. It was better connections — between ideas, between disciplines, between people.
The name was in my passport the whole time.
My family name is van Deurzen. Deur is the Dutch word for door. Decades of signing that name, and I never once looked at it.
‘Translate’ it into English and you land on Doorzon. Which happens to be a word here: the Doorzon family is the most ordinary household you can picture — the standard house, the standard week, curtains open, nothing to see.
We were the opposite of that. So for years that is exactly what we called ourselves. It ended up as the name of our wifi network. It was a joke, and the joke was a contradiction: we used the word that meant the opposite of us.
Years later the thing I was building needed a name. It took me embarrassingly long to notice what I had been carrying around in my own passport.
A door is not a destination. It is what you walk through to find out what is on the other side.
I have no special talent. I am only passionately curious.
That line has been in my WhatsApp status for years. Not as decoration — it is the closest thing I have to an explanation of myself.
I am not the cleverest person in any room I have worked in. Twelve years in semiconductors cures you of that idea quickly. You sit across from someone who has spent his whole career on one process step, and you learn what real depth looks like. It is not you.
But the work asked for something else. As a key account manager, and later as senior sales manager, you have to understand how a thing works — not to the level of the engineer, but far enough to feel it. Far enough to be a proper gesprekspartner, which is a Dutch word we do not really have in English: the person on the other side of the table who can actually think with you, instead of waiting for his turn to talk.
That means asking. Constantly. Why is it built this way. What breaks first. What would you change if nobody stopped you.
In most places where people learn, that is not treated as a strength. It gets called distraction. Or a lack of focus. Or not knowing what you want. I believed that about myself for a long time.
The Door is built on the opposite assumption.
The longer version — why I built this, and what I got wrong first
The question
A spring break spent wrestling with why information abundance and wisdom scarcity can exist side by side. The Door began as an answer to that.
Where fields meet
Semiconductor ecosystem coordination — learning first-hand that innovation lives at intersections, and that siloed thinking quietly caps what people can become.
Exploration over certainty
A family decision to choose the open question over the safe answer.
Travelling as learners, not tourists
Setting off around the world to understand how different cultures hold their most meaningful questions — the same curiosity The Door is built to protect.
The door is open
Eight chambers, the Alliance, and SEED — where you follow your own trail and meet the work that lives where you are walking. Still looking for the people and organisations who recognise that what comes next depends on thinking across boundaries.
