Join
Enter Nullhaus.
Joining takes about a minute and costs nothing. It puts you in the network, on the list for session invitations relevant to your field, and gives you full access to everything we publish: no fee, no tier, no sales call afterward. There’s nothing to sell you, so no one will try.
What happens after you join
1. Confirm your email
One link, one click. It keeps our network honest and lets us reach you about sessions that actually match your field. Nothing else rides along.
2. Get session invites and the library
New field guides, briefings, and recorded Assembly sessions land in your inbox as they publish. When an Assembly or Roundtable opens up in your field, you’ll hear about it.
3. Engage: attend, ask, contribute
Show up to what you’re invited to. Ask the real question, not the safe one. At a Roundtable, bring the actual problem, not the version you’ve already smoothed over for an audience. Standing in this network is earned through engagement, not accumulated by sticking around.
4. A few are invited into The House
Past a certain point, for a small number of members, something further opens. Who, when, and how: we don’t say. If it’s meant for you, you’ll know.

What it costs
Nothing. Nullhaus is a nonprofit: membership is free, invitations are free, the library is free, no matter where you live, who employs you, or what you can pay. This isn’t a teaser rate and there is no tier above it. It’s the whole model, and if it ever stopped being free it would stop being Nullhaus.
Privacy & data
We collect what a real network needs to function and nothing beyond it: your name, email, professional field, and a record of what you attend and read, so that invitations reach the right people for the right themes. We don’t sell your data, and we don’t hand it to third parties for marketing. Write to contact@nullhaus.org at any time to see what we hold, correct it, or have it deleted, and we will not make you ask twice.
Frequently asked
Is there a catch, since everything is free?
No. Nullhaus is a nonprofit, funded independently of membership fees or advertising. Free means free: no upsell, no premium tier lurking behind this one, and no moment later where we ask for a card.
Will joining get me spam or constant emails?
No. You’ll hear about relevant sessions and new publications, not a daily newsletter and not third-party offers. Every email we send carries an unsubscribe link, and it works on the first click.
How long before I might get invited to a session?
There’s no fixed clock. Some members hear from us within months. For others the right theme takes a while to come around, because the room is built for the subject rather than the subject chosen to fill a room.
I’m a student, or new to the field. Can I still join?
Yes. Membership and the full library are open at any experience level. Session invitations tend to favor practitioners with current, hands-on standing in a topic, but the primers and field guides are written with newcomers specifically in mind, and they are the same material the practitioners read.
What if I only want the free content and never attend a session?
That’s a perfectly good way to use Nullhaus, and plenty of people will. Joining gets you the library either way. Nothing about keeping it requires showing up to anything.
