Edition #6: Why Trust Is the Real Infrastructure

Every edition of this series has described a different piece of the system: how we curate who is part of it, how we design against silos, how we build a room full of the right people rather than just a full room, why we let it run without us, why we build in friction on purpose.

None of it works without one thing sitting underneath all of it, invisible, doing the actual work: trust.

Not trust as a value on a slide deck. Trust as infrastructure: the layer that makes curation mean something, and the thing that lets friction stay productive instead of turning into conflict. It's also what lets a community scale at all: once people trust the room, they stop just taking from it and start giving back to it. And you can only disagree with someone in a room if you trust them enough to still be in it afterward.

Build the Foundation First

Every community chasing density right now reaches for the same shortcut: announce the big names, open every door at once, scale the numbers before anyone can check if the thing actually works.

We chose differently, on purpose. Before we tried to bring in everyone, we made sure a small, first group of members shared the same intention as us, and started developing those relationships among them. That's slower. It's also the only version of trust that survives the community eventually scaling.

Circumstances helped too, though it didn't feel that way at the time. We opened right after COVID, and for a while it looked like nothing more than bad timing, a slowdown we hadn't chosen and couldn't do anything about. What we didn't see yet was that everyone around us was starved for real interaction, in a field that was just starting to take off. The roadblock turned out to be opportunity. But that was luck, not strategy. The strategy was building the foundation first, deliberately, and being willing to let a lucky break work in our favour instead of trying to rush past it.

People Only Trust What They've Already Seen Work

You can curate who gets in. You can design the room. What you cannot do is tell people to trust each other. Try writing "we expect members of this community to trust one another" into an onboarding email and see how far it gets you.

So we never tried. Instead, we made trust something people could watch, repeatedly.

We lead by example, our founders and general partners take their own investor meetings and high-profile conversations, out in the open, in the common space. When someone makes a real introduction, one that costs them something and gets them nothing directly back, that's not a policy. That's proof. And once people have watched that proof enough times, they start doing it themselves, unprompted.

Curation does its own quiet version of the same work. When the same relevant people keep showing up in the same room, and the conversations between them are designed to create real value rather than just happen, that repetition becomes its own kind of proof, and trust builds itself.

Trust Compounds

Once people have seen trust work, they don't just benefit from it, they start protecting it themselves. The first residents who trusted us early are the same ones curating who comes in next now. Nobody assigned them that. They just have something to lose if the room stops working the way it did for them.

It's the same reason a founder here can bring on a technical hire faster than most, or a corporate looking to pilot with an early-stage team fast instead of three months of vetting. They're not starting from zero. They're building on top of trust someone they already respect has already put in.

That's also what makes the friction from the previous edition possible in the first place. A founder can tell a direct competitor sharing the same room what isn't working in their approach, and know it'll land as help. A policymaker can push back hard on an engineer's claim in a Town Hall session, and the engineer can push back just as hard, and neither one leaves the room. None of that happens without trust already in place before a conversation starts.

We didn't build density first and hope trust would catch up. We built trust first, slowly, mostly with no one watching, and the density came after. Skip that order, and you'll end up with the room, just not the reason people stay in it.

The "AI Ecosystem Playbook" series goes behind the scenes of how Europe's densest AI ecosystem actually gets built and run. Written by Sif Björnsdottir, Head of Community & Growth at the Merantix AI Campus in Berlin, the series shows the systems and decisions behind a functioning, multistakeholder AI hub — and what it means for the founders, engineers, investors, and corporates deciding where to plug in next.
