About

A society for the people who build and defend technology.

Nullhaus began from a simple conviction: the most serious practitioners deserve a place that is serious in return — free of vendors, noise, and spectacle. Cybersecurity is our foundation, but our scope is the whole of modern technology: AI, software, cloud, data, and whatever comes next. We are nonprofit, online-first, and global by design. What we build belongs to the field.

Two gatherings a month

The first brings together world-class leaders — practitioners at the top of their disciplines — for conversation that doesn’t happen on public stages. The second is a working session: organizations bring a hard, unsolved problem to the room, and the room goes to work on it. No pitches. No performance. Only the problem.

Open by principle

Knowledge compounds when it is shared. Nullhaus publishes its education openly — freely available to anyone serious enough to use it. The inner circle is private; the learning is not.

Founders

Nullhaus was founded by Okan Yıldız, a cybersecurity leader, and co-founded with his wife — built as an institution meant to outlast its founders.
