When an AI system causes harm, where should responsibility sit: with the developer who built it, the organisation that deployed it, or the person who used it? This panel brings technical and policy perspectives together to find where accountability breaks down in practice, and what each side can learn from the other.

We produce original research that speaks across disciplinary lines, and we create spaces where researchers, engineers, policymakers, and the broader public think together about what is being built and what it means.

We are not a policy shop that treats the technology as a black box, and we are not a lab that treats governance as someone else's problem. We sit in the space between, and we think that space is where the most important work will be done.

Maria Federica Martino Lena
Co-founder

Studied philosophy and public policy at LSE and philosophy at King’s College London. Works on AI governance, value alignment and AI safety, including accountability and responsibility in AI systems.

We work across AI safety, AI governance, and the philosophy of artificial intelligence, and we treat them as one field rather than three. Our first research outputs are in development. We will say more about specific projects when they are ready.

A regular programme of talks, seminars, and roundtables in London. Most sessions are open to anyone paying attention to what AI is becoming.

Public Talks

Open events with researchers and practitioners from across AI safety, governance, policy, and philosophy.

Seminars

Smaller recurring sessions built for depth and disagreement. Working discussions rather than lectures.

Roundtables

Closed-door sessions bringing a small group of researchers, policymakers, and practitioners around one problem.

The future is not a forecast. It is a design problem. And design problems require more than designers. They require everyone who will live with the result.
