Kirsten Nelson-de Búrca is a product policy manager at Mozilla, where she leads work on ads, age verification, and AI product launches globally – shaping how emerging technologies intersect with public interest and trust. With a background spanning global tech companies, startups, and the non-profit sector, she brings a rare blend of policy insight, operational know-how, and product expertise.

Before joining Mozilla, she drove global digital policy engagement for a European scale-up, HelloFresh, and at Meta she launched trust & safety product lines and political advertising transparency tools in over 100 markets. She has also advised governments, political organisations, and civil society organisations (UN entities and EU institutions) on leveraging new technologies responsibly, and navigated the fast-moving fintech startup world from a regulatory risk perspective.

A passionate advocate for responsible innovation, Kirsten speaks about the challenges and opportunities at the intersection of technology, policy, and society – with a focus on AI governance, online integrity (especially when it comes to elections, politics and social issues), and platform accountability.
