Speaker

Amandine is COO and co-founder of Element (https://element.io), an open source, secure and sovereign communication platform built on Matrix (https://matrix.org), the open standard for secure and open communications. Element brings sovereign communications to heterogeneous organisations who can’t rely on commercial cloud offerings, let alone non end-to-end encrypted ones.
Matrix, which Amandine also co-founded, is a unique initiative aiming to democratise secure online communication and solve the problem of fragmentation in current Chat, VoIP, VR and IoT technologies. Matrix aims to create an ecosystem that makes open real-time-communication as universal and interoperable as email, and brings the power back to the user on choosing who they trust with their data and how they want to communicate. Element delivers Matrix solutions to millions of users, including NATO, the UN, the German Armed Forces, the US Navy and private companies like Mozilla.
Amandine is also a founding member of the European Open Source Academy and the lead of the Business and Impact unit within the Academy.
