Element was founded by the team behind the Matrix protocol, a groundbreaking project redefining how the world communicates through open, secure and decentralised messaging.

The mission behind Matrix is simple but powerful: make messaging as open and accessible as email. That means giving people and organisations the freedom to choose where their data is hosted, enjoy truly private conversations, and stay in control of their communications.

Today, Element helps major organisations run Matrix securely at scale, from the French, German and British governments to international institutions like NATO and the UN.
