The Matrix Conference 2026

Building a safer network, together

Join Jim from the Matrix.org Foundation Trust & Safety team, as he walks through the progress the ecosystem has made in building a safer network, and invites you to join us in building the future of safety on Matrix. Jim is joined by special guest Juliet from ROOST, and you'll hear about their tools Coop and Osprey. We'll talk about how matrix.org is using those tools, and how we're making them more accessible for Matrix servers. Jim will also talk about Reporting v2, a flagship project for the Foundation Safety team, and how you can help.

Jim Mackenzie

Hi! I'm the VP of Trust & Safety for the Matrix.org Foundation, and I try to bring a calm optimism to making Matrix a kinder, safer place. I've been with the Foundation since 2021, and I work on policy and process, tooling and techniques for Matrix.org and Matrix as a whole.
