Open House 2025 is the first ever ClickHouse User Conference! It is a premier one-day event for ClickHouse users, contributors, enthusiasts, and customers, hosted in the heart of San Francisco on 29 May. For those unable to join in person, the event will be streamed to multiple locations worldwide, ensuring everyone can be part of this global gathering.

We plan to stream selected sessions to New York City, London, and Singapore. More details on the exact timing and location of these live streaming events are upcoming.

At a glance the agenda and initial speaker lineup is above, and we’ll be announcing more details as the event shapes up. It will include:

• Insights from company founders
• In-depth technical sessions from builders and practitioners
• ClickHouse users sharing their stories
• Demos and AMA

Yes, in-person training will be offered on an optional basis in San Francisco on May 28 2025, the day before the main event.
