About the Event
The BIGGEST builder after party around AI Engineer Fair is coming to San Francisco.
Hosted at Notion HQ with Composio, Notion, OpenRouter, Modal, Braintrust, Parallel Web Systems, Cursor THE AI Engineer After Party brings together 300 AI builders, founders, researchers, and operators for a high-energy night after the main event.
We’re taking over Notion’s lounge and café space for a premium happy hour experience with DJs, bartenders, drinks, light bites, and the most exciting AI builder crowd in town.
This is not another conference happy hour.
This is where the AI builder stack comes together after dark — models, compute, evals, agents, web systems, workspace, and the people building what comes next.
Come for the conversations. Stay for the energy. Leave with the room everyone will be talking about.
