THE AI Engineer Afterparty

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.
