Bay Area Voice AI Night ｜Stepfun X Seamate
About the Event
Voice AI Night is a Bay Area gathering for founders, builders, product leaders, and investors interested in how voice, multimodal AI, and real-time agents are changing the way people interact with products.
On July 30, StepFun and Seamate bring together people interested in how voice, multimodal AI, and real-time agents are changing the way people interact with products.
Join us for an evening of model insights, product discussion, outdoor dinner, and relaxed conversations with people building and exploring the next wave of AI products.
What's Happening
🎙️ Keynote : Voice models, from the model side
StepFun is a frontier AI lab building language, multimodal, and audio models. StepFun will share what it is seeing from the model side: where speech models are moving, what StepAudio 2.5 is designed for, and what better realtime voice intelligence could unlock for builders.
🧠 Founder panel: What It Takes to Ship Voice AI
We’ll bring together founders building in multimodal AI and Voice AI to discuss what it takes to turn new model capabilities into real products. The conversation will focus on product lessons, application-layer opportunities, and what changes when AI can listen, speak, and interact in real time.
The panel will be primarily in Mandarin 普通话, and English-speaking attendees are very welcome.
🍽️ Outdoor buffet dinner + unhurried conversations
After the main session, the conversation continues outdoors over seafood, lamb and beef, with two full hours to meet and exchange notes with other founders and builders.
Who Should Come
People building, investing in, or seriously exploring the next wave of AI products.
You do not need to be deep in Voice AI already. We especially welcome application-layer builders and people curious about where voice and multimodal interaction are going next.
Registration is approval-based so we can keep the room relevant and useful.
