Summary

Rockstar🎓
Top SchoolHeejin Jeong is a founder and AI leader with 11 years of experience building and shipping production ML systems, blending research rigor from a PhD at UPenn with practical product leadership. After technical roles at Waymo advancing multi-modal behavior prediction, she joined Together AI as a staff researcher and later principal AI product manager, driving core offerings like embeddings, fine-tuning, inference features, and strategic partnerships that helped scale the company to $100M ARR. Based in San Francisco, she combines cross-functional execution with deep research chops—authoring and operationalizing models, leading integrations (NVIDIA, MongoDB, LangChain), and presenting at major ML events. Unusually for a founder, she pairs high-velocity product delivery with prior academic teaching and robotics research, enabling a rare fluency across theory, ML engineering, and go-to-market.
