Together AI is a San Francisco-based AI acceleration cloud that lets developers and enterprises train, fine-tune, and run open-source generative AI models on a high-performance GPU platform. Backed by $533M+ from General Catalyst, NVIDIA, Salesforce Ventures and others, it has become one of the most prominent challengers to the closed-model status quo.
Vipul Ved Prakash is a serial entrepreneur and technologist who co-founded Together AI, an AI acceleration cloud platform valued at $3.3 billion after a $305M Series B in February 2025. Previously, he built Topsy (acquired by Apple for $200M+), co-founded Cloudmark (acquired by Proofpoint), and created Vipul's Razor - one of the internet's first collaborative anti-spam systems. A self-described cypherpunk with a table-tennis past, Prakash has been dismantling bottlenecks - from spam to closed AI - for over two decades.
