Tavus is a San Francisco-based generative AI personalized video platform — backed by Y Combinator with $24.2 million in total funding including an $18 million Series A in March 2024 led by Scale Venture Partners with a $6.1 million seed led by Sequoia Capital — providing enterprises, sales teams, and developers with APIs and SaaS tools for creating hyper-personalized AI videos at scale using voice and face cloning technology, serving major customers including Salesforce and Meta with 49 employees. Founded in 2020, Tavus's proprietary Phoenix model requires only 2 minutes of video training data to clone a person's voice, facial movements, and speaking style — enabling the creation of thousands of fully personalized video messages from a single human recording session, with each video appearing as if filmed specifically for each individual recipient.
