Synthesia secures $200 million at $4 billion valuation to expand Nvidia-backed AI avatars for corporate HR and training

Synthesia has raised $200 million at a $4 billion valuation to develop interactive AI video avatars focused on sales training, recruitment, and internal HR use. The London startup, backed in this round by GV, Nvidia, Accel, Hedosophia, and Evantic Capital, is shifting away from consumer-facing media toward enterprise training and communications. Led by CEO Victor Riparbelli, the company reports annual recurring revenue exceeding $100 million and is testing new question-answering avatars with clients including Microsoft, UBS, and Ford.
