Nvidia and Alphabet’s VC arms have backed British AI startup Synthesia in a $200 million funding round, amid a surge of private investment in promising young tech companies seeking to capitalize on the AI boom.

The round sees Synthesia hit a $4 billion valuation and was led by Alphabet’s GV, with participation from Evantic, Hedosophia, Nvidia’s NVentures, Accel, New Enterprise Associates (NEA) and Air Street Capital. It nearly doubles the price tag the startup hit a year ago, when it picked up $180 million in funding, and a valuation of $2.1 billion.

Synthesia develops video generation tools for enterprises to be used for internal and external communications.

Victor Riparbelli, Synthesia’s cofounder and CEO, in a statement, that the funding round was “about scaling” its vision of AI reducing the cost of content creation, and AI video providing “a better, more engaging way for organizations to communicate and learn.”

“We see a rare convergence of two major shifts: a technology shift with AI Agents becoming more capable, and a market shift where upskilling and internal knowledge sharing have become board-level priorities,” he added.

As part of the raise, Synthesia will facilitate an employee secondary share sale in partnership with NASDAQ at a $4 billion valuation.
