London-based AI video platform Synthesia has raised a $200m Series E round led by Google Ventures, valuing the company at $4bn.
Other new investors in the round include Evantic, the VC firm founded by former Sequoia investors Matt Miller, and Hedosophia. Existing investors NVentures (Nvidia’s VC arm), Accel, Kleiner Perkins, NEA, PSP Growth and Air Street Capital also participated in the round.
Founded in 2017, Synthesia develops video generation software that creates avatars of people for internal and external company communications.
The new round takes the company’s total funding to over $500m. Its last round was a $180m Series D in January 2025, which gave the company a $2.1bn valuation.
Synthesia said some of the funds raised would be used to develop a new category of conversational AI agent products, designed for organisational learning and upskilling.
“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,” CEO Victor Riparbelli said in a statement. “Market opportunities like this do not come along often.”
Last year, Synthesia was reported to be in talks with software giant Adobe to be acquired for about $3bn. Adobe and Synthesia did not reach an agreement, reported the Information.
As part of the new round, Synthesia will allow employees to sell secondary shares.
