Synthesia, the London-based AI video platform, has confirmed it has raised $200m (£146m) in a Google Ventures-led Series E round that has landed it with a $4bn valuation.
Reports of the investment were circulating late last year after sources close to the situation spoke to Forbes. The company on Monday confirmed the details.
Known for its AI avatar platform used to generate human-like speeches and videos based on script prompts, Synthesia has been growing rapidly in recent years.
First founded in 2017, Synthesia reached a unicorn valuation of $1bn in 2023 off the back of its $90m Series C round. Since then the company has secured round after round of investment from major names including Adobe, Accel and NVentures – the VC arm of NVIDIA.
The latest funding round as well as Google Ventures included participation from Evantic, a fund founded by a former Sequoia partner, Hedosophia, NVentures, Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, and MMC Ventures.
“Synthesia was founded on two core beliefs: first, that AI will bring the cost of content creation down to zero. And secondly, that AI video provides a better, more engaging way for organizations to communicate and learn,” said Victor Riparbelli, Synthesia’s co-founder and chief executive.
“This funding round is about scaling that vision. 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.”
As one of the most valuable AI companies in the UK, Synthesia has often been praised by government leaders. Last summer the opening of its new HQ in central London was attended by then technology secretary and current Business Secretary Peter Kyle and Mayor of London Sadiq Khan.
It has also participated in government-coordinated discussions on supporting the domestic AI industry.
Speaking on the new round, Chancellor Rachel Reeves said: “Synthesia is a UK success story, creating new jobs and opportunities in this country.
“It shows that by backing innovators to start, scale and stay in the UK through better access to finance and generous tax reliefs, we can turn the promise of AI into better-paid jobs and long-term growth across the UK.”
