Why Google & NVIDIA Back Startup Synthesia’s US$4bn AI Push

AI video-platform startup Synthesia has secured a US$200m Series E round, lifting its valuation to around US$4bn.​

The raise is led by existing backer Google Ventures (GV), alongside continued participation from existing investors NVentures – NVIDIA’s venture capital arm – as well as Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, First Mark and MMC Ventures.​

Synthesia says the fresh capital underscores investors’ confidence in its long-term roadmap and ambition.​
Co-founded in 2017 by former Joe & the Juice employee Victor Riparbelli, who remains CEO, the company has grown into a leading player in AI-powered video creation.

Discussing the funding, he says: “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 organisations to communicate and learn.

“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.”

Synthesia has also revealed plans for an employee secondary sale, arranged in partnership with NASDAQ at a US$4bn valuation, to give long-standing team members liquidity while allowing them to retain a stake in the company’s future growth.

Enterprise learning and workforce development

The capital will be directed towards building a company focused on transforming how employees learn, with an emphasis on areas such as enterprise learning and development, knowledge sharing, product marketing and sales enablement.

Leveraging its realistic video avatars, Synthesia says its next decade of growth will centre on a shift from one-way content to interactive learning experiences.

The company plans to develop conversational agents designed primarily to support organisational learning and workforce upskilling.

The CEO adds that this is a “unique point in time where technology enables agents that can truly understand and respond” at a time when “enterprises are under unprecedented pressure to reskill and upskill their workforce”.

UK Chancellor of the Exchequer Rachel Reeves says: “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.”

The start of a success story 

Synthesia reports that early user feedback has been “highly positive”, with organisations noting higher engagement levels and quicker knowledge transfer than with traditional formats.

The platform is now used by more than 90% of Fortune 100 companies to improve visual communication and enterprise skills development.

Vidu Shanmugarajah, General Partner at Google Ventures, says: “We’ve been partners with Synthesia since the Series B and have long believed in Victor and the team’s vision.

“Today, we’re even more convinced that Synthesia has the product, the team and the traction to become the category leader in AI-powered learning experiences.”

Synthesia says that in light of the strong user feedback, it remains focused on delivering category-defining products that help organisations transform how they learn and share knowledge.

The company is committed to pursuing this mission responsibly, safely and sustainably to ensure long-term growth.
