Why Google & NVIDIA Valued AI Startup Synthesia at US$4bn

AI video-platform startup Synthesia has raised a US$200m Series E funding round, almost doubling its valuation to US$4bn.
The round is led by existing investor Google Ventures (GV), with other existing investors NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, First Mark and MMC Ventures also participating.
The firm says the latest funding round reaffirms these investors' commitment to supporting the startup’s long-term vision.
As a former worker at Joe & the Juice, Victor Riparbelli co-founded Synthesia in 2017 and has since served as its CEO. Discussing the funding in a company statement, he said: “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.”
As part of the raise, Synthesia has also announced it will facilitate an employee secondary sale in partnership with NASDAQ at a US$4bn valuation, to provide liquidity to long-time team members and enable them to remain shareholders in the company’s future growth.
Enterprise learning and workforce development
The capital will be used to build a company that will transform how employees learn. This focuses on areas such as enterprise learning and development, knowledge sharing, product marketing and sales enablement.
Using its realistic video avatars, Synthesia says the next decade of its progress will be shaped by transitioning away from one-way content to interactive experiences. The firm is looking to develop conversational agents that are designed first and foremost for organisational learning and upskilling.
The CEO added 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”.
While Synthesia is headquartered in London, the UK’s Chancellor of the Exchequer Rachel Reeves commented: “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 says that early feedback from its users has been “highly positive” with “organisations reporting higher engagement and faster knowledge transfer compared to traditional formats”.
It is currently used by over 90% of the Fortune 100, enhancing visual communication and enterprise skills development.
Vidu Shanmugarajah, General Partner at Google Ventures, said in a statement at the time of the announcement: “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.”
The firm says that in response to the positive feedback from users, its focus remains clear on building category-defining products, help organisations transform how they learn and share knowledge.
Synthesia remains committed to doing this in a way that is safe, responsible and sustainable for long term growth.
