Synthesia raises $200m at a $4bn valuation in a round led by Google Ventures

Synthesia has raised $200 million (£146 million) in new funding in a round led by Google Ventures, pushing the London-based company’s valuation to $4 billion and cementing its position as one of the UK’s most important intelligence businesses.

The investment marks a sharp step up from Synthesia’s previous £146 billion Series D round in January 2025, which valued the company at $2.1 billion, highlighting the speed at which the business has grown amid the global AI boom.

The latest round also attracted support from Evantic, founded by former Sequoia partner Matt Miller, and Hedosophia, as well as participation from existing investors including NVentures, Accel, Kleiner Perkins, New Enterprise Associates, PSP Growth, Air Street Capital and MMC Ventures.

As part of the transaction, Synthesia will also provide for the sale of a second employee share in cooperation with NASDAQ, which has a new value of $4 billion.

The company said the capital will be used to “build a class-defining company that will transform the way employees learn”, focusing on learning and business development, internal knowledge sharing, product marketing and sales enablement, powered by increasingly autonomous AI agents.

Founded in London, Synthesia enables businesses to create studio-quality video content using AI-generated avatars, eliminating the need for cameras, actors or production studios. The platform is now used by more than 90 percent of Fortune 100 companies to facilitate business communication, training and marketing.

The business has seen rapid growth by 2025, with annual revenue exceeding $100 million. Founder and CEO Victor Riparbelli recently revealed that the company generated $2 million in ARR in one day.

Synthesia became a unicorn in 2023 and has since accelerated its global growth, targeting markets including Japan, Australia, Europe and North America. It now employs over 500 people across offices in London, New York, Copenhagen, Amsterdam, Zurich and Munich, with most of its revenue coming from the United States.

In July, the company opened a new 20,000-square-foot headquarters in London, attended by Sadiq Khan and business secretary Peter Kyle.

Riparbelli said the funding will allow Synthesia to expand its long-term vision. “Synthesia was founded on two core beliefs: that AI will reduce the cost of content creation to zero, and that video AI provides an engaging way for organizations to communicate and learn,” he said.

“We’re seeing the convergence of two big shifts – AI-enabled agents and a market where developing internal skills and knowledge are now top priorities at the board level. We aim to build a defining company at that intersection.”

The chancellor, Rachel Reeves, hailed the move as a sign of the UK’s growing strength in AI. “Synthesia is a UK success story, creating new jobs and opportunities,” he said. “By supporting young innovators to start, scale and stay in Britain, we can turn the promise of AI into better-paid jobs and long-term economic growth.”

The funding underscores investors’ strong appetite for business-focused AI platforms and puts Synthesia at the forefront of the next wave of workplace automation and digital learning.
