GV leads $200m round, Synthesia valued at $4bn

Corporate video automation is entering a new phase as London start-up Synthesia secures $200 million at a $4 billion valuation. The deal doubles the company’s value since January and reflects how fast enterprises are moving from static decks to on-demand video.

According to Forbes, the round was led by Google Ventures, backed by Alphabet, with participation from Nvidia, Atlassian Ventures, Kleiner Perkins, PSP Growth, First Mark and Accel. Coming on the heels of a $180 million Series D in January, the latest financing lifts total funding for Synthesia to more than $500 million.

The platform turns text prompts into narrated clips, offering a library of human-like avatars that can deliver more than 140 languages with striking naturalness. Enterprises use it for training, sales enablement and marketing, drawing customers such as SAP, Merck, Heineken, Zoom and Bosch. With adoption reportedly exceeding 90% of the Fortune 100, Synthesia has become a default tool for teams that need video without cameras.

While the broader contest in text-to-video includes heavyweight efforts like OpenAI’s Sora, the London company is staking its advantage on business use cases rather than entertainment. Its chief executive, Victor Riparbelli, has emphasized building tools for presenters and human clones in corporate content, aligning with procurement, compliance and localization demands. That focus distinguishes Synthesia from platforms that court cinematic ambitions or consumer creativity.

Strategic attention has followed. Earlier this year, Adobe’s venture arm invested an undisclosed sum and later returned with a reported $3 billion acquisition offer, which was rejected. By turning down a sale, Synthesia signaled confidence that recurring enterprise demand and improving model quality can support a far larger outcome.

The new capital arrives as multilingual, policy-compliant video becomes baseline infrastructure delivered by software rather than studios. Backers such as Google Ventures and Nvidia are betting that advances in compute and generative research will keep lowering costs and widening the market. As Europe leans into standards around safety and watermarking, a UK hub anchored by Synthesia offers a preview of commercialization at scale — a reminder that the next era of corporate video will reward those who make creation invisible, reliable and trusted.
