UK-based Synthesia has raised $200 million in a Series E funding round, reaching a valuation of $4 billion and nearly doubling the $2.1 billion mark the AI video platform achieved just a year ago.
The round was led by existing investor Google Ventures, with participation from Evantic, the venture fund founded by former Sequoia partner Matt Miller, and Hedosophia. Additional backing came from existing investors including NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates, PSP Growth, Air Street Capital, FirstMark, and MMC Ventures.
The funding represents continued investor confidence in enterprise-focused AI companies that have moved beyond using the technology for only experimentation to demonstrating clear revenue generation and commercial traction.
Synthesia crossed $100 million in annual recurring revenue in April 2025 and is on track to reach $200 million this year. The company also reported quadrupling agreements worth more than $100,000 over the past 12 months, indicating that enterprise clients are committing larger budgets to the platform.
The platform is now used by more than 90% of Fortune 100 companies, with clients including Bosch, Merck, SAP, and Microsoft. The company serves over 1 million users across 60,000 businesses.
What Synthesia Does
Founded in 2017, Synthesia builds AI-powered tools that allow organizations to create training videos, internal communications, and marketing content using AI-generated avatars instead of traditional production methods.
The technology has found particular success in corporate learning and development, where companies need to produce training content at scale across multiple languages and departments. Organizations use the platform for employee onboarding, compliance training, internal communications, and customer support materials.
Synthesia’s Plans for the New Capital
Synthesia plans to use the funding to develop more advanced interactive video tools, moving beyond one-way training content. The company is working on AI agents embedded in video avatars that can answer questions, simulate role-play scenarios, and provide tailored explanations to employees during training sessions.
This shift toward interactive experiences represents an evolution from static video content to dynamic learning tools that can adapt to individual users in real time.
“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,” Victor Riparbelli, Synthesia’s co-founder and CEO said in a statement.
“This funding round is about scaling that vision,” Riparbelli continued. “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. We intend to build the defining company at that intersection, by combining our know-how in AI video with our ability to build and integrate AI technologies into products and services that solve real business needs.”
Alongside the funding round, Synthesia will facilitate an employee secondary sale in partnership with NASDAQ at the $4 billion valuation. The process will allow employees to sell shares at the same valuation as the Series E while giving the company more control over the transaction.
Chief financial officer Daniel Kim said the secondary sale is designed to give employees access to liquidity while allowing Synthesia to remain focused on long-term growth as a private company. The structured approach helps avoid the informal, varied-valuation secondary sales that can sometimes create tension among shareholders.
Market Context
The funding arrives at a time when investor enthusiasm for artificial intelligence remains strong, though with increasing focus on companies that can demonstrate actual revenue rather than potential applications.
While some investors have grown cautious amid ongoing debate over whether heavy spending in AI is inflating a market bubble, the Synthesia’s Series E funding round suggests capital continues to flow toward companies with defined revenue streams and enterprise adoption, especially when it comes to the development and application of AI.
Vidu Shanmugarajah, general partner at Google Ventures, highlighted that enterprises are moving beyond asking whether they should adopt AI for learning and communications to focusing on how fast they can do it and how deeply they can integrate it into their workflows.
The company’s growth also highlights the strength of London’s AI sector. At a $4 billion valuation, Synthesia joins a small group of European AI companies that have managed to scale beyond regional relevance.
