Synthesia's $4B Exit: Employees Cash In—What's Next for the AI Video Platform?
The artificial intelligence landscape continues to evolve at breakneck speed, and recent developments surrounding British startup Synthesia are a testament to this. Synthesia, renowned for its AI platform that empowers companies to create engaging and interactive training videos, has secured a substantial $200 million Series E funding round, catapulting its valuation to a remarkable $4 billion. This represents a significant leap from its $2.1 billion valuation just a year prior, signaling strong investor confidence and market traction. This surge in valuation isn't just about technological prowess; it reflects a growing demand for innovative corporate training solutions powered by AI.
Synthesia's Rise: From Startup to Unicorn
Unlike many AI startups still striving for profitability, Synthesia has carved out a lucrative niche by transforming corporate learning and development through the use of AI-generated avatars. This strategic focus has resonated with enterprise clients, including industry giants like Bosch, Merck, and SAP. The company surpassed a crucial milestone in April 2025, achieving $100 million in annual recurring revenue (ARR), a key indicator of sustainable growth and market acceptance.
The Series E Funding Round: Who's Investing?
The nearly doubled valuation was spearheaded by existing investor GV (Google Ventures), demonstrating continued belief in Synthesia’s vision. The round also saw participation from a consortium of previous backers, including Kleiner Perkins (Series B lead), Accel (Series C lead), New Enterprise Associates (NEA) (Series D lead), NVIDIA’s venture capital arm NVentures, Air Street Capital, and PSP Growth. This strong backing from prominent venture capital firms underscores the potential of Synthesia’s technology and its position within the burgeoning AI market.
Adding to the mix, the Series E welcomed new investors Matt Miller’s VC firm Evantic and the secretive VC firm Hedosophia. This influx of capital will not only fuel further development but also facilitate a significant event for Synthesia’s employees.
Employee Liquidity: A Secondary Sale Facilitated by Nasdaq
Synthesia is taking a progressive approach to rewarding its early team members by facilitating an employee secondary sale in partnership with Nasdaq. This allows employees to convert their shares into cash, providing much-needed liquidity. Traditionally, such sales occur outside of formal frameworks, often at valuations differing from the company’s official assessment. However, Synthesia is ensuring all sales are tied to the $4 billion valuation established during the Series E round, maintaining control and fairness.
“This secondary is first and foremost about our employees,” explained Synthesia CFO Daniel Kim to GearTech. “It gives employees a meaningful opportunity to access liquidity and share in the value they’ve helped create, while we continue to operate as a private company focused on long-term growth.” This move highlights Synthesia’s commitment to its workforce and its recognition of their contribution to the company’s success.
Beyond Videos: The Rise of AI Agents
Synthesia’s long-term strategy extends beyond simply creating expressive videos. The company is actively embracing the emerging trend of AI agents. These agents will enable employees to interact with company knowledge in a more intuitive and human-like manner, allowing them to ask questions, explore scenarios through role-playing, and receive personalized explanations. This represents a significant evolution in how companies approach knowledge management and employee training.
Early Pilot Results: Increased Engagement and Knowledge Transfer
Initial pilots of the AI agent technology have yielded promising results, with customers reporting higher engagement levels and faster knowledge transfer compared to traditional training methods. This positive feedback has solidified the company’s decision to prioritize AI agents as a “core strategic focus” alongside continued improvements to its existing video platform. The ability to deliver personalized and interactive learning experiences is a key differentiator for Synthesia in a competitive market.
Addressing the Corporate Training Gap
Synthesia aims to address a critical challenge faced by enterprises: keeping their workforce adequately trained in the face of rapid technological advancements and evolving industry demands. The company recognizes a convergence of two key shifts: the increasing capabilities of AI agents and the growing recognition by boards of directors regarding the importance of upskilling and internal knowledge sharing.
“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,” stated Synthesia’s co-founder and CEO Victor Riparbelli. This strategic alignment positions Synthesia to capitalize on a significant market opportunity.
A Founder-Led Initiative: Empowering the Team
The decision to facilitate a secondary sale was a proactive initiative led by Riparbelli and his co-founder, Steffen Tjerrild, Synthesia’s COO. This demonstrates a commitment to sharing the company’s success with the team that built it. Founded in 2017, Synthesia has grown to over 500 team members, operating from a 20,000-square-foot headquarters in London, with additional offices in Amsterdam, Copenhagen, Munich, New York City, and Zurich.
The Future of Employee Liquidity in the UK Private Market
While uncommon for British startups, this coordinated secondary sale isn’t unprecedented and is likely to become more prevalent. Synthesia’s head of corporate affairs and policy, Alexandru Voica, predicts that as UK-based private companies remain private for longer periods, structured employee liquidity options will become increasingly common. “My guess is that as [U.K.-based] private companies stay private longer, this type of structured, cross-border employee liquidity may become increasingly common, so I wouldn’t be surprised to see others do it, either with Nasdaq or others,” he told GearTech.

The company's next steps will be crucial in solidifying its position and capitalizing on the immense potential of the AI agent market.
