British startup Synthesia has achieved a remarkable $4 billion valuation following a successful $200 million Series E funding round, a significant increase from its previous valuation of $2.1 billion just a year prior. This growth underscores the potential of its AI-driven platform, which revolutionizes corporate training through interactive videos featuring AI-generated avatars.
Unlike many AI firms still striving for profitability, Synthesia has carved out a strong niche in the training sector, boasting enterprise clients like Bosch, Merck, and SAP. The company crossed an impressive $100 million in annual recurring revenue (ARR) as of April 2025.
The Series E funding, which nearly doubled the company’s market value, was spearheaded by GV (Google Ventures) and included participation from other previously involved investors such as Kleiner Perkins, Accel, New Enterprise Associates (NEA), NVIDIA’s NVentures, Air Street Capital, and PSP Growth.
Although Synthesia is not going public at this time, Nasdaq is facilitating a liquidity opportunity for early team members to convert their shares into cash. This secondary sale, tied to the company’s latest valuation, will allow employees to benefit from their stake in the business while maintaining some level of control over the process.
Looking ahead, Synthesia aims to expand beyond its current offerings by incorporating AI agents that enable users to engage more interactively with company knowledge. This development will allow employees to ask questions, role-play scenarios, and receive tailored guidance, enhancing both engagement and knowledge transfer. Initial feedback from pilot programs has been positive, prompting the company to emphasize AI agents as a strategic priority alongside ongoing platform enhancements.
While Synthesia has not disclosed specific revenue projections, the company anticipates that its innovative solutions will address the pressing challenge enterprises face in effectively training their workforces amid rapid technological change. Co-founder and CEO Victor Riparbelli noted a significant convergence of technological advancement and a heightened focus on upskilling, suggesting a transformative era for corporate training priorities.
Founded in 2017, Synthesia has grown to employ over 500 individuals, with a headquarters in London and additional offices in cities including Amsterdam, Copenhagen, Munich, New York, and Zurich.
