Synthesia, an AI video platform for business, has raised £150 million in a Series E funding round led by Google Ventures, with participation from Evantic and Hedosophia. Other existing investors NVentures, Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital, and MMC Ventures also participated, reaffirming their commitment to Synthesia’s long-term vision. The funding values the company at $4 billion.
Synthesia plans to use the capital to build a category-defining company focused on transforming how employees learn and share knowledge across organisations, including enterprise learning and development, knowledge sharing, product marketing, and sales enablement.
Organisations are increasingly under pressure to keep employees informed and skilled amid rapid changes in products, regulations, and ways of working. Synthesia addresses this by enabling companies to communicate and train more effectively using video and interactive formats rather than static content.
The company is developing a new category of products focused on conversational agents designed for organisational learning and upskilling, allowing employees to engage with company knowledge through questions, role-play, and tailored explanations.
Founded in 2017 and headquartered in London, Synthesia is used by over 90% of the Fortune 100. With this funding, it will continue investing in agent-based products and improvements to its existing platform to support long-term, responsible growth.
