Synthesia, the London-based artificial intelligence video company, has raised $200 million in a Series E funding round that values the business at $4 billion, underlining sustained investor appetite for enterprise AI tools despite a more cautious global venture market.
The latest financing was led by existing backer Google Ventures (GV), with participation from Evantic, the venture fund founded by former Sequoia partner Matt Miller, and Hedosophia. A number of Synthesia’s current investors also joined the round, including NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital and MMC Ventures.
The fresh capital will be used to accelerate product development and support Synthesia’s ambitions to build what it describes as a category-defining company in AI-driven workplace learning and communications. The company said it aims to transform how employees learn and share knowledge across organisations, spanning enterprise learning and development, knowledge sharing, product marketing and sales enablement.
Synthesia’s platform enables businesses to generate video content using AI, positioning the product as a faster and more scalable alternative to traditional filming and editing workflows. The company is targeting corporate use cases where organisations need to create training, internal communications and customer-facing content at speed and across multiple markets.
In addition to primary fundraising, Synthesia said it will facilitate an employee secondary sale in partnership with NASDAQ. The move is intended to provide liquidity to long-serving team members while allowing them to remain shareholders, a structure increasingly common among later-stage technology firms seeking to retain staff as valuations rise and holding periods lengthen.
The funding announcement also drew support from senior figures in UK government, as ministers look to position Britain as a leading destination for AI investment and innovation. The UK’s Chancellor of the Exchequer, Rachel Reeves, said: “Synthesia is a UK success story, creating new jobs and opportunities in this country. It shows that by backing innovators to start, scale and stay in the UK through better access to finance and generous tax reliefs, we can turn the promise of AI into better-paid jobs and long-term growth across the UK.”
Synthesia was founded in 2017 and is headquartered in London, with offices across Europe and the United States. The company markets itself as an AI video platform for business and claims it is used by over 90% of the Fortune 100, 70% of the FTSE 100, and 90% of the CAC 40 and DAX 40, highlighting a customer base concentrated among large enterprises.
The company said it is developing products designed to enhance visual communication and enterprise skill development, reflecting a broader trend of businesses adopting AI tools to improve productivity and standardise training. With organisations under pressure to upskill staff and share information more efficiently, corporate learning and development has become a key battleground for AI adoption.
For investors, the funding round signals continued confidence in Synthesia’s ability to scale within the enterprise software market, where customers typically demand strong governance, security and reliability. The participation of existing backers alongside new capital suggests the company has maintained momentum as competition intensifies in generative AI tools for business.
Synthesia said the funding will also support further development of “agentic systems”, as it looks to expand beyond video creation into more automated workflows that can help businesses produce, personalise and distribute content at scale. The company believes such systems can play a growing role in how organisations train staff, communicate internally and enable sales teams with up-to-date materials.
With a $4 billion valuation, Synthesia is among the more highly valued UK-based AI firms, adding to a growing cohort of London-headquartered companies attracting significant late-stage funding. The latest round also comes as the government seeks to strengthen the UK’s reputation as a place where technology companies can start, scale and remain headquartered, rather than relocating as they expand internationally.
