How Synthesia's £180m Funding Boosts The AI Video Revolution

The enterprise video communications market has transformed since 2023, as AI removes traditional barriers of cost and complexity in corporate video production.
This shift arrives as multinational companies seek solutions for consistent, multilingual communication across global workforces, particularly for training, internal communications and customer engagement.
The demand for AI-powered video creation has intensified amid workplace changes that require organisations to deliver more frequent, personalised video content to employees and customers across different regions.
Now, traditional video production, with its requirements for studios, presenters and post-production teams, has proven too slow and expensive to meet this need.
Against this backdrop, Synthesia, which develops AI - powered video creation software for enterprises, has secured £180m (US$226m) in Series D funding led by NEA, valuing the London-based company at £2.1bn (US$2.58bn).
The investment establishes Synthesia as Britain's most valuable Gen AI media company by valuation, according to technology market intelligence firm Dealroom.
The funding round includes participation from existing investors GV, MMC Ventures and FirstMark, alongside new backers WiL (World Innovation Lab), Atlassian Ventures and PSP Growth and the investment brings Synthesia's total capital raised to £330m (US$413m).
Enterprise adoption drives Synthesia platform growth
The company's video platform, which enables organisations to create AI-generated videos for corporate communications, has attracted 60% of Fortune 100 companies as customers.
Synthesia's technology allows businesses to produce multilingual video content without traditional filming requirements.
"This new investment will help us develop a new generation of AI-powered video experiences that are interactive, real-time and personalised," says Victor Riparbelli, CEO and co-founder of Synthesia.
"I'm excited to bring these experiences to our over 60,000 customers."
The company also generates more than half of its revenue from the US, with operations spanning seven countries.
This global expansion happens as AI accounts for 25% of European venture capital investment, up from 15% four years ago, according to Dealroom founder and CEO Yoram Wijngaarde.
Synthesia technology platform development
In June 2024, Synthesia announced development of its enterprise AI video platform, Synthesia 2.0.
This platform includes features such as Personal Avatars, which create custom AI presenters speaking 30 languages and AI Screen Recorder, a Chrome extension for professional video creation.
The technology additionally includes a video localisation solution with one-click translation and AI-enhanced dubbing that synchronises lip movements with natural-sounding voices whilst a multilingual video player supports multiple translations of single videos with chapters and captions.
Global enterprise customers report implementation success
Global organisations report measurable improvements in communication efficiency using Synthesia's platform.
SAP
"Our partnership with Synthesia has been instrumental in driving an engaging way to interact with both our internal and external customers," says Lauren Maroney, Global VP of Strategic Engagement and Adoption at SAP.
“We have been active users of their platform and our use cases are continuing to expand at a rapid pace, thanks in part to the developments in place by the Synthesia team.”
Siemens
Additionally, Siemens uses the platform for global communications, Sven Windsch, Head of Technology Adoption at Siemens says: “Synthesia’s advanced platform, featuring speech-to-video transformation, multilingual support, digital avatar creation, and seamless brand integration, has optimised our content creation processes.
"These capabilities have enhanced our efficiency while elevating our ability to deliver high-quality, localised content with speed and precision."
IKEA
"In recent years, virtual facilitators have significantly replaced traditional human trainers, addressing key challenges such as the high cost, time intensity and single-language limitations of live actor recordings,” says Markus Lüken, Learning Technology Implementation Leader at Inter IKEA.
“Now with Synthesia, we have democratised learning for our global workforce by transitioning from subtitled English-only master videos to culturally relevant, locally adapted content.”
Leadership expansion and market position
The company has also appointed Peter Hill as Chief Technology Officer, bringing experience from his previous roles as CEO and CPO at Wildfire Studios and a 25-year tenure at Amazon and AWS.
The appointment comes as Synthesia expands its workforce to 400 people across offices in London, New York, Copenhagen, Amsterdam, Zurich and Munich.
Science, Innovation and Technology Secretary Peter Kyle highlights the investment's significance for Britain's technology sector: "Synthesia's latest investment is a powerful demonstration of how our Plan for Change is encouraging innovation and driving growth in the UK's thriving AI sector.”
Synthesia sets industry security standards
The company also achieved ISO 42001 compliance certification from A-LIGN in September 2024, establishing security benchmarks for the Gen AI industry.
Synthesia conducted public security testing with Humane Intelligence, a technology non-profit, in collaboration with NIST, the US government standards agency.
“NEA has a long history of supporting transformative companies and we're excited to partner with Synthesia as they shape the future of AI-powered communication," says Philip Chopin, Managing Director at NEA UK.
"We believe Synthesia's commitment to enterprise-grade solutions and its impressive traction with customers sets the company apart in a rapidly evolving market."
