Key Takeaways
- Synthesia's valuation doubled to $4 billion after Series E funding led by GV.
- Employees can sell shares via Nasdaq-facilitated secondary sale.
- The company plans to invest in AI agents for interactive training.
Synthesia doubled its valuation to $4 billion with a $200 million Series E round, betting big on AI agents for enterprise training.
The London-based AI video platform announced the funding on Jan. 26, 2026. GV (Google Ventures) led the round with participation from Nvidia's NVentures and existing backers.
As part of the funding, according to company officials, Synthesia partnered with Nasdaq to facilitate a secondary sale allowing employees to cash out shares. Nasdaq is acting as a private markets facilitator — the company is not going public.
The British firm reportedly counts 70% of FTSE 100 companies as clients and crossed $100 million in annual recurring revenue last April. It plans to deploy the capital toward developing AI agents, interactive avatars that can answer employee questions during training sessions.
Inside Synthesia's Product Roadmap
Synthesia said it will use the funding to develop interactive training tools, including AI agents designed to engage users dynamically.
| Feature | What It Enables |
|---|---|
| AI agents | Interactive avatars that answer employee questions during training |
| Role-play scenarios | Employees explore situations through guided simulations |
| Personalized explanations | Tailored responses replace passive slide consumption |
A Rapid Climb to $4B
“Synthesia was founded on two core beliefs: first, that AI will bring the cost of content creation down to zero. And secondly, that AI video provides a better, more engaging way for organizations to communicate and learn. This funding round is about scaling that vision."

The company nearly doubled its valuation while rejecting a $3 billion acquisition offer from Adobe.
Throughout 2025, Synthesia built significant momentum. The year began with a $180 million Series D at a $2.1 billion valuation and the addition of Peter Hill as CTO after 25 years at Amazon.
By April, the company crossed $100 million in annual recurring revenue and secured a strategic investment from Adobe Ventures. In July, Synthesia opened a 20,000 square foot London headquarters.
The company also launched Synthesia 3.0 in October 2025, introducing interactive AI agents, multilingual dubbing and enterprise learning tools.
AI Adoption Hits a Turning Point
Enterprise AI adoption crossed a maturity threshold in 2025, moving from pilots to production-grade deployments.
Current adoption metrics show momentum:
- 88% of organizations regularly use AI in at least one business function, up from 78% a year earlier
- 18% of firms reached "AI future ready" status on the MIT CISR AI maturity curve, compared to 7% in 2022
- 65% of organizations now regularly use generative AI
- 66% deploy AI across multiple functions, with half using it in three or more areas
Despite widespread experimentation, confidence is running ahead of capability. Nearly two-thirds of organizations have not yet started scaling AI across the enterprise.
Organizations are allocating substantial budgets to AI initiatives, with AI budgets increasing by more than 10% as pilots transition to production. However, MIT research found that despite enterprises spending close to $40 billion on generative AI over two years, only 5% could point to real business returns.
