Synthesia doubled its price tag to $4B after closing a $200M Series E led by Google Ventures, cementing its lead in enterprise AI video.
The London startup turns scripts into multilingual, avatar‑driven clips for training, onboarding, and sales—now used by blue‑chip clients worldwide.
Coming just nine months after a $2.1B round, the new capital signals accelerating demand and a clear path to global scale.

| Series A | 2021 | $12.5M | – |
| Series B | 2021 | $50M | – |
| Series C | 2023 | $90M | $1B |

How Synthesia Became Enterprise Video's Fastest-Growing Platform?
Synthesia automates video production for enterprises. Input a script, select an AI avatar, and the platform generates broadcast-quality videos in 140+ languages. No actors. No studios. No production delays.
The company serves 90% of Fortune 100 firms—think Zoom, Heineken, and Bosch—plus 60,000+ total customers. Most critically, Synthesia crossed a milestone in August 2025: $100 million in annual recurring revenue achieved in just 36 months from launch.
On a single day in October, the company generated $2 million in revenue. That velocity attracted GV's continued investment.
Why Google Ventures Is Doubling Down?
GV's participation signals confidence in three competitive advantages:
The Numbers Behind the Growth Story
| Metric | Value | Context |
|---|---|---|
| Series E Valuation | $4B | 90% increase from Series D |
| Annual Recurring Revenue | $100M+ | Achieved in 36 months |
| Daily Revenue Peak | $2M | Single day in October 2025 |
| Customer Base | 60,000+ | Growing 4x weekly active users |
| Fortune 100 Penetration | 90% | Market concentration play |
| Language Support | 140+ | Global enterprise reach |
| Total Capital Raised | $536M | Across all funding rounds |
What's Next: Interactive & Real-Time Video
Synthesia is shifting from static video generation toward video agents—interactive AI avatars that respond to queries in real-time. Use cases include sales training (practice pitches with an AI prospect), customer support (multilingual support avatars), and internal comms (questions answered by company spokesperson avatars).
The new capital funds product innovation, international expansion (especially North America and Japan), and talent acquisition. The company recently hired Peter Hill as CTO—a 25-year Amazon veteran who led technical divisions at scale.
The Rejected Adobe Acquisition
In early October, reports surfaced that Adobe offered $3 billion to acquire Synthesia. CEO Victor Riparbelli declined. At $4 billion valuation just weeks later, that rejection looks prescient—assuming the company can sustain growth momentum.
