The next wave of enterprise AI won’t just generate content; it will teach, coach, and engage, and Synthesia is building that future.

We first led Synthesia’s Series A back in 2021, and today we’re thrilled to announce that they have now raised a $200 million Series E at a $4 billion valuation, led by GV (Google Ventures), with participation from FirstMark, NVIDIA, Accel, Hedosophia, Evantic Capital, and other long-time partners.

Synthesia is best known for its AI-powered video platform, which enables companies to turn text into high-quality, human-like video presentations. But the company’s next chapter goes further: interactive AI agents that can engage in real-time, two-way conversations. Starting with sales training and expanding into recruiting, onboarding, and internal communications, these agents move enterprise learning from static content to active, conversational experiences.

This vision is resonating with the market. Synthesia now serves global enterprises including Microsoft, UBS, and Ford, and recently surpassed $100 million in annual recurring revenue, placing it among the fastest-growing enterprise AI companies in the world.

While many AI startups chase consumer media or general-purpose models, Synthesia has committed to the much larger and more durable opportunity in enterprise communication and workforce upskilling, where ROI, trust, and integration matter.

As CEO Victor Riparbelli puts it, companies are under unprecedented pressure to reskill their workforce, and AI agents are becoming capable enough to meet that moment. Synthesia is building the infrastructure to power this shift responsibly, at scale, and with real customer traction.

We’re proud to partner with Victor, Steffen, and the entire Synthesia team as they continue to build a category-defining company at the intersection of AI, video, and enterprise learning.
