Synthesia raises Series E: 90% of Fortune 100 deployed, SaaS margins, and Nvidia as investor
Jan 26, 2026 with Victor Riparbelli
Key Points
- Synthesia closes $180 million Series E with Nvidia as investor, reaching 90% Fortune 100 deployment through multi-year enterprise contracts rather than ad-hoc usage.
- The company derives 50% of revenue from internal use cases and 50% from external deployments focused on high-explanation content like product explainers and enablement materials, not marketing.
- Synthesia is building interactive video experiences where users role-play against AI agents post-training, positioning agentic video as its next major revenue driver.
Summary
Synthesia has closed a Series E round at $180 million, with Victor Riparbelli citing revenue quality rather than growth rate as the defining narrative for investors. The company counts 90% of the Fortune 100 as deployed customers, with contracts structured as multi-user enterprise agreements rather than exploratory credit-card signups.
The business splits roughly 50/50 between internal and external use cases, though Riparbelli pushes back on the assumption that external means marketing. Synthesia's external deployments lean heavily toward what he frames as "PowerPoint-style" content — product explainers, enablement materials, competitive battle cards — rather than performance advertising or brand storytelling.
The clearest product-market fit sits in complex, high-explanation categories including insurance, pharmaceuticals, and enterprise software. Riparbelli's thesis is that video outperforms text documents at conveying dense information, and that large software companies with tens of thousands of landing pages represent a largely untapped conversion opportunity.
The next product direction is the intersection of video and agentic AI. Synthesia is building interactive video experiences where, after watching training content, users enter a role-play simulation with an AI agent — for example, practising sales objection handling against a simulated customer. Riparbelli positions this as the company's next significant revenue opportunity. Nvidia is among the investors in the round, a signal of strategic alignment on the underlying AI infrastructure side of the business.
