Synthesia reached a $4 billion valuation in January 2026. This expansion followed a $200 million Series E funding round in October 2025 involving GV, Nvidia, and Accel. This preceded a $180 million Series D in January 2025 that doubled the valuation to $2.1 billion. The company also serves 90% of the Fortune 100 and earns over $100 million annually. Lourdes Agapito, Matthias Niessner, Victor Riparbelli, and Steffen Tjerrild co-founded the company in 2017. Peter Hill joined as CTO in January 2025 after serving as CEO and CPO of Wildfire Studios.
The company faces scrutiny over the potential for misuse of its synthetic media. A Freedom House report from October 2023 stated that governments in Venezuela, China, Burkina Faso, and Russia used Synthesia tools to create fake TV news outlets with AI-generated avatars for propaganda. Synthesia implements a strict pre-screening regimen to prevent deepfaking and prohibits the creation of non-consensual clones. The company is SOC 2 Type II and ISO 42001 certified and maintains GDPR compliance.
Syren drives the production process
Syren, the AI video agent, writes the script, designs the scenes, and adds voiceover and music while the user watches the video build live, scene by scene, in the interface. You already know that enterprise video needs scale. Users provide a prompt, document, or link to start the process. The system then generates a draft with a script, scenes, and an avatar presenter. Synthesia users can select to use specific models such as Veo 3.1, Gemini Omni, or FLUX 3 within the AI Playground to generate cinematic video clips from text or image inputs for their various professional video projects.

The platform manages the entire creation workflow from initial idea to finished video. Users refine the content by asking for a shorter intro, a new voice, or a different visual style in chat. The software applies brand colors to every draft and allows users to restyle any scene without touching a timeline. Users can design avatars with Avatar Builder or use pre-generated presenters. On Starter plans and above, users create personal avatars from a photo and a short consent recording.
The platform supports the creation of videos from PowerPoint, documents, or URLs. Users edit motion graphics text, numbers, and colors directly. The company reached 65,000 customers by January 2025. The software provides full transcripts for every interaction and shows viewers and drop-off points via Analytics. Users can add quizzes, clickable CTAs, and branching paths so viewers do more than watch.
Enterprise scale and interaction
Teams use Synthesia to create training videos, onboard new hires, enable sales teams, and share internal updates. The software supports 140+ languages and includes AI dubbing to translate finished videos with natural-sounding voices. The platform also includes interactive avatars that can conduct roleplay sessions or survey sessions. In roleplay sessions, an avatar responds and pushes back to help users practice hard conversations like cold calls or tough feedback.
In survey sessions, an avatar asks questions and follows up on what people say to provide themes and sentiment across every response. The company reached 65,000 customers by January 2025. The software provides full transcripts for every interaction. Users can manage content across teams in shared workspaces and keep every video on brand with Brand Kits. The Synthesia API allows for programmatic video generation or the addition of real-time interactive avatars to a website or support flow. The company launched Synthesia 3.0 in October 2025, which includes hyper-realistic digital avatars. How will the company respond to the increasing sophistication of independent video models?
