Synthesia

Synthesia (operating at synthesia.io) is a synthetic media-generation platform engineered for businesses to create professional videos without cameras, microphones, actors, or studios. Founded in 2017 by a team of researchers and entrepreneurs from UCL, Stanford, TUM, and Cambridge and headquartered in London, United Kingdom, Synthesia transforms text scripts into presenter-led videos using AI avatars. Under the hood, the platform leverages advanced AI to generate lifelike audio-visual agents and cloned avatars, enabling users to produce high-quality video content at scale. This allows corporate clients—including over 90% of the Fortune 100, such as Amazon, Zoom, and Microsoft—to streamline training, onboarding, and internal communications. Backed by over $537 million in funding across multiple rounds, including a $200 million Series E at a $4 billion valuation, Synthesia is positioned as a category leader in AI-driven video production for enterprise applications.
