Synthesia

Product overview

Synthesia is a London-based company that lets users create videos with AI-generated avatars from text scripts. Users type a script, choose an avatar from a library of over 240 options or create a digital twin of themselves, and the platform produces a video where the avatar speaks the text with synchronized lip movements and gestures. The output is available in over 160 languages and can be translated with one click. The company was founded in 2017 by a team including researchers from University College London. It has raised over $536 million in total funding, with a $200 million Series E led by GV (Google Ventures) in October 2025 that valued the company at $4 billion. Earlier investors include Accel, Nvidia's NVentures, and Kleiner Perkins. Synthesia reportedly rejected a $3 billion acquisition offer from Adobe. The team numbers over 400 people, with headquarters at Regent's Place in London. More than 60,000 companies use Synthesia, including 90% of the Fortune 100. Clients include Zoom, SAP, Heineken, Reuters, and Teleperformance. The platform is used mainly for corporate training, onboarding, product demos, and internal communications. In late 2025, the company launched version 3.0 with Video Agents, interactive avatars that can hold real-time conversations with viewers.
