London-based startup Synthesia, specializing in AI-generated video content, has reached a major milestone — surpassing $100 million in annual recurring revenue (ARR). Founded in 2017, the company now employs over 550 people globally and continues to lead in the generative video space.
Synthesia enables companies and individuals to create realistic videos using digital avatars that mimic real human speech, expressions, and behavior — all from a simple text script, with no actors or filming required.
Its technology is widely used in corporate training, marketing, support, and content localization. Clients include Amazon, Heineken, Accenture, and Reuters.
Key facts:
— ARR exceeded $100M as of April 2025
— 550+ employees worldwide
— Supports over 50 languages and 120+ AI avatars
— Recently launched: Synthesia STUDIO 2.0
Synthesia’s growth confirms a global shift: generative video is moving beyond experimentation and becoming a core part of corporate workflows. The barrier to video production is rapidly falling, while the realism of avatars and speech synthesis now approaches cinematic quality. What once took weeks — training videos in multiple languages — now takes hours.
