Synthesia
British AI company that generates professional videos using synthetic avatars and cloned voices, used by most Fortune 100 firms.
Wikipedia – Synthesia (company)Synthesia Limited is a British multinational artificial intelligence company headquartered in London, UK, founded in 2017 by Victor Riparbelli, Steffen Tjerrild, Lourdes Agapito, and Matthias Niessner. It develops synthetic media-generation software that lets users create professional AI-generated videos—complete with AI presenters or personal cloned avatars—without cameras, actors, or editing software, with a free voice library spanning 140 languages and accents.
The platform is optimised for corporate use cases such as training, onboarding, and internal communications. It is used by 70% of FTSE 100 companies and over 90% of Fortune 100 companies, and by June 2025 its 65,000 customers had collectively created 150,000 personal AI avatars, making it Britain's largest generative-AI firm.
Synthesia achieved unicorn status at a $1 billion valuation in June 2023 after raising $90 million from Accel and Nvidia's NVentures, and reached a $4 billion valuation in January 2026. The company enforces responsible-AI policies that require explicit consent for any use of an individual's likeness and prohibit non-consensual cloning of celebrities or public figures.
An AI-powered video-generation platform at this scale—deeply embedded in Fortune 100 workflows—represents a direct and significant use case for any innovation touching synthetic media, avatar technology, enterprise communications, or responsible AI governance.
