Synthesia

Synthesia is a London-based technology company that develops an AI video generation platform. Founded in 2017 by Victor Riparbelli, Steffen Tjerrild, Matthias Niessner, and Lourdes Agapito, its software lets users create videos featuring synthetic AI avatars and voiceovers from text scripts, without cameras, microphones, or studios. Users select from a library of stock avatars or create a custom avatar, type or paste a script, and the platform generates a narrated video in a range of languages. The product is used primarily by businesses for corporate training, learning and development, marketing, internal communications, and customer support content. Synthesia also offers features such as AI-assisted script generation, screen recording, and templates. It serves enterprise customers across many industries and reports adoption among a large share of Fortune 100 companies. The company has raised funding from investors including Accel, NVIDIA's NVentures, and Alphabet's GV, reaching a valuation of about $4 billion in 2026.
