Headquartered in London, United Kingdom, Synthesia has been at the forefront of AI-driven video technology.

Its journey has been marked by significant milestones, including a remarkable achievement in funding, having raised over $156.6 million to date. In a Series C funding round led by Accel, with a strategic investment from Nvidia and participation from renowned investors such as Kleiner Perkins, GV, Firstmark Capital, and MMC, Synthesia garnered an impressive $90 million. This substantial funding valued the startup at $1 billion post-money, marking a remarkable growth from its $300 million valuation in December 2021.
