Our take
Video is an integral part of companies’ marketing strategies, and the adoption of synthetic media has grown in popularity. As organisations are investing in videos, startups are building platforms to support the process. Synthesia is an AI-powered video generation platform that saves enterprises up to 100x the cost and time of producing a video.
The company leverages deep learning to simulate real videos and real actors without the need for costly infrastructure like camera crews, actors, cameras, studios, and a lengthy post-production process. Synthesia’s first product STUDIO launched in public beta in the summer of 2020 and it is now used by 30,000+ companies, including the BBC, Teleperformance, Amazon, and Reuters.
Notably, Prof. Matthias Niessner, one of the co-founders of the company, is behind some of the most well-recognised research projects in the field Deep Video Portraits and Face2Face. The company's intuitive interface has grown to become the #1 rated video creation platform, proving its strong ability to capitalise on the growing AI in media market – which is estimated to be worth $99.48 Billion by 2030.
