Synthesia

Synthesia, founded in 2017, builds an AI video platform for business that turns text scripts into professional videos without microphones, cameras, actors, or studios. Organisations use it to train, onboard and upskill employees. The founding team comes from research and entrepreneurial backgrounds at Stanford, Cambridge, UCL and TUM.

The company's technical work spans generative AI, AI video synthesis, text-to-video, AI avatars, AI voice synthesis and machine learning. Its platform generates videos from a selected presenter and a typed script; supporting components include a library of more than 240 AI avatars and over 1,000 AI voices covering more than 160 languages. A standing commitment to AI safety and ethics is reflected in the practice of dedicating 10% of the team to that work at all times.

The platform is trusted by over 90% of the Fortune 100 and used by more than 50,000 teams worldwide, with customers including Amazon, Zoom and Microsoft. It holds a G2 rating of 4.7/5 based on more than 2,000 five-star reviews. Funding exceeds $530M in total, including a $200M Series E, at a $4B valuation. Primary use cases sit in corporate training and learning and development, employee onboarding and upskilling, and enterprise business communications.
