Synthesia Review — The Enterprise AI Video Platform That Hit $100M ARR, Rejected Adobe's $3B Offer, and Now Trains 70% of the FTSE 100

Four researchers from Cambridge, UCL, TU Munich, and Stanford founded Synthesia in 2017 as a research project in neural video synthesis. By October 2025 it had crossed $100M ARR, raised $200M at a $4B valuation, achieved ISO 42001 as the world's first AI video company, and deployed its platform inside 90%+ of Fortune 100 companies. We review the enterprise governance features, the SCORM export that HeyGen doesn't offer, the L&D integrations, and what it means that Synthesia rejected a $3 billion acquisition.
