Synthesia has raised $200 million (£146 million) in fresh funding in a round led by Google Ventures, pushing the London-based company’s valuation to $4 billion and cementing its position as one of the UK’s most valuable artificial intelligence businesses.
The investment marks a sharp step up from Synthesia’s previous £146 million Series D round in January 2025, which valued the company at $2.1 billion, highlighting the speed at which the business has scaled amid the global AI boom.
The latest round also attracted backing from Evantic, founded by former Sequoia partner Matt Miller, and Hedosophia, alongside participation from existing investors including NVentures, Accel, Kleiner Perkins, New Enterprise Associates, PSP Growth, Air Street Capital and MMC Ventures.
As part of the transaction, Synthesia will also facilitate an employee secondary share sale in partnership with NASDAQ, priced at the new $4 billion valuation.
