London-based AI video creation platform Synthesia has raised $200 million (£146m) in a new funding round led by Google Ventures (GV), pushing its valuation to $4 billion.
The investment makes the business one of the UK’s most valuable AI companies and follows a prior £146m Series D round in January 2025.
That round valued the company at $2.1bn and its latest deal highlights the rapid rise of the now-UK giant amid the AI boom.
The latest round also saw participation from Evantic, the venture fund founded by former Sequoia partner Matt Miller, and Hedosophia.
Other existing investors NVentures (NVIDIA’s venture capital arm), Accel, Kleiner Perkins, New Enterprise Associates (NEA), PSP Growth, Air Street Capital and MMC Ventures also participated.
As part of the transaction, the business will also facilitate an employee secondary sale in partnership with NASDAQ at a $4bn valuation.
