Synthesia, the London AI company whose software lets businesses make training and corporate videos with digital presenters, nearly doubled its revenue to $113.2m (£85m) in 2025 while its losses widened, newly filed accounts show.
Revenue was up from $58.3m in 2024. The pre-tax loss grew to $69.9m as the company kept spending to grow: the directors said it “continued to invest heavily in key areas including product, sales and marketing”, and its workforce grew by more than a third.
Synthesia was founded in 2017 by a group of AI researchers and entrepreneurs, including chief executive Victor Riparbelli. It sells subscriptions mainly to large companies and says 90 per cent of the Fortune 100 and 70 per cent of the FTSE 100 are customers.
In January it announced it had raised $200m from investors led by Google Ventures, in a round that valued it at $4bn.
The US is its biggest market, and Synthesia says it now brings in about half its revenue. In September the company opened a New York office nearly four times the size of its previous one.
It is also building products that go beyond recorded video. Sessions, launched on 1 October, uses interactive avatars to coach, interview and guide users.
