Synthesia raises $200m at $4bn valuation, say reports

The round comes 10 months on from the AI darling’s previous $180m Series D

AI video startup Synthesia has raised $200m and nearly doubled its valuation to $4bn, according to reports. 

The raise comes less than a year on from the AI darling’s previous raise, as investors scramble to throw money behind Europe’s most promising AI startups amid talk of an AI bubble emerging. 

Less than a year on from Synthesia’s previous $180m Series D at a $2.1bn valuation, Alphabet-backed investor GV has led the fresh round into the company, according to Forbes, citing three sources familiar with the matter.

It takes the startup’s total funding to over $500m.

Founded in 2017, Synthesia reported hitting $100m in annual recurring revenue (ARR) in April, a figure which has since risen above $150m, the Information reported last week.

The company, which is building video generation software that creates avatars of people for internal and external company communications, has become one of the UK’s tech darlings in recent years. 

Synthesia held talks with Software giant Adobe to be acquired for $3bn, which the Times reported the company rejected. Meta also discussed a possible M&A for the startup, the Information said.
