The London firm, one of the early poster-children of Shoreditch’s Silicon Roundabout, said it expects to double sales this year, from around £5m to £10m, according to accounts filed to Companies House.
Mind Candy was a star of London’s technology scene in the mid 2000s, developing its online Moshi Monsters game series to appeal to young web users.
The bedtime stories series has enjoyed significant growth, CEO Ian Chambers said, and has recently begun adding celebrity story tellers to the app.
These have included US actor Goldie Hawn and Brian Blessed, the British actor known for his booming voice. “We had a laugh thinking about Britain’s loudest man reading children’s stories,” Mr Chambers said.
Mr Blessed said the sleep technology had been “a joy to work on”.
