A manufacturer of sleep aid technologies is targeting growth after a seed investment round.

Sheffield-based Braintrain 20:20 raised £485,000 from Mercia Fund Management and angel investors which included sleep specialists and healthcare entrepreneurs.

Braintrain 20:20 will use some of the money to complete a clinical trial at a sleep research centre.

Its first patented product SleepCogni builds a sleep programme for patients based on heart rate, skin temperature and oxygen levels in the blood.

It uses a bedside device and speaker system to deliver cognitive behaviour therapy via light and sound.

Its initial prototype was built at Sheffield Hallam University. Fifty per cent of its users experienced an improvement in their sleep compared to other groups using traditional relaxation music.
