NightBalance, a spin-out of Delft University of Technology developing a treatment for obstructive sleep apnoea (OSA), has signed the support of the Netherlands’ largest healthcare payor Achmea for its sleep position trainer (SPT) as the company begins plans for a series B round.

The company previously received backing for an unspecified sum from Thuja Capital and Health Innovation Fund in 2011, which was followed by the commercial launch of its SPT in 2012. The SPT currently sells in 11 European countries, and further funding will be used to support an increased international reach.

NightBalance, founded in 2009, is adding to treatments for OSA. A condition which can effect sleep quality and can lead to hypertension, cardiovascular disease, stroke, and others, OSA is currently treated with continuous positive airways pressure or mandibular advancement devices, both of which are effective yet can be invasive and uncomfortable to use. The SPA encourages patients to not sleep in a supine position, thus reducing the effect of the condition.
