According to Tech Crunch, French startup Rythm has announced that it is has raised more than $11 million for its headset designed to improve sleep.

French startup Rythm, which makes a tech-infused headset it claims improves sleep quality, announced Tuesday that it’s raised over $11 million from private investors and public grants. The ‘Dreem’ headset was announced last month, but only in a prototype form — this money should help bring it to a planned full consumer release in early 2017.
