Lully joins the YC W15 batch: 

Lully cofounder Andy Rink grew up with a twin sister who suffered from night terrors. Each night, like clockwork, she would experience a terrible nightmare, but instead of waking from it instantly like most kids, she had to suffer through it.

That’s why Rink and his cofounder Varun Boriah teamed up to create Lully. After studying sleep patterns at Stanford Biodesign together, the duo took their research to the drawing board and realized that a strong enough vibration, at an easily predictable interval, could actually soothe the child through the potential period of night terror and let everyone in the house sleep peacefully.

Lully is a smart device that goes under the mattress of the child experiencing night terrors. Producing a vibration about 10x stronger than the one in your smartphone, the Lully brings children out of that unhealthy sleep pattern into a lighter sleep, avoiding the whole night terror episode before it even begins.”
