I know the founding team (3 out of 4 are Italians like me, all living in SF), and as a disclaimer, I am an early angel investor in the company.<p>I have tried the product in its alpha version, and have followed the progress thus far. I think that what Luna is trying to achieve is extremely important. In fact, I have decided to invest because I thought that improving someone's sleep is going to have a huge impact in his/her life.<p>I am not aware of any other product that is qualitatively similar to this. If there are, let me know :)<p>Good luck, guys!
