Founder of a new startup- myLifeGuard is a 24/7 Personal Lifeguard System for people living alone or often alone and at risk of not getting help for too long of time when they need it. Like a lifeguard, it provides help quickly if you ask for it, but it also constantly makes sure you are OK in the background, and checks if it can't tell. As a loved one or friend, if you don't hear anything it means the person being guarded is OK, and you can see their OK status any time you want just looking at your phone home screen.
