During the holiday, safety is a concern. Whether it be protecting your home or yourself if shopping later at night, we found some startups helping you in this effort. Each week, TechCo features tech startups that can help streamline your daily life. This week in Startup Spotlight, we found smart jewelry for emergency situations, a solar stove, smart lights for grandma, and more. Staying safe while on-the-go, at night or on a date, is a constant running dialogue in a woman’s mind.
