Shea Kim is a Greenville, South Carolina woman who has an entire business dedicated to self-defense. She’s the owner of Definite Defense, a company that specializes in firearm training, including women’s-only gun classes.

Kim says most types of preparedness offers a level of comfort and confidence that acts as its own security. However, she says there are many women who are not comfortable carrying a weapon, so she’s working to create another option.

“People have apps on their phones for everything now, I figured maybe they could have an app they could hit it if they were in distress,” Kim said.
