“My thighs rub together. My boobs sweat. And my B.O. is the worst!” says Katie Sturino on her company’s website. “I couldn’t find products I loved to address issues like these, so I started Megababe!”

Megababe creates and sells “clean” body care products such as deodorant made of coconut and willow bark extract and a shaving stick made of sea moss and ginger root oil. Sturino founded the company in 2017 after working first in public relations then as an influencer, and Megababe products are now sold at major retailers including Target and Walmart.

In its eight years, Megababe has grown to a team of 11, says Sturino. When it comes to how she susses out whether someone is a good fit for the team, there’s one question she likes to ask above all: “What’s the most consistent piece of negative feedback you get?” she tells CNBC Make It.

Sturino wants “to see your mess,” she says, or a candidate’s weaknesses.
