Does Your Business Idea Pass the Eyebrow Test?

Next time you want to know what someone really thinks of your business idea, check out their eyebrows.

Ian Siegel, CEO and co-founder of job search platform ZipRecruiter, says people will naturally raise their eyebrows if they like what you’re pitching. If they lower their brows, that’s a bad sign.

“No matter what the words are coming out of their mouth, they’re not with you,” Siegel says.

Siegel and his business partners began building ZipRecruiter in 2010 while working full-time jobs. Based in Santa Monica, Calif., the company claims to have helped more than 1 million businesses post jobs.
