JN Windows, LLC (Jamberry Nails)
A multilevel marketer of nail wraps and other beauty products who employed over 50,0000 nonemployee sales consultants, the company filed Chapter 7 bankruptcy in December 2018.
Formed less than a decade ago, it became an international beauty brand with consultants in U.S, Canada, Australia, and New Zealand and owed its success to its savvy use of social media like Facebook and Instagram.
