In 2012, Jane Och, a mom and investment manager consultant, was taking a container of guacamole out of her fridge when she realized something.
She told CNBC:
"I realized that if I don't touch this container of guacamole, it will never turn brown. The second I put a chip in it, there's space. So I thought if somehow we could eliminate that space, then we've maybe solved this age old problem."
