Explanation

The word startup refers to either the process of beginning something or a new entrepreneurial business. The startup costs for your sister's startup might be higher than she thinks. Most startups offer their customers something innovative — a new product, like a dog toy that's truly indestructible, or an ingenious service, like a smartphone app that tells you where the closest public restrooms are.
