For Brian Smith and Jackie Cuscuna, co-founders of Ample Hills Creamery, building an ice cream business has been a rocky road.

The husband-and-wife duo started with an ice cream push cart before opening their first Ample Hills shop in Brooklyn, New York, in 2011. At its height, Ample Hills was valued at $40 million, with 13 scoop shops and an online store that shipped ice cream nationwide.
