14 & 15. Justin Woolverton & Doug Bouton — Cofounders of Halo Top

Halo Top is the low-calorie ice cream that has disrupted the industry, creating a whole new market and dozens of new companies wanting a scoop of the action.

Essentially, it makes low-fat, low-sugar ice cream that's also so low in calories you can eat a whole tub and only consume 360 (compared to over 1,000 in a tub of regular ice cream). But the reason Halo Top has become so popular is it actually tastes good, too.

Justin Woolverton and Doug Bouton are the two former lawyers behind the brand's success. The duo founded the brand in 2012 and Halo Top is now available in 12 countries across the globe — and continues to expand. Consumers buy it as an every-day product, compared to, say, Ben & Jerry's or Häagen-Dazs, which most people only treat themselves to occasionally. Needless to say, Woolverton and Bouton eat ice cream every day.
