Diabetes and depression sometimes go hand in hand, so when co-founder and CEO of Silicon Valley startup Omada Health noticed how many people on its diabetes treatment program were also battling depression and anxiety, he decided the company would take on the psychological issues of its customers, too.

At first, investors doubted that there would be a literal market for Thrive Market, a membership-based grocer (like Costco) that sells natural and organic food products at a discounted price online. But the company found its base with budget-minded moms, and its private label has recently taken off. The company serves an important need as the wellness industry attempts to democratize. But will Amazon's Whole Foods inevitably steamroll Thrive Market's early success?

Momentum, Done, HabitMinder, Habit List … these are only a few of the dozens of apps out there that aim to help users develop healthy habits, whether that's taking walk breaks at work, drinking more water, or meditating every day.
