Colorado’s Marquez and Ondrea Fernandez appeared on Season 9 of “Shark Tank” to seek investment for their company, The Dough Bar — doughnuts that are protein-filled, macro-friendly snacks. Here's what became of the company after Barbara Corcoran accepted Marquez and Ondrea’s offer for $300,000 and a 20% stake.

Initially, the company had been selling protein-infused doughnuts through its website but opened a brick-and-mortar location after online sales surpassed $2 million. However, because of a few financial blunders, The Dough bar filed for Chapter 11 bankruptcy in 2019, shortly after Barbara Corcoran backed the brand.

Despite the hardships, the struggles of the co-founders have made The Dough Bar into a multimillion-dollar business. The official website features the co-founders’ wisdom: “Don't be afraid to try again; sometimes the second time's the charm,” which can be interpreted as their current success after hitting a few rough patches.
