A decade later, after a string of failed tech startups and hundreds of late-night experiments in his New York apartment, he created a high-protein, low-carb cereal that tasted like the Cocoa Puffs he remembered. That homemade experiment became Catalina Crunch, now a brand doing roughly $200 million in annual sales.

From Kitchen Experiments to a Product-Market Signal

Kaliannan had been eating the same keto-friendly foods—eggs, nuts, chicken breast—for years. Living in New York, surrounded by the city's food culture but unable to participate, he started baking as a creative outlet. He began by replacing wheat flour with protein powder and sugar with monk fruit, trying to recreate the cookies and cereals he missed. The breakthrough came when he made a chocolate cereal in his apartment, mixing pea protein, cocoa powder, monk fruit, and baking powder into a dough, rolling it thin, scoring it into squares, and baking it. The first batches were "hard as a rock" and "tasted like soil," but he iterated. The real signal came when he gave a bag to a friend in Central Park. The friend, who was not diabetic, Venmoed him $

Show Notes

Krishna Kaliannan wanted to start a tech company but failed at every attempt. 


On the side, he was teaching himself how to cook with high-protein, low-sugar ingredients. Not just out of interest, but out of necessity. As a teenager, Krishna had been diagnosed with diabetes and epilepsy, meaning he adopted a keto diet long before it was trendy. 


Krishna’s home experiments with pea powder and monk fruit eventually became Catalina Crunch, one of the country’s most popular high-protein, low-carb breakfast cereals and snacks. 


In this episode, Krishna shares how a life-changing health condition sparked an obsession with healthy baking— and a brand that reimagined snacking.
