In this candid episode of Tenacity with Sonia C., host Sonia Couto sits down with Gary LeBlanc, founder and CEO of 0dB, for an honest conversation about entrepreneurship, resilience, and the true cost of building something meaningful.

Gary shares his journey from a successful corporate career to founding a neuroscience-backed functional beverage brand, sparked by personal loss, a deep commitment to wellness, and a desire to build with integrity. What unfolds is not a glossy startup story, but a candid look at burnout, pivots, sunk costs, and the emotional toll of staying in the game when the odds aren’t in your favour.

Together, Sonia and Gary unpack what it’s really like to:

• Build a product rooted in science and integrity in a crowded wellness market
• Navigate brutal supply chain and regulatory challenges as a Canadian founder
• Question whether to keep going, or let go, after years of sacrifice
• Balance ambition, mental health, and family as an entrepreneur
• Recognize when passion turns into resentment, and what to do next

This episode is compelling for founders who are quietly asking themselves:

“How much gas do I have left in the tank?”

Sonia guides the conversation with empathy and clarity, creating space for founders to feel seen while extracting hard-earned lessons you won’t find in pitch decks or MBA textbooks.

If you’re building through uncertainty, facing a pivot, or redefining what success looks like in your next chapter, this conversation will stay with you.
