Madalina Defta is the CEO and co-founder of Kaizen, one of the fastest-growing food brands in the high-protein, low-carb space. Originally from Romania, she immigrated to the U.S. at 24 with just $300 and built a successful corporate career in finance, strategy, and operations, holding leadership roles at GE, eBay, and Twilio. She has since scaled Kaizen into a thriving, profitable, and fully bootstrapped company—not through outside investment, but by focusing on quality, innovation, and a loyal customer community. Under her leadership, Kaizen has grown into a category leader, proving that a customer-first approach is the key to sustainable success.
