“If you follow your own path and your own passion it will shine through and you will be successful.”
What does it really take to turn a personal brand into a thriving business? This week on The Entreprenista Podcast, Stephanie sits down with fitness entrepreneur Katie Austin to unpack the decade-long journey behind building the KA App—a bootstrapped digital fitness and nutrition platform with hundreds of workout classes, healthy recipes, habit tracking, and an engaged community.
Katie opens up about growing up with fitness icon Denise Austin, forging her own path in an industry where comparisons are inevitable, and why slow, steady growth has been one of her greatest competitive advantages. From balancing a career in sports broadcasting while building her business from scratch to leading a remote team, navigating social media as the face of her brand, and preparing for motherhood, Katie shares the honest realities of entrepreneurship behind the highlight reel.
