Gab Waller: Who The Celebs Call, Now She's Building Fashion's Next Big AI App

From Sourcing Fashion to Building Tech—Gab Waller’s Empire

In this episode of Hot Smart Rich, Maggie sits down with Gab Waller—the fashion sourcer-turned-tech founder—who built a global empire from a single Instagram DM. Known for finding the most coveted luxury pieces for celebrities like Rosie Huntington-Whiteley, Hailey Bieber, and Khloé Kardashian, Gab has pioneered fashion sourcing and is now reshaping the future of luxury shopping with her tech platform, Sourced By.

✨ Episode Highlights:

Gab’s journey from a small town in Australia to becoming one of the most sought-after fashion sourcers is nothing short of remarkable. Starting her career in the Australian government, she took a leap into fashion, driven by a passion for luxury items and an eye for hard-to-find pieces. What began as a personal mission quickly turned global as she tapped into the high-demand market for sold-out luxury fashion.

Her big break came through an Instagram DM when she sourced an iconic Old Celine coat for Rosie Huntington-Whiteley. That single moment changed her career trajectory, positioning her as the go-to for celebrity clients seeking rare fashion. With names like Hailey Bieber, Sofia Richie Grainge, and Chiara Ferragni on her roster, Gab became the fashion world’s best-kept secret.

As demand skyrocketed, Gab saw an opportunity to scale beyond 1:1 sourcing. Enter Sourced By—the ultimate platform shaping the future of luxury shopping. Using AI to connect shoppers to rare items worldwide, the platform is the backbone of the fashion sourcing industry—a proof of concept that’s creating an entirely new space in fashion tech.

Key Takeaways:

• Passion to Personal Brand: Gab shows how focusing on a niche—like fashion sourcing—can build a global personal brand.
• Scaling a Brand into a Business: She transformed her personal success into Sourced By, proving personal brands can evolve into scalable businesses.
• Spotting Market Gaps: Identifying the unmet demand for sold-out luxury pieces was key to her entrepreneurial success.
• Scaling Without Losing Authenticity: Even as she moves into tech, Gab maintains the personalized touch that made her stand out.
• Building in Public: Her transparency—sharing wins and challenges—offers a blueprint for founders growing personal brands into global empires.
