How do you recover from a disastrous TV pitch to build a global children’s brand that sells in over 100 countries? In this episode, we sit down with Rob Law, founder of Trunki, the iconic ride-on suitcase that started life as a student design project and became a multimillion-pound business.

Rob shares the wild ride behind Trunki: from being publicly rejected on Dragons’ Den to selling out overnight, navigating lawsuits, scaling manufacturing, and launching new products through crowdfunding. Whether you're working on your first prototype or your tenth product line, this episode is filled with honest insights, smart strategy, and lessons in resilience.

In This Episode, You’ll Learn:

• Why Trunki’s journey started with a student design competition
• What really happened on Dragons’ Den—and why it was a blessing in disguise

• Why IP is important—but brand matters more
• What went wrong (and right) with their follow-up product launch
