From Frustration to Innovation: How The Green Sling is Changing Running Gear Forever

In this inspiring episode of The Bold Inventor Show, hosts J.D. Houvener and Matt Kulseth sit down with entrepreneur Maddie DeJong, the inventive mind behind The Green Sling—a sustainable running belt designed to solve the age-old problem of “Where do I put my extra layers?”

What started as a personal pain point during marathon training turned into a unique blend of functionality, sustainability, and entrepreneurship. Maddie shares how she went from frustrated runner to product creator, conducting market research while completing her master’s in entrepreneurship, and ultimately launching her business from the ground up.

Listeners get a behind-the-scenes look at how she:

• Developed a Minimum Viable Product (MVP) that went viral on LinkedIn.
• Built a supply chain of upcycled leggings to keep spandex out of landfills.
• Partnered with a Houston-based cut-and-sew studio that provides employment for women in need.
• Navigated the provisional-to-non-provisional patent process while bootstrapping her business.

Maddie opens up about the realities of product tweaks, the challenges of scaling sustainably, and her aspirations to bring The Green Sling into big-box retail stores. She also shares candid insights about pricing strategy, influencer marketing, and how staying true to her values differentiates her from fast-fashion copycats.

From her marathon finish line to pitch competitions and intellectual property strategy, this conversation is a goldmine for inventors, small business owners, and sustainability advocates alike.
