The hardest part about responding to everyone’s testing questions is… so many don’t apply. Not only do many zipper consumers not understand the testing requirements of current zippers, but they’re all stuck in a mindset of nitpicking between the exact same things.

Switching Costs
I pitched an investor a week or so ago and she asked me about switching costs. I said, “I don’t think any company has switching costs.” She didn’t agree. Now, I realize that I was speaking from my perspective. All of the companies that contact me whether in fashion,Read More…

Little But Mighty
The power of standardization is that ZS closures are ALWAYS air-tight, water-tight, and gas-tight no matter their size. The shape is constant. The only difference is the dimensions of the shape. The ZS closure can be smaller, larger, or the same size as an old-fashioned closure…such as aRead More…

Stronger Closure for Flexible Packaging
Zipr Shift has invented a new packaging zipper track that is much more durable than the current packaging zipper track. It will allow for much heavier items to be placed in resealable packages. The strength comes from the internal metal clips that provide rigidity and from the flanges that grip andRead More…
Research & Development: Iteration, Innovation, Disruption
Recently, I was interviewed by Jeff St. Clair of WKSU NPR about what led me to disrupt zippers: Young Cleveland Entrepreneur Looks to Undo the Zipper Industry. It all started with my rabbit eating the zipper on my laptop case. I seek to disrupt zippers where others have merelyRead More…
