My name is Christopher Czellary and at just 17 years old, I was on Germany's biggest startup show, Die Höhle der Löwen (Shark Tank). There, I was able to convince Ralf Dümmel and secure a deal.

On the show, I presented my product Peak Protect, an innovative phone security device with a retractable steel cable, which reliably protects smartphones from loss and theft.

Particularly exciting was the unique battle between two teen founders: I competed with Peak Protect against another startup and ultimately prevailed. My offer of 75,000 Euros for 25 percent convinced the investors and ultimately led to a deal with Ralf Dümmel.

Then known as Peak Protect, today Easy Protect.

Since the broadcast, a lot has happened. We are now widely represented in brick-and-mortar retail, including Netto Marken-Discount, Kaufland and Müller, as well as online on Amazon.

The product was a complete success and was quickly established on the market.

Currently, we plan to further expand our presence and place the product in sports stores and other retail chains in the future.
