Founder at Killer Koozys

“At the end of my internship, the CEO asked me if I would like to stay and work for them full-time.”

What are you up to in your current career or studies?

I’ve been a koozy collector since I was a kid, and when I moved to Barcelona, I realized they were nearly impossible to find. That’s what inspired me to launch Killer Koozys - bringing these fun, practical drink accessories to Europe. Koozys are neoprene sleeves designed to keep drinks cold or hot up to 50% longer, making them perfect for the beach, BBQs, hiking, skiing, and park picnics.

Killer Koozys was officially founded on February 22, 2024, and we specialize in white-label koozys for brands looking to boost their visibility and customer engagement. Our products are great for events, trade shows, employee welcome packs, new student kits, and more.

We recently signed an exciting contract with FC Barcelona to produce their official koozys!

How did your career path evolve after your Connect-123 internship? Did it influence your direction?

Connect-123 100% influenced my direction. During my internship, my dad told me, "if you ever want to live and work abroad someday, now this is a great opportunity to prove yourself in the internship, because they might hire you full-time. You never know." So because I was having so much fun in Spain and thought this would be a pretty sweet place to live, I decided to work my butt off, and sure enough, at the end of my internship, the CEO asked me if I would like to stay and work for them full-time. That's how I've ended up living in Spain for 7 years and starting my own company, Killer Koozys.

What made you choose to host an intern yourself, and what was the process like being on the other end with Connect-123?

As an ex-Connect-123 intern myself and now an employer who has worked with 3 interns through their program, I can without a doubt say, the quality and professionalism that goes into matchmaking is unparalleled. Each time we work with a Connect-123 intern, we can rest assured that the student is smart, driven, and eager to help our company grow.
