J1B: Built by Youth, Backed by Vision

It all started at the kitchen table — two high school siblings, a conversation, and a sketch. With a little guidance from our dad, we reimagined the bottle: no plastic leaching, no flavor cross-contamination — just a cleaner, better experience.

Fueled by that idea, we launched a Kickstarter campaign. In just two hours, over 500 backers fully funded our dream, turning our concept into reality. But J1B became more than just a bottle — it became a platform.

That summer, a team of high school and college students came together to build more than a product. They built a brand. From video to website, branding to messaging, it was youth-led from the start. At J1B, we believe the best ideas emerge when young people are trusted to lead.


Our mission is simple: empower the next generation to turn creativity, skills,and passion into products that solve real-world problems. Because when youth are given the tools — and the trust — they can change everything.

Let’s Make This Simple.

THE PROBLEM WITH PLASTIC
People who regularly drink from plastic bottles consume around a credit card's worth of plastic… every week. That’s more than eating your Airpods, case and all, every single year. Not to mention the environmental implications of plastic bottle use. Like most people, we at JustOneBotl don’t subscribe to this lifestyle. We prefer insulated glass, so that’s what we made.

THE PROBLEM WITH METAL
Metal is porous, which means it retains bacteria more stubbornly than plastic or glass. That’s why you can never fully get rid of those lingering tastes from drinks other than water. You also can’t see what you’re drinking. We think you deserve to pour more than just water in your bottle and hope you do too.

THE PROBLEM WITH GLASS
There is a reason fine wines are served in glass. Glass containers are the purest way to drink any liquid. But glass breaks easily, doesn’t regulate temperature, and like plastic, it sweats. We want the pros without the cons, so that’s what we made…

THE SOLUTION

INSULATED GLASS THAT DOESN’T BREAK OR SWEAT.
