About us
This isn’t just a tube. It’s the result of a 20-year obsession.
Hey, I’m Josh, and I’ve been chasing concerts and collecting show posters for two decades. 85 Dave Matthews shows and 200+ posters later, I finally had enough of bent corners, soaked cardboard, and tubes that were way too tight. I taught myself mechanical engineering, spent a year prototyping, and built the first gruvTube — the wide-body tube designed by a collector, for collectors.
Whether you’ve been to 100 shows or you’re holding your first print, I made this for you — the ones who know the merch table rush, the setlist surprises, and the heartbreak of a damaged poster.

For us, concerts aren’t just a night out — they’re family tradition.
From my first Dave Matthews Band show in 1998 to our son’s very first (check the shirt 😎), we’ve chased the music together for years. Along the way, I’ve collected over 200 show posters — and dealt with all the headaches that come with protecting them.
Bent corners. Tight tubes. Rain-soaked cardboard. We’ve been there.
So I set out to solve it. After dozens of prototypes and more than a few trial runs in the garage, the gruvTube was born — a wide-diameter, collector-designed tube built to protect what matters most to fellow fans.
We’re not some faceless merch brand. We’re just a concert-loving family, and this one’s for the fans who stay ‘til the last encore and line up early for the poster drop.
