Enter the gym portal →Gymside is a launchpad for up-and-coming brands designed for the gym member. We put you in front of gym owners through a curated monthly mystery box, then feed you the real buyer signal you need to pivot, sharpen, and grow - while gyms reorder what they love at wholesale.
Every mystery box is distribution for you and discovery for the gym. The reorder data that comes back is the product - it's how a challenger brand finds its footing before scaling anywhere else.
