Postpone is a social media scheduling tool founded by Grant McConnaughey that grew from a New Year's resolution project to mid-six figures in ARR.

Kettle Chips eventually became the top-selling natural chip in America.

HOKA was founded in 2007 by two French mountain athletes, Jean-Luc Diard and Nicolas Mermoud, who identified a problem with downhill running injury that major footwear brands ignored.

Gymboree began as Joan Barnes' solution to her own isolation as a new mom, evolving from informal playgroups into a cultural phenomenon with hundreds of franchise locations by the 80s and 90s.

Hydro Flask was born when Travis Rosbach couldn't find a water bottle that met his needs—one that was durable, leak-proof, and kept drinks cold.

The company grew to become one of the most recognizable water bottle brands in America, fueled by word-of-mouth and retail partnerships.
