Jason: About the Creator

Jason is the founder of ThirtyOne, a clothing brand whose first product is a pair of pants that can be worn in two ways.

Before ThirtyOne, Jason ran a custom keycap business in high school, teaching himself design and manufacturing from scratch. He started college at UC Berkeley, but fashion was always what he cared about most.

Jason joined SPRINT 1 at SLAM & CO to go all-in on building a brand. He stayed for SPRINT 2, took a leave from Berkeley, and after months of prototyping, pattern-making, and production work, sold out of his first run of pre-orders.
