The story
Ken Johnson and Andrew Draper started working on the concept for Manpacks in December 2009 and founded the company in January 2010. Manpacks began as an experimental side project, but demand increased. Soon, customer management and the processing of orders turned into a full-time job. Upon launch, the site only offered underwear and socks.
Manpacks was the first American subscription ecommerce service offering men's essentials. Numerous sites have since spawned and imitated Manpacks' business model. Shortly after launch, Manpacks was accepted into Betaspring's startup accelerator program. The company at one time had more than 10,000 subscribers.
