# Janji

> Janji is a Somerville, Massachusetts performance-running company founded by former Washington University teammates Dave Spandorfer and Mike Burnstein. It sells technically detailed apparel, packs, and accessories through its own Shopify store, REI, and specialty running shops, using limited runs, artist collaborations, unusually practical storage, and a five-year product guarantee to stand apart. After 13 years and more than $1 million donated to clean-water initiatives, Janji shifted its giveback model to $10,000 monthly grants for grassroots groups widening access to trail and ultra running.
